- After a lot of feedback, I decided to post a walk-around of our DIY pure water cart. This is not a comprehensive how-to, but hopefully with these close-ups, and a little explanation, you'll be on your way to your own build. Parts we used below, not a comprehensive list, quantities will vary based on your needs. But this will get you started. And of course, your results may vary, so you assume your own responsibility.
The dolly was used, and craigslist or facebook are usually loaded with similar ones for cheap.

This was my winter project. About $850 invested. Saved me $1500 or more on comparable dual tank system and it works. Lots of flow coming out. Great way to learn how everything works as well.
How is it working for ya?
Thank you for sharing your knowledge kind sir! I have been window cleaning for six years successfully. Thanks to people like you for teaching me along the way.
This is what the Internet should be about!!!
Thank you my brother!!!! * Fist bump and a beer*
Thank you!!! Be blessed with everything you do!!! Thank you for sharing; and caring!!
👍🙏❤️🙏👍
Honestly this looks better and higher quality than anything on the market. Great job and thank you for sharing.
Oh man you just saved me tons! Im switching to soft washing/power washing and high end window cleaning. Just built my interior pure water system and this is gonna be built in the spring! And the list of parts! Tou are a god send my dude!
thank you for taking the time to list all items , great video
Starting build now, just order most everything, only doing single ROI and doing a double inlet with sediment &CTO filter. Thanks for the video!!!!
Thanks bro. I’m picking up a unit tomorrow for $400. I’m going to use the parts to build this system
You did a beautiful job putting that RODI system together.
Thanks, much appreciated
Looks awesome I have a self build system too, going to be upgrading it soon with pump etc. May I make one suggestion though, add another pre filter and stick a 5 micron sediment filter before the carbon block, as you currently are its possible sand and grit will get into the carbon block and reduce its life a lot quicker (Or worse if you have a carbon block filter thats 10 microns or more, it may let small particles through into the osmosis filters and reduce their life too). And sediment filters are cheap as chips, not that carbon is massively expensive but theres a difference that makes having sediment better.
That's a good thought, thanks! I decided to go with one, as it is 5 micron, after checking manufacturer filter change recommendations. Systems that have two pre filters go every 6 months, and systems with 1 are every 3. Because the filters are close in cost, it was better for me to save the weight and initial cost and keep it simpler.
You, my good sir, deserve a nobel prize for this. You deserve all the likes, praise, and goodness in the universe for what you've done. Thank you!!
One question, is there a reason you chose to not involve a RHG pump within your system? Is it just because you're relying on the pressure of the house water? Thanks!
Yeah, we have decent pressure around here and I don't do much super high work, so I wanted as much flow as possible without any extra hookup
This is nice great job 👍 best I've seen so far
Thank you for the video. In the process of building my own.
Question: "I's comming out of the RO's at 1 ppm"... are you running your water through one RO can and then through the second can to get 1 ppm ?
Thank you very much for this video and information, I will use it!
It's....beautiful!!!! I love it
Thanks man, I appreciate it
Do you have a list on the exact quantities that you used on this exact setup?
Love your system! Thank you for the video. I do have a question though. Everything about your cart build make perfect sense to me except the discharge water. Why is there discharge water? Why would that not just continue into the rest of the filter system?
This is a natural part of reverse osmosis, and the reason RO membranes last longer than any filter or DI resin. Rather than trap all the contaminants, the water is split into purified water, and discharge water full of the leftover solids, which gets released continually. If it were trapped, your membrane would be ruined much faster. So if you check the TDS on the discharge water, it's much higher than even your incoming water- it's all the solids that have been separated from the pure water.
I'm not that handy with these things but I wanna give it a shot. 1600 on windowcleaner is a lot
Very nice set up, I used to wash windows when I was younger and my friends fathers company used DI water, could you run this with a pressure washer or do you recommend just filling a tank then running the pressure washer off of that?
This is great video and very well explained, i would like to add 2 of the 1/2” plug for top of the vessels, and seems we need 6 of the 1/2” male barb fittings. I have a quick question so we have to put 5lb resin inside of the 4.5”x10” di right? Is it possible to put the picture for us? Thank you again and much appreciated, man. You helped a lot, and let people save thousands of dollars!
It just has to be filled and packed full. @Stevothewindowcleaner has a great video on how to change resin that shows all you need to know
Glint, can you put the parts of the filters to where to get them please. Great video and great product
God bless you!
I love this thanks for the insight, 1 question. What size is the blue hose that has the 90's and t fittings
Hi there...love the build. Just quick question regarding the RO housing. Mine has 2 openings and I need to plug the middle opening. What do you use to plug those openings?
Just a common not plug, available wherever you but plumbing supplies.
How do you figure out the right bolts and fittings to use? Are you just using nuts to hold the bolts?
Nice work......How do you figure how to set the flow on the the waste water? I have a xero pure and there is no adjustment on that.
I just eyeball honestly and try to match the flow of ones like the xero. It's not too critical in my opinion, just open the valve all the way for ten seconds when you start and when you finish, those ROs will last for years
And thanks!
one quick question, it looks like you are running your DI resin tank upside down, is that just so it will drain when you turn the water off? I have a homemade DI tank that I use for washing my car but I don't currently do any pre-filtering which is quickly destroying my resin. We have extremely hard water here in Phoenix, so I'm starting to look for solutions to save me on resin costs. Plus I noticed after about a yr, the resin starts to give off a fishy smell when using it, so I can only guess that's from leaving water sitting in the tank after use? this solution make perfect sense to me, but I also need to be able to produce about 2 Gallons per minute, to run without a reserve tank.
It's really only an ease of mounting/ logistical thing, it doesn't seem to affect anything.
@@glintwindowcleaning1751 Does the water drain out of the DI resin when you shut off the water? Might be a hidden benefit to having it turned upside down????
@@Vanhamj1 no, I cap it off. But you can drain it for weight if you wish. That may increase the risk of ant-trailing though to be honest.
How would you add a booster pump to this? I am headed to do work at a marina with low water pressure.
Hey there! I did a build as well… not near as pretty but it works. I happened to get my hands on a tucker cart without any of the fillers or housings, but it’s single RO. I’m looking to upgrade like this. My issue is finding an appropriate cart. Do you mind telling me where the cart itself is from?
Found it on Facebook marketplace. Painted it blue for kicks😁
Can you run a 2gmp pressure washer off of this? Or do i need a pump?
Thanks for the very valuable info! Do the DI membranes have to be vertical or can the be horizontal?
Doesn't matter, as long as your DI resin is packed well! Same for all the other filters, they get mounted every which way for different applications.
Would this have sufficient flow for solar panel cleaning?
Very well done, thank you
will this system work with a pressure washer ahead of the unit. I use my R-V Mod unit for washing cars.
I wouldn't personally recommend that, but it's plenty of flow to use on it's own for a final rinse, I do it for my own cats all the time.
@@glintwindowcleaning1751 Cats??? you mean cars???
Thank you for all that you do for the industry,
@@usi9fl lol! Yeah you got it! Thanks, I appreciate it.
Hi and thanks so much for your super helpful video!! What is the link for the DI Housing?
That's strange, it used to be there I swear! It's a geek pure 10x4 inch. You can find them on Amazon and eBay
nice video! I have some questions on this. What is your output pressure on this? As well as inlet and are you using a device to measure flow rate?
That's just dependant on the source, and I don't have devices for that. With any passive system, you can just figure there will be several psi will be lost from whatever the source is. The ro membranes usually have a spec sheet that tells you the percentage pressure drop to expect.
For flow, a stopwatch and a bucket is my go to
What’s the thickness of your metal plate?
1/8" maybe? But it's reinforced with 3/4 square tube stock. It was a bit flimsy so I added that later.
Why is the DI upside down????
That part was assembled in Australia
What is the link for this unit, the frame etc,etc
Hi,
Thank you so much for the info. Much appreciate it!!
What type of Waterfeed Pole are you using? And where does the soap come out through whenever you’re washing a window? I’m new to this. Not sure how all this will work. I hope this is not a dumb question lol.
U don’t need soap, just pure water
Quite alright. There are a lot of great poles available at WCR, jracenstein, and Detroit sponge. The system uses water only. Do some searching, check out the aforementioned sites, the info is out there
I’m in high tds water area 150-165 Chicago. Will this be sufficient?
Absolutely! High tds is what ro is made for. Much more economic in the long run
I see the “Garden hose to quick connect with valve” link is expired now or isn’t working… this is the last part I need to order. Any chance you could find me a new link or a direction to look? Thank you means a lot! 🎉
Just go to window cleaning resource and look for garden hose to wfp hose adapters
I'm still trying to find out why we need to have a constant flow on the RO pressure vessel..
If you're referring to the waste valve, it's because RO is not exactly a filter. Filters catch debris and keep it inside, where RO separates the water into two groups- purified and reject water. The rejected water contains all the solids, and it has to go somewhere, or else the RO membrane will be plugged up and ruined in short order. Hope that helps!
does increasing the waste water flow just increasing the flow coming out of the system? Does it change the tds coming out of the RO membrane? thank you
A few things happen when adjusting waste water. To understand better- more waste water flow=less pure water flow. But it also means less contaminants builds up in the system. That's why most systems built like this will recommend flushing wide open for 20 seconds at the beginning and end of use.
How do you remove the Pex pipe when you are going to change out the filters? Quick connect fittings an option? Thanks!
You could use quick connects if you want but it's not necessary. The curve in the pipe going from the carbon filter to the ro is just enough slack to remove the ro caps. You can also undo the threaded fittings since pex pipe can swivel on it's fittings, many don't realize that so maybe I'll mention in a follow up
Did you use a pex 3/4 brass 1 inch fitting directly for the DI filter, i didn't see it on your parts list.
Yeah, the parts list isn't comprehensive, some things aren't available, and some things will just be different depending on your setup. The list is just a starting point
yeah i got that i have most of everything already just lack some fittings, One other question. I'm going to start also cleaning solar panels with this setup would this setup be a good starting point in your opinion?@@glintwindowcleaning1751
Have you tried using something like this connected to a pressure washer? Wonder if it would work
It could be used as a pre filter only, but there really wouldn't be a lot of benefit. For a spot Free rinse, it's best used on its own
Great work where did you got the small di filter
Link is in the description, most components came from eBay and Amazon. Thanks!
I have 2 dumb questions.
What’s the main benefit to having 2 vessels vs one? Just simply more use before having to change filters? Or are there other benefits?
Could this be permanently mounted to the wall of an enclosed trailer rather than a portable cart, and not leak everywhere? Other than the release water of course.
There are no dumb questions, just dumb people 😆
The benefits are more pure water per minute. The RO vessels only let so much water through per square inch per/time, so more inches=more water. The longevity of all the filters will be the same gallon wise, but less timewise, as that is mostly dependent on the amount of water put through them.
This can all absolutely be mounted somewhere permanently! It's really a matter of preference. A van mount does increase the amount of hose required in many cases, and more hose=more restriction=less pure water per minute. It just depends on your own needs. There's also the danger of freezing in cold environments like mine. I like to be able to wheel it inside for winter!
I might ad that with a van mounted system, the flush water just needs to be routed outside the vehicle.
Not sure if you mentioned it but how many gallons of water do you get from this system
Depends on your source, but 2 gpm is pretty typical
Could it be turned up to fill a tank for pressure washing
Hey i noticed the di cartreidge you have linked doesn’t have the peice inside it the same way xero ones do. is that an issue at all?
Like the xero I had had that white cylinder in the bottom of the di cartridge, but the one you have linked did not have that, not sure what to do.
what pump do you reccomennd to boost flow? II have one for my water tank for detailing, i want more flow.
They sell booster pumps on WCR, jracenstein and the like. Those are pretty ideal for this purpose
thanks for video. I'm confused as to the DI resin I have to buy. is it the XERO DI Cartridge with Resin - 10 Inch, or the XERO Virgin Resin from WCR?
You're welcome! The links in the description get you the needed cartridge, but no resin. From wcr, you can just get virgin resin in bulk. The smallest quantity I think is 1 cubic foot which is plenty for a while.
@@glintwindowcleaning1751 thanks already ordered everything and will be assembling soon
@MTH Power wash still working great! Using it several times a week
I would like to use this to detail my cars and motorcoach. Do you have an idea how many gallons of water the resin will last?
It varies greatly depending on your water, but I can say that the whole purpose of a system like this is to save DI. It always works out cheaper. For me, I get almost a year out of my resin easily, and the system gets used a couple times a week.
Hey man I just built mine up. Can you help me determine the right drain valve size for this setup? 1/8 inch hole good? Or 1/16 inch?
I see youre using the pex ball valve.
I’m not interested in fluctuating release valve
I want it to be fixed as the zero carts are.
Please tell me what size pressure relief valve hole you think this system would need?
Awaiting your response eagerly .
That's going to depend on the membranes you go with. I would do a little research on the percentage of reject water produced, and size it accordingly. You can usually download a spec sheet of a comparable membrane to see. One nice thing about a valve is that you can shut it off for transport so it doesn't leak everywhere.
Where do u get the cart at
Facebook marketplace
How many gallons of water do you run through that setup in a season before you need to do any maintenance
I honestly have never checked. It really depends on water quality, and around here it's quite good. So I change the carbon filter quarterly, and the di probably once a year. I get dozens of jobs out of it for sure
Is there enough flow to hook this up to a pressure washer to wash a car ?
There are larger systems capable of this, but I wouldn't recommend it for this one. Typically the pressure washing would be a separate stage, and then you would use this for a final rinse
Nice build! Do you have a flow restrictor after the RO? Or is that your pressure quick release valve that is spewing the water? Just curious. Building a system and not sure about a pressure regulator. Thanks!
That's just a ball valve that's dumping waste. You can just eyeball the setting on that based on the ro membranes paperwork. They'll say what percent waste water rejection should be.
>4040s are $70 a piece
*checks upload date*
*3 years ago*
Ah... yeah...
Nice . Would this work for a Mobile Detailing set up ? Cheers
Absolutely. I use it to rinse my work van all the time.
Nice, what was the cost?
At the time, I had about $750 in it, which worked out great because an older single stage I built for about $450 sold for $750.
Hope you can help on this for a long time I used the DI tank it was great but I wanted to get fancy and bought the xero pure I didn't do much research the water pressure sucks so bad I have to use a pump now on every single job it's very depressing! Is there anything I can do to increase the water pressure??
A booster pump is good, but the most common mistake is using too much wfp hose. Keep the wfp hose to just enough to run your pole, and use garden hose for the rest of your length, this is the cheapest way to boost flow. It works amazingly, because the pressure drop is exponential for every bit of length of the small hose.
This may be my problem!
@Hooked On Jesus yep I went back to my old DI tank no problems with pressure
The dump valve you leave it on while cleaning? I
That's correct, just a little bit. The spec sheet for whatever RO membrane you use should have amounts of waste water and pure water produced. I've found i can eyeball it based on those ratios. Let it flush wide open for 20 seconds when you first start and when you stop, and that should really take great care of your membranes.
Can I use a system like this to clean solar panels?
Absolutely!
I’m getting really poor pressure through this set up for some reason… my house water pressure is pretty normal but I’m only getting about 1 gallon every 6 minutes through this with the bleeder closed… I built everything exactly as described. I tried removing the pre filter with no change then removed the DI filter with no change. The RO filters are as recommended… not sure where to go from here?
That's a bit odd, let's see how we can help. Shoot me a message on my Facebook business page so I don't miss your replies
Meantime, how much of what hose are you using? How's your TDS incoming and out?
@@glintwindowcleaning1751 TDS is coming in at like 500-700 and out at like 1 or 2 !!! Really working well just not enough pressure. I was running like 150’ of the small flex hose and I since reading more took off the 100 foot section and it’s much better. Is there a way to up the pressure when using that much small flex line?
@@hookedonjesus1716 you can use a booster pump, but the easiest thing is to keep the 8mm hose to just enough to run the pole. We're talking pole length plus twenty feet or so. Then use larger hose to from the machine to that point. I personally love zero-g hose. 100 foot fits in a 5 gallon pale, and it's super durable with a large inner diameter to boot.
@@hookedonjesus1716 with that high of an incoming TDS, you definitely don't want to run the waste valve shut, and flush it wide open for a minute when finished using
What if there's no water supply at customers home,its van mount here,with 100m hose on reel
A tank and a pump would be in order for sure!
I've had one job out of several hundred here with that issue, so we just did it the old fashioned way.
Hi there Would that be ok if I only use 1 RO ?
Absolutely! It will produce less pure water per minute, but it all depends on your needs.
What about under hi pressure
Depends on your definition of high pressure. This can be used with a booster pump to get even more flow if you like, just check all your filter specs and stay in the manufacturer stated limits.
Any issues with installing the di filter housing upside down? Searching online says not to, but I can't see that really being a problem with DI, right?
None at all. Almost every pure water cart on the market does it that way.
@@glintwindowcleaning1751 do you have to push the pressure relief button every time you run the system?
@@isaacholzwarth Nope, never been an issue. Only sometimes to help release when removing the housing for a resin change
@@glintwindowcleaning1751 cool, thanks! Just finished up my own build and was worried that would have to be done every time, which would be annoying.
@@isaacholzwarth excellent! How do you like it?
Can I use a 21 inch ro instead of the 40 8nch?
There is actually a system on WCR that uses 2 21s. It works the same as a single 40 ro system. I wouldn't do a single 21 though, just not enough flow
Thanks for the reply.
I just came across your video. Awesome job! I'm new to all of this and these may be dumb questions. I did have a couple questions. Is there a reason you opted for the smaller
10" x 2.5" pre filter and housing instead of the 10" x 4.5" and then the same for the DI housing you went for the 10" instead of the 20"... Is there a benefit to the smaller sizes or is bigger better? I'm ready to start ordering everything and putting it together. lol
Weight was the biggest factor. There's other factors though. The prefilter definitely doesn't need to be any bigger, it needs changed quarterly regardless, and a carbon filter is not very restrictive so it can be the smaller size. As for di, the only advantage to larger is longer time between di resin changes. Our water TDS is mostly in the low 100s or less around here, so I get excellent di life as it is, no need for the extra weight. But if you live in an area with really high TDS, the bigger di canister might be wise.
Where did you get the cart?
I just found it used on Facebook. There always seems to be a few out there for 30 bucks or less
What was your total cost for the build
About $750. Wait for sales, and pick up used pressure vessels from a Culligan store or somewhere, and you can do it even cheaper.
What PPM can this work up to? Water I’m using is about 200ppm would it work?
200 shouldn't be any issue. If the ro reduces 90%, that gets you to 20, easy for di to finish off
Is the DI housing it’s a filter & resin? Thank you for the help I’m in the process of building a cart myself🔥
@@GoinShoots if understand correctly, you'll need the filter housing, then the resin cartridge for inside of that, and resin to fill that cartridge with.
Thank you
Pex isn't rated for UV. Expect to replace it soon.
My old system begs to differ. May not be rated for it, but it's holding great, 2 years in
More than anything, uv degrades pex's ability to resist chlorine, of which trace amounts in your water eat the pipe over time. The carbon filter removes all that before it hits the pex.
What's the total weight ? Looks heavy!
It's definitely heavy, like any double ro unit. Unsure of the exact pounds
Why not get 20" filters? They don't cost a lot more but they last a lot longer? your DI filter is upside down.
2 ressons- Weight savings, and we have pretty clean water around here already. I change di once or twice a year so it's fine. And yes the filter is upside down. All the cool kids are wearing em that way.
Hi i'm building the same set up (thx) hopefully I can contact you for any question, 👍👊
Anytime!
Do you have any for sale ?
Nope, this is strictly a broad guide to build your own
Where is the name of the carbon filter
It's listed in the description as pre-filter. Sorry for the confusion. Any 2.5 x 10 5 micron carbon block filter and housing will do.
@@glintwindowcleaning1751 thank
Where do I order the parts

@@glintwindowcleaning1751 thanks
I’m not a window washer but I’m am a Reverse Osmosis expert. That 2.5”x10” CBC Prefilter is too small. Should be a 4.5”x20”.
no its not😂
def not an expert then
If we want to get really technical, this system shouldn't even work as tap pressure is lower than what the membrane operating range is. But window cleaning is a unique application and product designers easy smarter than us have come up with tried and true systems using this general design long before I did. The filter size is fine as long as it's changed quarterly. Thanks for the input though!
this shi is not working, i built this and i get no pressure and barely any water coming out the di housing
So, there are a few potential issues- if you'd like, send me an email glintpros@gmail.com
Please include pictures of your system and what you've done so far to address any issues. Let's get this thing working for you!
after sales service and online consultation you the man@@glintwindowcleaning1751
Please help me find the di like you have here!! I can’t find it anywhere!!!!
Just look for 4x10" whole house filter. Or 4x20" if you have really hard water in your area
Okay. I pick up most of the pieces for this project. Where do I get those square bolts that go on the center top of of the 4040 pressure vessels?
@@vschampion I'm so sorry I missed your question. The notifications here aren't always great. Hopefully you figured it out, but they're just npt plugs available at most hardware stores.
