This was fantastic! Best I've seen yet... thank you
You’re welcome! Hope you enjoy it if you end up building one
I know this took a great deal of time and effort. You did a great job. Thanks for the information.
Yes it did! Hope it helps
Thank you so much for making this video, it has helped me a lot.
Thanks Riley! We are glad you found it beneficial 😊
you're such a G for making this cheers bro
Haha glad you enjoyed it! I’ll be dropping a version 2 here soon that’s a little more lightweight. Original cart is still running strong though!
Thank you. I appreciate this information.
Glad it was helpful!
I wanted to send out a genuine thank you. I used your info and built my system to just about mimick yours. Turned out great and works awesome. I appreciate your time and effort.
Thanks for the kind words! Glad it worked out for you and saved you some money haha
This is rad. What did your pricing come out to?
Thank you for sharing
You bet!
Good advice .
Thank you!
One thing I didn't catch was where the bypass/discharge line goes to. Would that be just on the ground, or where? Great and thorough explanation by the way! Very much appreciated.
Yep! I just adjust the hose so it discharges into the grass or away from the cart onto the concrete. It’s just hard water discharge
Nice video man, very well done! How many GPM are you getting out of this system? Wondering if its enough flow to have a spotless free rinse on cars
Thanks! I’m getting somewhere between 0.5 and 1 GPM. You would probably want to run several RO membranes in parallel to get higher flow for a car rinsing system.
I have a tank with pump for rinsing cars
Ideally, you would want a tank for the RO water with a pump and bypass to your resin filter (will reduce your PPM to 0), for rinsing your cars.
Where did you get that plate to mount the filter to? And do you have schematics for routing the hoses?
The mounting plate actually comes with the filter housing.
So I want to build a high flow system for my hydroponic system. I don’t need DI. Do you know what the TDS is from out of the RO only ? What is the GPD that this system will do ? Thanks !
Our RO was putting out around 20 TDS with incoming around 300. The Axeon membrane in the video will do 2500GPD at 80 psi. It’s a high flow membrane
if the ro was hooked up to just a garden hose, what would the output be like? I have a di cart for pressure washing my cars and was wondering if i can use the ro as an inline prefilter before my di tank but i suspect that the ro membrane is pretty restrictive because all the set ups I have seen incorporates a tank to hold the water after it has gone through the ro and then it is pumped into the di via booster and then to the pressure washer. Would a hi flo ro membrane help?
At the end of the day, the single RO is always going to be the most restrictive. The Axeon membrane linked in this video was the highest flow at low pressure (garden hose) that I could find. But I think if you’re trying to feed a pressure washer, I’d look at running multiple RO membranes in parallel.
What is the waste water discharge ratio procedure ? Are using tds to set up flow or purely water ratio like 4 to 1 ? . I’m not using a DI filter . This if for my hydroponic setup .
You can test tds to get the right reject vs clean flow rate for your hydroponic setup. Time is money for window washing so I’ll leave my discharge a little lower to get more flow through the DI tank. Resin is cheap!
Would you say this more comparable to the Xero Pure or Pure Plus in performance?
Thanks for the video!!
You’re welcome! Same initial filtering as the Pure but it’s got a higher flow RO membrane and DI tank than both of those options so you’ll probably end up with better flow out of this custom build than either one of those options.
I live in Las Vegas and need the best filter for sand and carbon reverse osmosis. Do you feel that this build is suitable for my needs?
Yeah! You could consider adding an extra sediment filter in front of the carbon filter. That would catch all the large particles and preserve the rest of the system.
Very informative thank you.
I’m thinking install something for my mobile detailer van, do you know if I don’t put the RO filter just , one Sediment + 1 carbon then the resin filter, I mean those sd+carbon filter helps at all ? If yes do you know if from my tap water I get 300 TDS, how much dose remove before the resin filter ?
How many gallons does this system get before the DI resin needs replaced. most di canisters total around 250-300 gallons without the r.o. system. my guess is around 10x the use?
Totally depends on your incoming TDS and how low you can get the outgoing TDS from the RO membrane. Our TDS at the DI inlet is around 25 so our expected life is 5000+ gallons. There is a chart on the Window Cleaner website for the DI resin tank that shows expected life
I just completed the same build and the water pressure coming out of the DI tank is the same, but doesn’t seem to be enough to come efficiently out of the water fed pole, any ideas why? Do I need a booster pump? Different pole?
Yeah, if your flow is too low you’d probably want to add a booster pump. Flow to a WFP in general isn’t going to be super high. Give it a try first on your own windows and see if you can adjust the RO bypass to get the flow you need.
Thank you ! all is possible. What was you last price and time doing this?
I believe around $1100 but cost can be reduced by downsizing the DI tank which is a bit overkill or using a less premium RO membrane. Full parts list in the description for accurate pricing.
With nearly half a year of usage, are you happy with the set up as is, or have you made changes to the system?
We are still really happy with this set up! In fact, we have considered building a few more, either for our use or to sell.
@@pressurewashnerdsin wich city and state are you?
Is it possible with your system to use tap water for prewashing when i have very dirty Windows? and how to do it?
Yes, there is no downside to rinsing first with a garden hose or similar, and then using the RO/DI system.
Most RO systems have a sediment filter before carbon. Do you recommend?
Depends on use. We are primarily a pressure washing company so using a sediment filter to prolong the life of our carbon filter didn’t make sense for us. If you’re running this daily or constant for another application then yes, add the sediment for sure.
@@pressurewashnerds Thanks , I want to use to lower town water TDS so I can add fertilizers to get back to about 1000 tds . What is the rejection rate you dial it to ? 1:1 to get 20 TDS ? Thanks again . This will save me $..
need to check the water 3 places 1 incoming 2 after R0 3 after DI. Outer wise you don't know. I say that because i ran 450+ TDS thru DI and still tested 0 but rosin didn't last.
Yep! I didn’t cover it in the video but my water at the tap was around 350 tds, after RO was 18-40 depending on bypass, and post DI zero.
I’m having a hard time finding a high flow high pressure booster pump. My house is only 45 psi
Any luck? Sites like Window Cleaner Resource and Detroit Sponge have some options for booster pumps but they’re a bit pricey
I built one similar and mine is getting no water pressure through the water fed pole and out the di tank
Check all of your connections/fittings. Could also be a supply issue from your main connection.
How GPD do you think this set up would produce?
I’d estimate around 1200-1500 GPD with 60 psi at inlet but totally depends on inlet pressure
Do you have a parts list?
Everything is linked in the description for you
I’m getting like 25 tds any tips?
Sometimes the supply can be too contaminated to get tds down to an extremely low level.
Only advice would be to keep messing with the amount of discharge your system is putting out to see if you can get it down any lower than that!
@@pressurewashnerds my tds out of the ro tank is 20-25. My tds coming out of my di tank is also 20-25. Is there a chance my di tank isn’t working?
@Allussion sounds like the resin needs replaced. Water should always leave the DI near zero unless it needs replaced.
Hey Dillon. I have a question. I designed my system just like yours. I went with 1/2" fittings. My inlet tank at the DI swivel fitting leaks. Is that a pressure relief fitting. I actually removed it and re-teflon taped it. The thread is not leaking. It's leaking at the rotating portion of the fitting. Your opinion?
The fitting at the outlet? I’ve heard they crack easily so I went ahead and bought a brass backup from Window Cleaning Resource in their waterfed fittings section.

How much did all the system cost you ?
It was under $1k total
Is that including the pole ? How much you think it would cost me with a double membrane I’m from Arizona and the water is really hard over here
Just wondering what type of resin are u using ?
Virgin DI resin from Window Cleaning Resource
What was the total cost of the build?
I believe around $1100 but you can reduce cost with smaller DI tank. Full parts list in description if you want to price things out
