I was here for my dishwasher, ended up doing a bible study with the Ecclesiastes verse. Thank you very much for the help and for the verse. Be blessed!
This is the best ever video explaining the use of the HIGH LOOP!! My installer did not do that and He came back today, as I occasionally had water coming back into my dishwasher. Having seen your video i was able to explain to him that it had nothing to do with the loop that the manufacturer installs on the side of the dishwasher. He was about to pull out the dishwasher and start tinkering with the manufacturers loop and I explained to him, all he had to do is to take the hose which was attached to my disposal and loop it up at 32 inches or as high as possible under the counter with the CLAMP and Screw your video shows so well. The need to remove the dishwasher was unnecessary and he did exactly what your video explains and the install (with the proper tools which he had) took about 2 minutes. Thank you for such a great and informative video. it was extremely informative and helpful Bill G. Melrose Massachusetts
Thank you for the video, specifically the comments surrounding the sufficiency of the high loop and the air gap not being “the only good or correct way” as some others have claimed on the internet.
I noticed water flowing into my dishwasher when my garbage disposal was blocked. I saw a lot of slack in the dishwasher hose. I was searching online about the slack when I stumped upon dishwasher high loop. I have never heard of it. Your video explained everything! Thank you so much!! I can't believe Home Depot installation (which I paid for) did not bother to put in the high loop for me. I guess it was during the pandemic and they were short handed.
I think a lot of installers are just lazy and don't want to do it. I bought a dishwasher direct from Whirlpool and their installation guys didn't do it either.
Hi Reuben, thank you for this video! Very good to know. I just had to replace the coupler that connects my dishwasher drain hose to the Disposal. The drain hose was just run across the bottom of the cabinet from the dishwasher. They used a 5/8" rubber hose from Napa (Auto Parts)- so I guess it is something meant for a car... It's been this way for probably 25-30 years. I only had enough extra hose to get the "high loop" ~2 inches above the bottom of the sink.
Thank you very much for this video. It answers the exact question I had concerning the high loop on the side of the dishwasher. I will make sure to put another high loop under the sink. Thanks again.
Good luck in Minnesota, what those pesky law makers do! Someone installed our dishwasher with the long return hose just laying on the floor of cabinet. Which of course has led to some foul odors coming from the dishwasher. I'm glad to hear the high loop method will work as well as the air gap. My sink doesn't have a hole for an air gap. And I was actually considering drilling one. But thanks to your counsel, I'll just use the "High Loop" method. Thanks very much. I was not looking forward to drilling an inch and half hole in stainless steel.
FYI My new Bosch dishwasher said the clip to hold the drain hose for the high loop should not be metal. Maybe it's a rust thing that then might puncture the hose or fall.
I'm doing one right now, my third installation. This time I'm just going to drill the hole high under the counter from DW to drain, no need for a clamp.
Thank you for the video!. Im a homeowner fixing a miserable leak from a Bosch 800 series dishwasher drain hose. Fortunately, the leak is right at the end of the bogus corrugated white drain hose, which connects to the drain. I envisioned replacing the drain hose would be slightly miserable because I would have to slide the dishwasher out from under the counter. I watched a video on replacing this hose and the process is insanity. A technician would most likely charge $600 to replace the hose because you have to take the dishwasher apart.
Had some fat guy at Home Depot insist that I needed an air gap in Illinois, and that the dishwasher drain tube should never go into the garbage disposal. I told him I'm not a pro, I don't care what the code is and I'm hooking it into the dishwasher because that's how it's designed. He called a manager because I was being "hostile.". I was so disturbed by the guy, I told the manager that I had purchased a $2000 washer/dryer and I'd be happy to return it. So she gave me 10% off.
Thank you Reuben, I will be installing my dishwasher loop correctly because of you. One thing leads to another. What is the other purpose for the loop on the side of the dishwasher?
Our dishwasher was installed with the drain hose at the top-back cabinet that angles down to the disposal. I've watched videos of people installing a dishwasher for the first time and they still drill the cabinet hole at the bottom. Seems counter-productive when installing a first time dishwasher.
I have two queries sir if you could kindly answer: 1) Our dishwasher was causing black spots all over our dishes, glasses etc. A technician came in and when he could not find any issue with the filters, salt level, water hardness, propellors etc, he said the reason could be that there was a loop and it may have been causing the wastage to go back into the dishwasher 2) So now what we did was raise the entire dishwasher through a bench so that “the point at which the drain hose pipe is connected to the dishwasher” is higher than the “ end of the drain hose pipe” that goes into the separate drain itself. The problem we are now facing is that the water keeping draining while the dishwasher is taking water for a wash cycle and thus it isn’t functioning at all. Someone told me this is because the point at which drain hose connects with the dishwasher should never be higher than the end of the drain hose pipe. So we are stuck between a rock and a hard place. Can you kindly suggest what we do about this?
The high loop on dishwasher serves a similar purpose but in the opposite direction: It's to prevent waste water leaving the dishwasher from coming back to the dishwasher. As you said, it's definitely not a replacement to a high loop to the sink drain.
you are correct. The loop he pictured on the side of the washer is called a "condensation tube". It's part of most modern washers and serves a different purpose.
For a high loop, the bracket must be plastic. Not a metal bracket. This is stated in all dishwasher and washing machine manuals. The pipe moves a bit all the time machine works and metal cut plastic pipe. In 99% of cases, this loop goes beyond the sink bowl. The space there is 3-4 inches wide. Therefore, it cannot be mounted as simply as shown in this video. To do this, you need to make a support that is attached to the bottom.
I have a brand new Bosch dishwasher that I hardly use. When I was looking under my sink, I noticed that the drain line going into the disposal from the Bosch had water in it. The water is nice and clean. The drain reservoir is empty and the filters are nice and clean… the dishwasher is effectively brand new. Less than one year old. I reset the cycle and then manually did a rinse and drain cycle… I was able to see the water being flushed through the hose since it’s a clear hose. After the cycle, there was still water left in the line. Is this normal? And if not, what should I look for? There are no error codes in the dishwasher is great at washing the dishes… No performance problems. Justice water sitting in that hose that’s bugging me.
Question; we have the high loop but was installed with a loop going below the drain pipe a few inches before looping up again to connect to the drain, is that Right?? After using the washer there is over an inch of water at the bottom and the line is clear.. Also Is there a pump that could be bad? Thanks and great video with exciting topic!!
Please help me. My washer drain hose does not come in through the bottom of the under sink cabinet. It comes from a hole in the top of the cabinet. So I just kept it up high under the cabinet surface behind the sink and then brought it down to the attachment to the disposal. Did I do the right thing?
Would it be better to have the high loop just behind the DW rather than next to the sink drain? I mean, if the high loop is installed just behind the dishwasher then there is less waste water between the dishwasher and the loop. Also, if the high loop is behind the dishwasher, then the height at which the drain hose connects to the sink drain is irrelevant as long as it attached before the p-trap .. or I may be wrong?
My air gap was leaking suds from handwashing on the sink (dishwasher turned OFF). The plumber completely unhooked the hose this time from my air gap and it looks to be connected straight to my sink in an effort to stop the suds from spilling over the air gap. It looks like he didnt know why it was still leaking suds after the first time trying to fix it. IS THIS OK?? I haven't used the dishwasher yet and afraid that he may have fcked it up. I live in CA btw.
Anyone know how long the loop should be. In your demo you show one clip creating a pretty narrow loop. That is not the issue and is a proper loop, but in my situation I have to have my drain hose go across another cabinet before it gets to the under sink cabinet and drain. I don't want to run it across the bottom of the cabinet as we need the storage space it provides. So, I want to run the drain hose horizontal into the cabinet and then run it vertically immediately to get to the top of the cabinet and then run it over, along the top of the cabinet, to a drain fitting. So, in effect, I have a loop that is 30+" long. Are there any issues with this? Anyone come across this? Thanks
I have had a high loop for about 25 years or more. Recently, after using the dishwasher, the water backed up into the sink. I turned on the garbage disposal. The water was sucked down from the sink. I turned off the disposal. The water flooded right back up into the sink. It seems to me the high loop has failed. I am having an air gap installed. My question is: is there a way to recover from this problem without installing the air gap? Can the siphon action be corrected? It's too late for me, but the problem troubles me. I don't understand.
This message is 7 months old, but I am curious whether you got the problem solved? Not sure how you had the high loop set up, whether your hose went into the disposal or directly to the drain line. But it sounds like a clog somewhere was responsible for this problem. They high loop may have prevented the water from backing up into your dishwasher, but I doubt it could have caused the problem. What did you find out, @Mickey Lee?
@@isabellavision I caved in and installed an air vent simple because it is the code, however unnecessary. In the end, the drain was seriously blocked as a result of a multi-year draught when stuff gets into the air vent followed by a very heavy set of rainstorms which flushed all that stuff way down the drain. I live in a multi-level apartment building.
@@MickyELee Thanks for the update. Air gaps were also made code in my state in around 2016, but that rule was rescinded late last year after much protest and evaluation of evidence. Maybe other states will follow suit. As for air vent clogs, there's a video on the RUclips channel "Stud Pack" of them working to clear a vent clogged by squirrels "burying" nuts by dropping them down the vent. Not relevant to your case, but entertaining and interesting to watch. Thanks again.
This exact problem just happened to me and flooding my fucking kitchen. The dishwasher discharge backed up and flooded the dishwasher. This overflowed and ruined my kitchen as well as leaked water into the basement.
Ours is that way. As long as the water doesn't flow back up the tube and into the washer. Highly unlikely when the tube is installed through the top of the cabinet. I've never had issues with a GE or KitchenAid washer.
Question: We have a high loop under sink are. Why is water from running faucet backing up into dishwasher through the drain tube after only AFTER running a cycle? Pressure Build up? Suction? Plumber at first did NOT do high loop and we were getting water in dishwasher. He came back and did the high loop and at first all seemed fine. After running a full cycle I noticed that water was trickling back down the drain hose (I visibly could see through the tube) and back into the dishwasher when running the faucet and it was filling up the dishwasher. It is draining just fine from the dishwasher, but after 1 full complete cycle the water is running from the faucet and going down the drain, some of it it diverts and trickles back down the dishwasher drain hose causing it to fill up the dishwasher. This would only happen after running a full cycle. What I determined is that pressure is building up in the hose after a cycle is run. After one complete cycle, when I release the clamp holding the drain hose, you can hear the air release. When I do this, it stops the water from going into the dishwasher from the running faucet/drain, until a full cycle is run again. Please note that the hose length is not known because it is located in a dead corner space under the counter in between the dishwasher and Sink area. It is not a side by side set-up. Is the hose too Long? Is there possibly a large loop in dead space that builds up pressure, in turn pulling some water when I run the faucet? Should I shorten the drain tube. (Problem is this was installed BEFORE the counter was put in.
Do you have a video on how to undo an air gap and do a high-loop instead? I'm in WA State, though, and believe we still have to have them in our homes. I want to use the hole in my counter for a water filter spout, instead, so I'll just put the air gap back in when we move. :)
Question about dishwasher install: Our house is a little older and it has a 1 1/2" inch drain under the sink, 1 1/2" p-trap, then goes into the wall. A local plumber told me I need to completely re-plumb the drain under the sink and into our basement with a complete 2" line in order to install our new dishwasher. Are 2" drains required for modern dishwashers, or will 1 1/2" work?
An air gap is simple, common sense good practice. Think of what it does and why it should be mandatory. It allows the dirty water from the dishwasher to drain out easily at a safe height above the level of the sink. More important, it prevents dirty water from the sink drain from draining back into the dishwasher. The sink trap could back up taking the path of least resistance draining into the dishwasher instead of the sink. Make the hole in the counter top and install the simple device for simple sanitary precautions. Also route the dishwasher drain hose and make proper connections which allow smooth flow.
The tube and hose on the side of most modern dishwashers is NOT a drain line. It's called a "condensation tube". The tube pictured on the left side of the washer in this video is a condensation tube. This tube is to handle the condensation inside of the washer created by temperature differences between the hot water inside the washer and the ambient air. Some say it can also alleviate a vacuum effect that can be created when the washer cools down from being heated. Test this...take a gallon milk jug, fill with boiling water, pour out the water, then cap the jug. As it cools it will collapse due to reduced interior pressure. This high loop created in the actual drain line does in fact prevent the backup of dirty water into the dishwasher. It's acting as a fail safe.
Ruben, your wrong! Some dishwasher manufactures recommend a low target point in the cabinets for drilling a hole for the drain hose. Silly I know, but they don't all require a high point hole drilled or high loop. Get facts straight before making videos man.. I have an LG washer & the manual has a low target point drill hole in the cabinets.
It's you who has his facts wrong. All of the lines from the dishwasher go through one hole in the back/bottom of the cabinet. This is so nothing gets pinched when the dishwasher is pushed all the way into the cabinet space. Once inside the sink cabinet, the drain line then bends up to the underside of the cabinet where it is secured thus creating the high loop there before coming back down to either the disposal or dishwasher wye fitting in the sink drain.
just because the manufacturer says an external loop is required doesnt mean it is actually required. you should understand the physics and explain why the internal high loop doesnt suffice.
I was here for my dishwasher, ended up doing a bible study with the Ecclesiastes verse. Thank you very much for the help and for the verse. Be blessed!

This high loop created in the actual drain line does in fact prevent the backup of dirty water into the dishwasher. It's acting as a fail safe.
How about showing us
It's called a self tap not tec screw, across all our trades
Love the Bible verse !!!
Thx! I’m going to use duct tape👍
😅
Unless. Wtf
Ruben, your wrong! Some dishwasher manufactures recommend a low target point in the cabinets for drilling a hole for the drain hose. Silly I know, but they don't all require a high point hole drilled or high loop. Get facts straight before making videos man.. I have an LG washer & the manual has a low target point drill hole in the cabinets.
It's you who has his facts wrong. All of the lines from the dishwasher go through one hole in the back/bottom of the cabinet. This is so nothing gets pinched when the dishwasher is pushed all the way into the cabinet space. Once inside the sink cabinet, the drain line then bends up to the underside of the cabinet where it is secured thus creating the high loop there before coming back down to either the disposal or dishwasher wye fitting in the sink drain.
just because the manufacturer says an external loop is required doesnt mean it is actually required. you should understand the physics and explain why the internal high loop doesnt suffice.
Thank you Reuben! I love the Ecclesiastes quote! Try 1 Corinthians 10:31 as well. :)
