These guys did a great job. I just want to mention for anyone coming across this video that, if the disposal ever clogs and fills up, the waste water will go back through the drain hose and fill up the dishwasher. An air gap is important to prevent that. Even if the plumbing code doesn't require an air gap in your area, it's good practice to form a loop in the drain hose and secure the top of the loop to the under side of the sink so it sits above the outlet in the disposal. That way the water won't go into the dishwasher unless it almost completely fills up the sink.

I still don’t understand why local cities don’t require back-flow prevention on residential houses. They are required on every single commercial property for landscape, domestic, fire lines external by the meter and internal on every “hazard” or “potential hazard” . Yet I can almost guarantee that every house hold is far more dangerous to our city’s water as a lot of humans are gross , 99.9% of humans can’t figure out how to screw in a light bulb let alone try and explain the hazards of back siphonage and the potential problems there creating in the house if there water gets back fed into the city’s water. A simple Reduced pressure back-flow on every house main , and laws for commercial appliances such as fridges and such to come with built in air gaps , or DC or whatever protection they can would drastically protect all of our water we all use ...

You can also put a non return ( 1 way ) valve at the disposal to avoid water going into the dishwasher. Some dishwashers already have one but it's quite rare so I'd say better safe than sorry.

That,s the first thing I noticed that there's no high loop, anywho, if you're ever in a situation where they're using an air gap, if it ever and causes water to come out of the air gap, run a 3-foot coaxial through the air gap by removing the chrome cap cover, remove the cover to access the drain tube, through there run the coaxial cable down then pull it out through the garbage disposal side, just reach inside the garbage disposal from the g/d drain side and pull the coaxial cable up and out of the drain and that will clear your drain. Then replace the air gap cover and chrome cap and you're back in business

That was my question , another youtuber said , hose should be above the disposals connector… know I know why . Thxs

Nice of you all to upload the video. Always a great sound to hear that drain working and find out you dont have to get under the house or tear a wall out.

Since you are not running an air break, the drain hose from the dishwasher should have a high rise loop. Basically the hose entering into the sink cabinet should loop up to the bottom of the countertop and then come down to the connector at the disposal.

This video is very useful. Step by step narration helps. It is down right educational in fixing drain clogs from DW or Sink. Great job.

Thank you, Guys! Best vid of them all! I’ve gone through 5 videos and not one mentioned breaking out the plug in the disposal drain inlet. I’ve been flooding for a week, tried everything and pulling my hair out. Come to find out, a hammer and screw driver breaks that seal. You saved me $$ because I almost called for backup

Just 1 observation you might want to add to the video, manufacturers of dishwashers recommend that you make a high loop for the dishwasher drain hose to prevent the food residue from clogging up the one way valve on the d/w. A hint I found out after reading the install instructions when I got a mildew-like smell from my new dishwasher.

The high loop is a must have. Great observation.

Glad I found this. Usually, I call a plumber but I'm wanting to see if I can fix it myself. The kitchen sink has been slow to drain for a while and I sometimes have to run water through the disposal to get the regular sink to drain. This will usually 'unclog' the drain for a couple of days. I've noticed that it 'gurgles' and an air bubble comes up the regular sink side, after which the sink will drain. Additionally, nasty water has now backed up into the dishwasher. The information and clear demonstration presented here will definitely be my guide.

Good video as always! The premise for the connection of the dishwasher to the disposal, initially, was to chop up any large food particles that made it out of the dishwasher. With better tech in the dishwashers nowadays, it is almost not necessary, but I will install the connection given the chance. With an air gap or high point in the hose.

Very very nice. I have worked on about a dozen homes throughout life but I couldn’t remember all the pieces names. Not only did he explain everything, but he named the pieces and the typical sizes. Really helps. Great teacher. Has patience in doing so. I’m sure frustration kicks in from time to time but we sure need these guys because they speak from experience and wisdom. Great work. Excellent video taking.

And by letting them know take a picture the best way to show what you have at the house instead of trying to explain one person sees one picture and you're telling another good job Paul and Jordan keep recording I'm going to keep watching God bless you guys

I love you! Trying to install a dishwasher that wouldn't drain. I was all ready to go to the store and get new pipes and wanted to watch a video about how to do it correctly.

Plus we removed the Air Vent, Soap dispenser assembly from the sink and plugged the holes at the top with Stainless plugs. Then I had him replace the entire faucet. We installed a Single valve facet with the extendible/retractable spout. Kids are not shown how to work on things nowadays. They need to be taught to work on things around the house.

Drain looks good. The main reason your dishwasher is draining back into itself is cuz the hose is on the bottom of a floor.( that's why we drill two holes in the cabinet) The one on the top for the drain hose & one on the bottom for the water & electric. And dont forget 2 make a loop. 2nd trick is to put a small piece of copper in the hose before you tighten down the hose clamps.

Yeah, hose should be elevated above the disposal. If you are doing dishes and the disposal gets backed-up, the water will bypass to the dishwasher. I’m guessing the hose was installed that way because the DW isn’t next to the sink like it should be. The hose probably goes under the corner cabinet. That’s what happens in older homes where a DW is installed after the kitchen is built. 🤨

Great video Paul I really enjoy the way you take to time to explain why and how you are repairing the plumbing. Paul if they purchased a disposer with a stainless steel smashing drum that would eliminate any problem with the galvanized coating wearing off. I experienced that problem so I swapped out the disposer with one that had a stainless steel smashing drum. 1 1/2 years later no odor and with 1 1/4 HP the disposer never clogs. Also it is vital to create a high loop with the dishwasher drain to avoid backup of the dirty water. One last thing most codes require a GFCI outlet under the kitchen sink. Was that an oversight by the homeowner?

Fun Facts: There are often times blades in the output of a dishwasher and in some toilets too. I had no idea till I discovered it myself a few times, LOL. Micro Rant: One thing I can't stand is when people know there will be someone working in a certain area of their house and the don't clear it of their immediate clutter. Like it wouldn't have taken 2 minutes to put away the clean dishes and find an alternative place to thaw their dinner. It's just part of good housekeeping and being a good host for that matter. Even though the people there aren't guests in the usual manner they are guests in a sense and should not have to deal with your crap, that is one reason how and why people get marked up prices IMO. Great fix, it's actually super simple but really intimidating for someone who's never done it, the plumbing in the wall on the other hand is challenging and has plenty of reason to be intimidated by it. :)

Hey have a great day, lovin' the content, I watch this channel everyday and have learned tons from you guys, thanks. :)

This is an incredibly informative video. I've been through this so many times. My first problem was not noticing there was two separate sections on that pipe wall. One for kitchen. One for bath. I have various extra parts around so when I'd buy the wrong kit I could rig it together. I stumbled on to the separate sections one day and only because I bought the parts at a Walmart this time. They were clearly marked. You covered all that. You covered the bevel washers. The metal pipe in disposal and the connections everywhere. Excellent video. I do have a question though. The dishwasher there doesn't seem to have that backflow drain at the top but mine does but my sink is stainless no hole pre cut. So that drain is right next to sink in counter top. Lately it isn't drain into the sink and its ruinibg the counter top. I have the drain hose hooked to garbage disposal. Do I need that other drain up there? I'm getting counter damage fast. I have cleared dishwasher drain it has pressure. I just know drilling stainless gives me a headache. Dont want to do it because then I have a hole in a formica counter to fix. Can I cap that thing off or what?

Go to your local hardware or big box store and get a stepper bit, (cone shaped drill bit). It will do a very clean hole in any stainless sink. I install r/o systems so I know the first one is scary, my first was a high end elkay but Jesus was with me and it came out perfect. It is almost addicting, just put an overflow in my new stainless washtub. :)

You did a awesome job! But you need a high point in the dishwasher drain hose under the sink. The dishwasher pump runs about 20 seconds so when it’s done if there is water left in the hose it will flow back into the dishwasher.

I have found that the real test is to fill the sink with a stopper in there, then pull the stopper and let it drain all at once. You will see connections leak that wouldn't with just running water, but will with the huge inrush. Not everyone fills their sink like that but some people do. Good to know either way though. (which you did 30 seconds later haha)

This is a really great video now I would guess so my scenario is my dishwasher without a dishwasher was broken so it had a new one is it would never dry the dishes were always wet and with the new dishwasher it’s the same thing so would that be because the dishwasher is not draining properly you think and when I looked under my sink the plumbing looks so much more complicated than that so just a quick question

Just a quick note, you guys done a great job and video, I'll would of added c clips to the hose and have it neatly against the wall and out the way, Most of the time when you open the door, it looks like a bomb gone off, shopping bags everywhere. So many of the same cleaning products and every bloody thing that could not fit in the other draws lol

Nice video. Should raise the hose going from the disposal to the dishwasher above the disposal connection. This creates an uphill, high loop, and prevents dirty water and debris from spitting out of the disposal, then running directly downhill into the dishwasher, clogging valves, and such.

It's amazing that people somehow have the idea that dishwashing powder corrodes disposal blades, when the manufacturers build a drainage port right into the system. People wash their metal pots, flatware and knives in the dishwasher for -years- decades with little to no trouble with corrosion. The dishwasher effluent is more likely to _clean_ the blades off than damage those. I'm glad you now know, and that someone has a widely viewed video showing a great underutilised feature.

Last time I replaced the drain pipe under my sink I too just used a regular Tee. Every time the disposal would run, it shot up into the other sink half. Using a Tee with a baffle to divert that flow downward solves that. That however was a pain to source and I had to order online. Wish the big hardware stores actually carried them in my area.

Yes the dishwasher discharge needs to be as high as you can get it. I have to raise it up in about every other sink I get under. I have seen many kitchen floors flooded because the sink will not drain and water goes out into the dishwasher and all over the floor

Does the disposal outlet have to be even with or higher than the drain connection in the wall? If the disposal outlet is lower than the wall drain connection, will there be standing water in the disposal from the p-trap? Thx,

For the water test: 1st briefly run a little through each sink bowl, then run the dishwasher, and last mostly fill at least the disposal sink bowl then release water with disposal running. The last step is the only way to fully test seals under the sink. It fills all the tube under the sink with maximum pressure and vibration during the test. Many skip or miss this step of leak testing. As for hand in the disposal, the blades aren't sharp but will easily remove flesh. Fortunately they are at the very bottom of the unit. Reduce chances of injury by at least turning off power at switch, if not breaker; or preferably discount power to it by unplugging or undo wire nuts.

The contractor that did two of our bathrooms last year installed those flexible pipes. I knew from watching these videos that they were bad, and they argued that it was “convenient and good enough.” The plumbers they hired also did illegal work on a sewer line, so the clean out had an incorrect fitting (a T instead of a 45 degree pipe pointing toward the street). Our basement flooded afterwards, and they had to hydro-jet our sewer due to us thinking it was clogged. The jet tool went toward our house due to the incorrect fitting, breaking the toilet. Apparently, that whole sewer line was installed so long ago that the city did not even know where it went, and it had also collapsed, hence the flood. (It was an old clay line from 1909 or before.) It cut across 3 of our neighbors driveways without connecting to any of their houses, before probably connecting to the main line at the intersection. They are abandoning that line now, and installing a new sewer line under our house straight out to the street. They are also redoing all of the old cast iron under our house, because it has bowed so much that parts of it are actually at an incline! According to the city, there is another sewer line out of our house, but it does not seem like it is even hooked into our house at all, and there are questions of whether it even exists! The house was previously bought and flipped in 2002. The people who flipped it were obviously not really fit for the job: there were empty beer cans behind our drywall when the crew we hired demoed the bathrooms last year. We also remodeled another bathroom in 2019, (not from the same contractors, and that one was quality work, not unlike the work I see on this channel.) In that bathroom, there was a malt liquor bottle under our bathtub!

How about metal ptrap? Is there a problem with the rubber washer if there is a little leak coming from top nut? Thanks

I've always taped the threads. Good to see that isn't needed.

Did they spray paint the interior of this cabinet?

Always check your local plumbing code. In my state you can not connect a disposal on a tee like that. Each side has to have its own p-trap before they tie together and that discharge line from the dishwasher has to be secured to the wall or cabinet up under the sink bowl.

Try using half inch copper pipe about three inches on your rubber dw connection boot to hose tighten clamps forever never leak
