First time plumbing in drains for new dishwasher install

[handycanuck]

I'm new here and have been a first time home owner for about a year now. In that time the only plumbing chores I have done are an install of a bathroom sink faucet (I went with a nice 3 piece high neck faucet that gives a lot more room to wash hands, etc.) and changing water filters.

So I found a good deal on a barely used dishwasher last fall and finally got around to installing it. Its a new installation so I had to alter cabinetry, plumb in its hot water supply and its drain, install new dedicated wiring and a new breaker. I went with a 20 amp breaker and 12 AWG NMD 90 run straight to the dishwasher with no other circuits as per code.

I went to Home Depot with a rough idea of what I needed to get, the wiring was easy as I had already read up on current codes for other projects. My initial parts gathering was with my plan of turning a slow left sink drain into a nice open 1-1/2" 45 degree down pipe, lowering the p-trap about 8". I ran into problems getting the p-trap lower so gave up on that idea and went with a nearly horizontal 90, like pretty much every kitchen sink out there.

Originally the sink had a pipe claiming to be 1-1/2" but was really only 1-11/32", with a 90 tee that filled half the pipe from the left sink. That silly setup would drain the right sink in around a minute but the left sink always took well over a minute to drain..and that is annoying when you have to refill a sink.

I ran into one snag: The left downpipe threads cracked apart and broke, so I had to go back to the store and get a new sink strainer. I tested the pipes for leakage, filled both sinks full and pulled their drains and zip tied the dishwasher drain hose to the sewage pipe and about an inch down from the top of the counter. Because I had to replace the strainer, the new one ended up being a little higher than I intended and it favorably has a down slope of 22:1.

Anyways, here are some photos and a quick video:

I dont understand what your question is?

Do you also understand that this is a diy forum located in the UK?

Is your DW located immediately to the right, next to the sink cabinet? Do you understand what a high drainage loop is?

Your wiring arrangements appear sound - although a plug appliance outlet would have made things easier for removing the appliance.
Romex is OK, MC is not necessary - but i dont know your local BC code.

Some codes call for Air Gaps, but its best to work to Mfr's Inst's - Miele come with back flow preventers and anti-syphon devices.

Thanks for the input. I don't have any questions, which is why you're confused about that. This forum seems like a good place to post DIY stuff, its active and not filled with pop-ups or a thousand ads. Most North American DIY sites are based off TV shows. I could not find one decent website forum, in the five minutes I searched.

My DW is located to the right side. If you look at the last photo in my post, you'll see the supply and drainage hoses, the latter does in fact have a high drainage loop. I stated this in my post. We don't require air gaps here.

Tested the dishwasher today after getting a KO clamp for its wiring box...which isn't a box yet because its cover plate is missing, so I will have to fab one up.

Your post would have been better placed in the My Projects forum (see the forums index) but it really doesn't matter. Keep posting, someone will usually help you or comment. There are people who post from all around the world on this website which makes it quite interesting.

I could see that your DW was on the right but the hoses were coming through the cabinet wall very low which sometimes indicates that the DW is located some distance away from the trap and low level waste blockages and smells might result.
