Your undersink setup is quite unusual. Normally you wouldn't see three independent P-traps. What's happening is that as your dishwasher drains its siphoning water out of the other traps. This allows sewer gasses to rise through the sink drains. To correct this, have your undersink area replumbed to have only one P-trap with the other drain sources ...

That does not appear to be correctly installed, it should lie flush with or below the sink surface. These strainer assemblies commonly come with 2 ring-shaped washers; one rubber and one hard plastic or fiber. Both should be placed on the underside of the sink between the strainer mounting hardware and bottom sink surface. Neither are for "sealing" purposes....

what is the best means to connect a new PVC p-trap to the existing galvanized stub out? The plan you are proposing is best (with some things to consider, see below). ...Would ...a brass waste connector ...be better?

It looks like you have 1.5" pipe reducing to 1.25" (1 1/4"). The easiest way to handle this is with a reducing coupler (example). This should be less hassle than the reducing ring (no messing with gunky threads) and you should get a better seal overall

You could also have the cleanout above the wye. But i wouldn't use a wye there anyway. I would use a san tee and trap arm over to the sink. On top of the San tee I would (if the cleanout remains on the bottom) add a St 45° that way your eliminating the illegal S trap, and can still offset over to where you need. Remember in the plumbing world a 45° ...

Pliers and screwdriver are a poor substitute for the proper tool. ( They may or may not work but are not easy to use and may result in bending or damaging the thin metal of the drain basket without getting it to turn ) The proper tool is a Drain Removal Wrench It has two ends, one small one large, with nubs that fit into the slots of the drain. It has ...

You could take a rotary tool with a cutoff disc and slice the pipe from above right below the upper flange. By cutting the flange off you should release everything to drop out below. Brace your hands well against the sink to keep the tool stable.

I've read that pouring oil, such as vegetable oil, into a drain will put a film on top of the water in the trap and that this will dramatically slow the evaporation of the water. When you anticipate that water won't be run through a drain for a long period of time, you could preemptively add oil to that drain. This might leave an objectionable ring around ...

Well you've ruled out the obvious way which is keeping the drains , traps, full of water. Next up would be using drain stoppers. Your home store has all sorts of them. I have used the white rubber stoppers many times when leaving the residence for an extended amount of time. I have also used Glad wrap over the toilet bowels to prevent evaporation of the ...

HE soap will improve the situation. But it seems the real problem you're having is the soapy water backing up into the first floor dishwasher. How is that even happening without waste water flooding the first floor kitchen? You need to get the super involved in this. There are a number of ways to prevent backflow into a dishwasher which needs to be dealt ...
