I'm having issues with my kitchen sink draining extremely slowly. I took some pieces of the pipes apart and let the water drain out, but that did not solve the problem. I then took the vent(?) piece pictured below off and noticed that the water is standing just below the rim of the pipe in the second picture. It does drain eventually, albeit very, very slowly.
Any ideas what could be causing this? Trying to avoid having a plumber come in if it's an easy fix.
If water is near the top of the fitting in your second photo, you need to snake the drain, feeding it down that opening as you crank it. You can rent a drain snake most anywhere.
Do what XSleeper recommended. Your drain line is clogged and water has backed up to your air admittance valve (AAV). Pour down the drain products very rarely work and in your situation the clog is an unknown distance away. So, snake/auger out the line to clear the clog. And, judging by the amount of yuck built up around your AAV I'd say this line has been running slow or backing up for a long time so the drain could really use a good cleaning out.
I get the drain cleaner stigma as I'm the King doubter of easy sounding shortcuts. But know this, my clog was over 25 feet away from the sink, I know this because my drain snake is that long and I tried it first without success. I took a chance with GG feeling that $8 was worth a try before a $100+ plumber call. I gave the sink a multi hour rest so that ALL the water had a chance to fully drain past the clog point. Poured GG directly into the drain entry followed by about two quarts of boiling water, hoping that amount would have a moment to eat away at the clog, then followed that up about 2 minutes later with about another gallon of boiling water to give it some extra pressure. In about 30 seconds I heard an incredible whoosh sound come up through the drain line when the clog got pushed downstream. I was blown away that it worked so well. Maybe I got lucky with my results, but I'll be damned, it worked.
I had rusted out tank to bowl screw so while apart I decided to install new flush valve. The rubber on it was in really bad shape. Got a new 2" flush valve. installed and put everything back together and had slow leak from tank to bowl. I lowered water level below the flapper and let it sit. The water drained out to bowl completely so the leak is not the flapper. Took apart and set tank on top of a bucket. put water in but not up to flapper. I could see it leaking under the nut on bottom of flush valve. So not good seal between the rubber cone washer and the tank hole. The hole is just slightly bigger than the washer. So cone washer barely goes into the hole. and the hole is a little rough. Ideally the hole should be about 1/8" larger in diameter so the washer seats further in but I don't know if anyway to do that. At least I would like to remove the roughness to try to get a seal. what is best way to do that? fine wet sandpaper?
Can anyone tell me how to separate the the Miele dishwasher triple filter cone base from the handle. It looks like it should just twist apart but does not.
