sink drain

I have a tight space in which I need to install an air admittance valve (AAV). The below image shows the back of the wall behind my bathroom sink that is competing with my nearby tub drain to see who can suck out the other's p-trap faster. From my review of IRC P3114, my options seem very...

Hi there, This is my first post here and I'm hopping someone can help me figure this out (I'm loosing sleep over it for 3 days already :confused: ) I replaced my sink as part of a kitchen remodel. I Went from a shallow double bowl sink to a single bowl 10 inches deep. To make matters worse...

Please bear with me - I am pretty handy but have limited plumbing experience! We just purchased a very old home to find lots of problems. Shortly after moving in, we realized our upstairs sink did not have a p-trap. The previous owners just connected the sink tail piece to the wall with a...

I have a dual kitchen sink with recently installed drain plumbing that is not draining slowly (pictures below). Prior to the new plumbing the AAV was about 10” above the top of the lateral line into the wall (where it goes to a 90° and into the slab). The disposal had no trap, it was a straight...

Hi - we are replacing our kitchen sink with an undermount that is deeper. Based on the difference in depth, I will need to lower the outlet at the wall and have a few questions: 1) When I lower the sanitary tee (probably around 3-4 inches) am I ok to just use a Fernco connection above the tee to...

Hello, I am working on adding a wet bar in my basement and have ran into some plumbing questions for proper installation. I have a floor drain near the utilities equipment which connects to the sanitary sewer and am wanting to plumb the new sink drain into it due to proximity. I don't want to...

Let me apologize in advance... I have a tendency to write long posts and I'm pretty sure this one will be no exception. About a week and a half ago, I noticed a dripping sound between the common wall for my master bathroom and guest bathroom (which we never use because the toilet needs to be...

Have a look at this pic and tell me what's wrong...Please...and what would be up to code THis is a bath sink drain. the pipe coming through the wall on the left is coming from a kitchenette sink onthe other side of the wall... I just want to know if there is any way in hell that is code, if not...

I have a push button bathroom sink drain that is stuck down. (way down, about 1/4" below the outer ring) I can not get it to release, and can not get it to unscrew while depressed. The drain and sink are only about 4 months old. Is there a way to fix this? Or do I need to replace the whole...

Just replaced an old leaking faucet on a pedestal sink and dislodged the drain body which is now leaking at the joint from the sink drain to the pipe. This is impossible for me to get access to and I can not hand tighten the nut. Is it possible to remove the pedestal base without removing the...

Have an old house, galvanized pipe drains and vents. Redoing laundry area where vent extends straight up from near floor drain across window. Framed wall and want to bring to 2" drain code, add standpipe for washer and move laundry tub to area where old vent extends. See pic. Will the assembly...

I live in an apartment and I really would like to not call my landlord for this problem. Days ago the sink began to drain water very slowly, until yesterday it kinda stopped draining it. I tried lots of grease cleaners, removed all pipes and cleaned them and they dont seem like the problem. When...

Ran into a couple issues while testing out the drain configuration I came up with for a double vanity retrofit (Note: I had to make the decision early on to split the waste line in the vanity as opening up the plumbing wall to get dedicated lines into the stack was not practical [shared wall...

Hello all, I am a long time lurker with a great appreciation for the knowledge on this forum. Most of the time my questions and concerns have been addressed by others but I thought I would ask about a situation on my home remodeling project. I had a plumber rough in a drain for an sink in my...

My wife and I just bought a home (built 1901) and are having an issue with our double kitchen sink barely draining and backing up if the faucet is on for about a minute or more. We checked to make sure there wasn't a clog. The run from the kitchen to the vent stack/main drain is 25+ feet, and...

Changing the drain and pop-up for a bathroom sink. Whoa, the hole in the bottom of the sink is not round, but rather OVAL in shape (good grief, can NOTHING be simple in this house?!). The seal from the old drain clearly shows that it has been mated (under the pressure of a locknut) into a...

I got frustrated and craaaaaammmmmmed the stopper of my bathroom sink down into the drain assembly and wow did it work! It is suuuuuppppper stuck now and moving the up/down thingy does nothing...and is even harder than it was before. Grrrrr. Believe I have what I need to put in a new one, but...
