Leaking sink repair
 
I have a leaking sink in one of my bathrooms and I'm not sure how to fix it. I know where the leak is but I don't know how to actually get to it to make the fix, which should be really simple. The picture indicates the problem, what I don't know is if I need to take the entire assembly out to fix the leak or if there is some way to get the PVC off so I can tighten up the copper extension that is leaking. The sink is disconnected from the wall right now so its easy to get to everything.

That copper extension is called a tailpiece. You should probably pull off the j-bend part of the p-trap so that you can pull it off. You shouldn't have to use a wrench on it. Just use teflon tape about 4 wraps worth and tighten it back up to hand tight. Replace j-bend, and you're good to go, unless it's actually something else that is leaking. :thumbup:

That's what I thought. How do I get the J-bend off? I can't get my hand in there to grab the washer (?) to unscrew it and I can't get a wrench in to hold it... or does this mean I get to go buy a strap wrench?! :clap:

flat blade screwdriver
 
Place a flat blade screwdriver against the bump on the "washer" and tap the handle of the screwdriver.

It shouldn't be tighter than hand tight. Get rubber palmed atlas work gloves. Hold with one hand, loosen with the other. Righty tighty, lefty loosey.

I can't actually get my hand in the sink base to do anything with it :(

I appreciate the feedback though! I'll give it a whirl tonight in between painting and see if I can't fix it.

It might be more trouble than it's worth if it's caulked on... we usually do..

it's a single ceramic pedastal sink. that's why i was wondering if i needed to take the entire assembly out or if it could be fixed in situ. the sink is also 100% disconnected from the wall and is currently sitting in the middle of the floor.

A very small pipe wrench should fit in there. Maybe even an 8"

if the sink is off the pedestal you should be in good shape, yes?
