Hard to tell in the pictures, but the rubber is tapered. The washer should be touching the rubber that is the same size, the smaller part of the rubber goes up and gets forced into the sink drain.

heres the last pic. I redid it so the little (tappered end) went up into the drain and the washer squished it flat. looks good. :) thanks for noticing, that was my very first question.:)


One project completed.. another started.......that pipe is glued shut , the big black drain pipe that goes to the wall. see in pic.. theres no way to get it off without getting out a hack saw....:( the only thing i can do is leave the counter where it is. and build shelves along the side between the wall and cabinent. theres about a 6 " gap or so..

Did someone say i should call a plumber............lol........... way too stubborn to just give up:hammer::up2:....why let someone else do what you can yourself.

You could always cut it and use some slip joint fittings. Not sure about code up in BC but that is usually the easiest to use as you can take them apart to clean out P traps and fix other problems in the future.

then just cement it together? where they join, ? like one that comes down to another elbow? is that what you mean with the trap on the bottom?
