You can't see it properly here, (although you can below), but my McAlpine sink trap has an extra spout for a washing machine hose. This could also be used for a dishwasher instead. The problem is i have a bit of a leak at this joint, even then the screw end is tightened as far as it will go the outside pipe can slide and move in/out (though to get it completely out would take a good pull).

Again, excess plumber’s putty or caulk will squeeze out from around the flange as a sign that you have a good seal. Scrap it off with a putty knife. The kitchen sink basket strainer plug for our double bowl sink had been leaking for a couple of months and it was driving me batty. It made washing up difficult because the water would drain away while washing up the pots and pans. Even more frustrating was when both plugs stopped sealing, so we couldn’t swap the plugs. It’s one of those things you don’t realise is annoying until you have to fill the sink and you can’t. But you soon forget until you need to fill the sink again! There are a handful of ways you could do this. I decided that instead of drilling a hole for another waste pipe, I linked my washing machine hose to the sink. The other end has a screw type fitting but the pipe that goes out to the drain is smaller and has no thread on it so it sort of slots over a smaller ring of the internal pipe work and then the circular plastic screw cap/head screws onto the internal pipe work. First, just for demonstration purposes, here's the bottom drain section. The pipe ideally should aim towards the overflow drain (as above).

This prevents them from clogging up the drainpipe farther away where unclogging it would be harder. If you have a pop-up bathroom sink stopper (which is the case with most bathroom sinks), you will first need to remove the stopper before you can remove the flange. This is actually a really simple task so let is get down to it.

If you decide to use silicone caulk, apply a bead of the same under the rim of the sink flange as well as around the sink drain opening. Carefully insert the flange through the drain opening and push it down strongly to get a strong seal. Clear the space under the kitchen sink.
