Bathroom basin not draining properly.

justaquestion

Hi folks,

I have one of those vanity units in bathroom and the basin on it has one of those screw in push down to seal plugs, push again to let water away.

I have noticed when I fill basin a little, say to shave, the water goes away very very slowly, I know the design of the plug probably just lets the water drain away around the sides of plug, not like the old plug where the whole drain hole is uncovered.

I have unscrewed the plug a little so that water has more room to drain, but doesn't make much of a difference.

Funny thing is if I remove plug completely and say let both taps run, than water seems to drain away normal enough.

I think the plug hole is about 35mm diameter so wonder if I can try an old style plug?

Another thing is, could it be some sort of air lock problem, or maybe waste needs to be checked for dirt?

Advice appreciated,
Thanks a lot.

Tried a sink plunger?

I had the same issue with at my last house. I replaced the bolt that secures the plug to the support for a longer piece, cut to length with a hacksaw. Sat about 0.5cm higher when up, and was fine.

I hate those drains.

Try pouring water into the overflow, if this is blocked then that's your problem, as the overflow does more than prevent the sink overflowing, it also equalises pressure before the U bend in the same way as piercing the base of a bottle makes the contents flow without "glugging".

We have a 'clicker' waste on our bathroom sink. It gets bunged up. I found the easiest way to clean it was to take it out and hold it under the running tap while operating it repeatedly and also brushing with an old toothbrush. This works for a while but it soon blocks again. I wouldn't have another. TBH we just leave it out because now we don't need the basin to hold water.
