My bathroom sink drain smells. The trap is working fine but stink still comes out. Any ideas? Thanks, Mike

how about the overflow hole?

Packy:

There is no overflow hole....The mystery continues, Yikes

how do you stop the drain so you can fill the sink if needed?

I just pull the lever up.

You most likely have a drain assembly designed for an overflow sink.

It becomes a 'dead end reservoir' loaded with stagnant water.

You need a drain designed for a no overflow sink.



wrong:




right:

geesh bern.. there are countless millions of bathroom lav drains like the one label "wrong" ???

if someone changes their sink waste to the type you call "correct" then they have to plug the overflow hole. it will still collect stagnant water.

packy,


no


the posted pics may be confusing


they are BOTH pop-up drains


the second pic merely is at an angle which does not show the 'mechanism'


if one uses a 'overflow' drain then the slots for the overflow allow stagnant water to accumulate on the OUTSIDE of the drain ABOVE the 'MAC washer' INSIDE the sink AND be exposed to air (through the drain's overflow slots) AFTER the sink drains - sometimes this stinks, sometimes it does not




almost ALL the faucets sold at the big box stores offer no choice as to the type (overflow/no overflow) drain
