new sink plug/strainer + sealer?

Ant555

I need to get a new sink plug/strainer for the kitchen sink.

probably this one from Screwfix

I think there is a large black washer underneath but does anyone know (or recommend) if it will benefit from a small bead of silicone around the bit at the top where the flange of the top bit sits on my sink?
Thanks

I have always used this,it unlike some other products stays flexible and has many other uses inside and out

I'm having one of those fitted on Monday. Seems to be the one to have, not expensive, can hold water in the sink, and lift the top off to dispose of waste particles.

Not sure about this one but they normally come with a thin "foam" washer and a thick black rubber washer. The rubber washer goes under the sink, between the sink and the waste fitting. The thin washer goes under the flange of the waste fitting, between the flange and the upper side of the sink. In my experience these thin washers are not much use, and I always use a "sausage" of Plumber's Mait (see post #2 above) to seal them, and throw the thin washer away.

Put the Plumber's Mait around the underside of the waste fitting flange, put in place, put the black rubber washer on the shank of the waste, fit the back nut and tighten. Any Plumber's Mait which oozes out can be scraped off (plastic scraper for preference) and any remaining traces wiped away with white spirit.

I picked up the parts last night - job for the weekend.

For info - that particular sink strainer has the large black washer for underneath but nothing between the top face of the sink unit and the 'underneath' of the top bit of the strainer. This is where I will be using the plumbers putty.

I assume I will only need to use a tiny fraction of the 750g tub though - it will then probably live in my shed for many years until I throw it away when its gone off!

Poundland and similar shops sometimes stock small tubes of silicone sealant that would do the job.

Worth trying if you have one nearby.

Or look on eBay for a small tube.

Or ask around neighbours, family or friends if anyone has some left over from a job.

We throw out the thin washer that sits above the sink and always silicon this in.


We then add a small bead of silicon on both sides of the black washer that sits underneath the sink. Have had no call backs as a result.
