What washer do I need for sink trap?

Postby MatMatH » Wed Aug 11, 2021 12:12 pm

I have a dripping sink trap which it seems needs a replacement washer. Sink trap washer kits I've found contain the right type of washer - a flat O-ring, but the sizes tend to be 32mm or 40mm. The 32mm are a bit small and the 40mm way too big. Any idea what I should be looking for?

Hi matmath
Suggest you buy the 40mm kit cut a section out of the washer that is too big and reglue it using superglue.
