Replacement Tap seats - any good?

Wot replacement seats? Not come across them.

If they're the plastic things sold in B&Q, they're f'useless - to badly made to get a seal and can't, of course, be cut.

A plastic top-hat section that sits on top of the original seat ... I decided to buy one (from BnQ) so will give it a go tomorrow and report back. I don't hold-out much hope but for less than £2 it's worth a try because the (rented) bathroom will probably be be re-fitted later this year so I just need to extend the tap's life for a few months.

This sort of thing?

They're crap!

I briefly considered turning-up a brass insert but thought I'd have a go at replacing the tap first ... it was a bit of a bu&&er but nowhere near as bas as I had expected.

I used them successfully about 30 years ago. That was probably the last time I had a tap which could take them.

The other important aspect of them is that they change the position at which the washer seals on the seat, which in my case meant the bit of screw thread on the tap which had worn out and jumped threads was no longer being used.

You could also get valve seat grinders which regrind the seat surface, and I still have one of those knocking around somewhere.
