Came across a tap with bevelled valve seat today. Luckily it didn't need re-grinding as I only have flat re-seating cutters.
But this got me thinking. And I realised this probably isn't textbook stuff any more as we come to an increasingly throw-away attitude to plumbing fittings. Hoped some of the more experienced among you might be willing to share their knowledge though.
1. The tap with the bevelled seat had standard flat washers: is this correct? It seemed to work, but still...
Also noticed most taps I have serviced (generally good-quality relics) have a raised part on the seat, presumably to decrease the surface area the washer have to seal against. But I have also come across some valve seats that are dead flat.
2. Are the dead flat seats merely ground back a long way, or are they just cheap?
3. A domed tap washer... that's just a bodge for a knackered tap?
Any experience appreciated.
