Faucet washers - flat or bevel?

[Unregistered]

I often get asked to replace washers in old faucets.

They are often in real bad shape. The one that I did today the house had been sold and when they turned on the water outside hose bib was running.

There was a chunk of rubber inside the faucet allow with a loose screw.

When I get called they are often in such bad shape that I can't tell what was there before.

My question is there an clue as to when flat or when bevel washers are to be used?

Beveled washers I use primarily when I know I cannot remove the seat or grind it and it is in bad shape.

This allows the rubber to mate inside the opening of the seat, rather than the outside surface only.


Flat washers I always use on good seats. :D

Thanks.

I thought that there might have been a different design of seat that used the bevels rather than the flat.
