I've got gate valves on my CH pump.
They have been there 25 years and pump has been changed 3 times without
a
problem with the valves.
Mind you I never leave any stopcock or valve so its hard open, just keep
them a fraction of a turn from the fully open position.


I replaced my cold water tank two years ago, within a year one of the gate
valves wouldn't shut off :-(


I believe somewhere (in a mythical land) it is possible to buy "proper" gate
valves (at greater cost of course). What we all buy, of course, are the two
quid ones from the sheds, which seize.

This will probably seize at £1.39:

This *probably" won't at £3.58 plus fittings:
