Maybe, but they are *far* more reliable than Torbeck type ones.

Depends on your water. if lime isn't a probem, then a Torbeck will
out-last the rubber seat of a traditional ball valve.

I do live in a soft water area, though. But I'm not sure about outlast or
if that matters given a ball valve rubber can last 25 years plus. I do
know the one Torbeck I have has needed attention several times while the
ball valves seem to go on for ever.


Usually crud in the mains and easily filtered out...
