We use automatic fill valves on all systems over here.
They do require a dual check valve installed upstream of them.

As for - if you have a leak - well the system will keep re-filling and cause more damage.

As far as I am concerned, the damage would be the same as cold or hot water supply leaking.
Most systems are installed so as not to leak.

Alright, so you just use stuff like this on commercial systems but not domestics?! We use them on both and it has to be installed.

That's an expensive piece of kit to have to fit to every installation. I may have been ripped off but the last RPZ valve I had to buy cost over £200! A bit expensive for a filling loop when a double check valve is all that's required by our regs (and a disconnectable hose linking the systems).

Its an auto fill valve with an air gap built in. commercial use mostly

An RPZ valve alone can't work as an auto fill valve though, right? If it can is it set to only let water through from the mains if the pressure down stream drops below a set point?

I was under the impression that it was just a fancy verifiable check valve with a dump valve that opens in case of loss of mains pressure protecting the mains supply?

Maybe there is more to them than I understand?

The one in the link has a pressure reducing valve also

You like mocking me off all the time ? Does it give you a certain pleasure? It ain’t easy in a second language. If you want you can try a little german

Everything will come with time, no one fell from the sky and knew plumbing inside out. Let me tell you, you do mistakes too but perhaps you won’t mention them on here. None is flawless, as long as I am willing to learn and open for knew things I will be a decent plumber trust me
