My gas Ariston A30MFF1 boiler has a 15mm water supply pipe to it
Is this big enough?
Behind the 15mm cold supply pipe valve to the boiler there is a copper elbow. On this elbow a 10 or 12mm stub has been soldered or brazed
Is that a standard fitting and will it be strong enough for cold water pressures?
The stub then has a valve and the filling loop on it.
Many thanks for any help
