Header tank overflows.
Has 4 connections
2 x 18mm mm distribution both fitted with non return valve,
1 x 15mm [pressure limited 4 bar] supply via ball valve,
1 x 18mm overflow waste discharge to eaves.
Also theres 1 x 18mm pressure releif line from cylinder cupboard which terminates over the tank. This has a jam jar suspended below it to prove its not discharging back to the tank - it's dry.
The overflow discharges - usually overnight.
The ball valve assembly has been replaced with new - more than once and with differing types to no avail - there are no obvious leaks at this point!
Still there's an overnight discharge.
HOW?? What else can possibly be wrong?
