I do read your posts, i have said i have looked for a non return valve and only found one on the cold supply, as its looks like the cold supply pushing the hot back (mains v gravity) i was hoping to solve the problem by finding a faulty valve on the hot side which is not there, the Trevi boost shower has no internal non return valveIf you’re not going to read my posts I won’t bother helping any more.
If there never was a non return valve on the hot i'm trying to understand why this issue has occurred, it may well need one but this issue has never been a problem in the pastI do read your posts, i have said i have looked for a non return valve and only found one on the cold supply, as its looks like the cold supply pushing the hot back (mains v gravity) i was hoping to solve the problem by finding a faulty valve on the hot side which is not there, the Trevi boost shower has no internal non return valve
And there isn't one hence reviving the postI refer you to the Sunday 4:22 post; to look for nrv inside the brass body of the shower valve.
