Hi Bill,

Thanks for suggestion.
Not all that sharp with this stuff, so please bear with me.

What is a cut-off valve ?
Do you mean a check-valve ?

Thanks again,
Bob

Check any cut off valve in its path. Make sure they are all wide open.


Has recently in the last few weeks developed a water hammer when turning
it
such that the cold water is put On.
Water hammer only when turning On.
