No

however meters need to compinsate for temps. Most do.

Could your boiler from the hotwater cause anything to change the ph? Just a thought?:wtf: However my ph doesn't change from hot to cold

Nope. Should be the same as the cold water. If you have a ph pen, you'll get different readings at different temperatures. Usually the ph pen or it's calibrating solution will come with a temperature compensation chart. Always check your water at the same temps to avoid errors.
