Favorite pump isolation valves?
Have to replace one of my manifolds (plastic/leaking). Think I should replace the "brute" pump feeding it as well. What is a good set of isolation valves to go with it?
The pump has to be 20+ years old -- last of the original blue Buderus pumps that got installed when new. They are Grundfos UP14-42.
Also -- when this system was installed they used "flow check" valves .... it seems that everybody now uses the pumps with the check valve installed .... correct?
