    I have a caleffi valve on my system. It has worked well for some 10 years. Recently I noticed it is not regulating, with no flow sits at mains pressure. With flow it regulates. Replaced cartridge but just the same. It is a Caleffi 5350, i.e a static regulator. Any ideas as to why performance has changed?

    Time for a new one if it’s been good for 10 years
