DHW booster pump flow switch failure
The flow switch on my grundfos UPA 15/90 has just failed in the on
position, I fitted it in summer 2004, so it doesn't seem long. Can I replace the switch, AtM I daren't touch it! It'll have to wait till summer. Alternatively, should I fit a separate flow sensor. Is there an economic one that will do the job - if it's an unreliable component I't rather keep replacing just the switch. And can the Grundfos switch (if I can get the part), be replaced "dry" or could a replacement flow switch be fitted dry, or could I get a separate switch where the electrics could be replaced "dry", like zone valves? Questions, questions.... Any answers, please? mike |
