Previously posted re problem with pump for shower cutting out. Anyway got plumber who installed it back who said pressure had leaked out of little chamber on side of pump, like football deflating was example used. He put pressure back into it using my foot pump and said should be fine. Worked for one shower, second shower it stopped for few seconds and came back on, third time it lasted long enough to make sure there was plenty of shampoo in hair and then stopped. Not happy bunny having to dash back with soapy hair to piddling old electric shower. Does this explanation for what was wrong sound right? If it does then any idea why it stopped again. This shower pump has just reached its 2 yr guarantee time, mind you I contacted plumber before this time was up and first repair? was done within that time but a shower you cant rely on is no good so I want to have my facts straight when he comes back. Any help appreciated.
