During my shower yesterday the pump stopped working. The Aqualisa Aquastream was installed approximately 10 years ago and has been very reliable until now and has been a great shower. I changed the 3 amp fuse in the switched socket in the airing cupboard and the fuse is not the problem. Should I be looking at replacing this with a new one, either like for like or something similar, or would a plumber first investigate repairing the shower unit. To replace it with a new Aquastream it looks like it will cost around 500 pounds plus fitting, but I wasn't sure whether repairs are sometimes viable or is it at the end of useful life? I am not sure whether to arrange a plumber visit to investigate/repair, or ask for plumber estimate to fit new unit. If replacement advised are there any similar products I should consider? Any advice would be appreciated. Thank you.
