Hi. Can anyone help please? Newteam Duraspeed 2 pump fitted 4 years ago and working fine until yesterday when, after a burst main in the area, we were without water for a day. When the supply returned to the house everything was fine except the shower and sink which is fed via the pump. I can get the cold water through no problem (and you can hear the pump working) but when you turn the hot tap on, no water comes through (and no sound from the pump). I have cleaned filters in case sediment got through but suspect the interrupted water supply may have damaged the pump! Any ideas? And if I am right, can this be repaired? Thanks.
