I have just fitted a Triton 9.5kw shower upstairs. The pressure is not good and the shower is switching from hot to cold frequently. There is no water tank in the house so it runs of a rising main. Given the poor pressure can I fit a pump 1-1.4 bar to improve the pressure?
Feed to house is fully open and the shower has a standard 15mm isolater valve. The water board state that they are only responsible for the supply to the kitchen tap and that is OK. However, I am pretty sure it is less than 2.4 bar. The central heating system only builds up pressure to just over 2 bar. If I measure the pressure up stairs and it is less than 1 bar can I fit a pump?
Do you have a FULL BORE isolation valve onto the shower supply? Are your mains stopcocks (inside and outside) FULLY open?
If you have a standard isolation valve then you do not have a full bore as WHPES rightly says. Check the installation instructions for minimum pressure for shower. If you have 2.4 bar as you say, you should also have this to the shower. If not then investigate why.
No blockage to be found. Only have washing machine and that is off. Seems to be just poor pressure. The rising main tap presssure is the same as the others next door. we all have poor pressure upstairs being on top of a hill. The shower works OK in the summer and I thought a higher kw shower would solve the problem. TIA Reg
