Poor water pressure pumps don’t work All aspects of plumbing questions and answers, help, tips and information

[Aligl]

I moved the bathroom to the back the house (next room) upstairs. I put in two pumps because low pressure water area. One for shower and one for bath. They both work intermittently and I often need to get them started with a magnet! They were new pumps. In the shower the pump might start but then if you put cold on while hot in it goes cold. Have a tank downstairs. Do I need a second small tank upstairs a - is this even a thing!? Or do you think problem with both pumps (seems odd and know they were fitted correctly). I do not have a combo boiler

Hi aligl,
Please supply more information.
Is the tank downstairs a mains fed hot water cylinder?
Are all your taps mains fed?
What make and model of pumps have you fitted?

The intermittent operation of your pumps and temperature fluctuations in the shower may be due to issues like airlocks, blockages, or incorrect sizing. Ensure the pumps are functioning correctly, check for airlocks, and confirm the pumps are appropriately sized for your water demand. Installing a pressure tank near the pumps can help stabilize water pressure. Consider adding a thermostatic mixing valve in the shower to regulate temperature. If issues persist, consult a plumber
