Hi everyone,
I'm fitting a 1.25 bar pump to provide for a shower over the bath.
The hot water tank is gravity fed from cold water storage tank in loft.
Hence the hot water tank wont take much pressure. The 22mm feed from the hot water tank is about 1 metre from the pump. I am concerned at the possibility of any momentary back pressure from the pump damaging the hot water tank. The pump suppliers discourage fitting non return valves as they restrict flow to the pump.
Are my worries on the pump back pressuring the hot water tank justified ?
Thanks
