Hi, I hope someone can give me advice on the location for fitting a Grundfos UPA 15/90 Home Booster Pump. I am looking to instal the pump to boost pressure to my hot water taps. I am worried that if I fit the pump on the outlet from my immersion tank, water will be pumped out of the hot water vent pipe which is in the attic about 3 metres above where the pump will be located. Any advice gratefully received.
