I wonder if anyone can Help.
We are having a detached double garage with accommodation above built, heating by oil fired combi system. The mains water will be fead off the water supply to the house, which as an outside tap off before it reaches the house. Currently the pressure it just OK, however if say the outside tap was turned on then the upstairs electric shower would not recieve enough pressure to work.
So I think we need to install some sort of booster, I have seen the Grundfos pump which would be fitted to the house and one to the garage, or the Grundfos system which as a holding tank arrangment. Also I have seen a Draper similiar to the grundfos but with a smaller capacity holding tank. Which one should I have installed ?
Thanks for any help
