I strongly suggest adding a tank with a bladder such as:īTW that looks like a turbine pump. Maximum pressure may not occur at maximum flow. New here? Try reading these, they might help FAQ731-376: Forum Policies RE: Water pressure boost pump MikeHalloran (Mechanical) 10 Jan 17 22:00Ĭan you find a pumping curve for that pump? So which is the best alternative (anybody saying to compromise halfway up the hill will be asked to leave)? This is a 35l/min 35m head pump I am concerned about waterhammer when the pressure valve trips. Electrical power is not an issue there either, but it is a little more complex. Advantage of up the top is that we won't be able hear it. Advantages of by the house are that it doesn't pressurise the downhill pipe (1 inch black poly), and it can just run off an extension lead, and pumps like lots of head on the suction side.

So we need to install a proper pump somewhere between the cold water tank at the top of the slope, and the house. The shower can run at 16 l/min, there is only one shower. So we tried the pump and got some miserable pressure reading. Then we looked at the spec of the yet to be installed instant gas hot water, and it needs at least 13m of head, and the plumber thinks that 24m is a more practical target. So, first thought was to bung in one of those 120W shower booster pumps, which theoretically can belt out 9m of head. LONG BORING BIT This makes showering a rather minimal experience. My off grid house is supplied with water from a tank about 6m above the shower head.
