Newer tanks use a precharged internal bladder to provide a reserve cushion. The tanks were mounted vertically and a 'Snifter Valve' mounted midway up the tank injected a small amount of air into the tank when the pump started if the internal water level was above the snifter valve. to give a reserve capacity and reduce short cycling. If your flow rate under normal usage will exceed the pumps flow capacity at the working head, consider a larger storage tank.Įarly pressure tanks used an air cushion. In one sad case, the first repairman simply replaced the burned out pump without replacing or repairing the tank bladder. In both cases, the pump motor had burned up due to rapid repeated starts. In both cases the bladder in the tank had failed and the pump was short cycling on the pressure switch. I have serviced several installations which looked identical to the QB 60 pump mounted on a pressure tank similar to the one I linked to. A centrifugal pump of that small diameter may not be physically capable of producing anywhere near the rated head. 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. The pump can be connected to the mains electrical supply through 10amps or MCB.My off grid house is supplied with water from a tank about 6m above the shower head. The pump can be connected directly to the mains electrical. Scala2 is close coupled to an integral water-cooled motor incorporating current and temperature motor protection. It is an ideal solution for consistent and reliable pressurised water supply in the majority of domestic installations. SCALA2 is an extremely high technology product that provides exceptional performance and once installed is entirely unobtrusive in its operation. Simple to use control pad with pressure adjustment and alarm indicator lights.
