Hi
I have just built a 1 storey house in Peru. As it is a developing country water is a real issue. We have had mains water installed, but this is erratic at best. The peruvian solution is to have an external 1000 litre tank, ours is mounted at about 2.5m, which doesn't give enough head so a booster pump is needed. I know nothing about pumps so relied on advice from the local DIY superstore, Ace Maestro. They recommended a Petrollo pump with pressure tank.
When it is switched on the pressure is perfect so pretty happy. However the thing never shuts off. Am I right in thinking the tank regulates pressure to keep it constant. The guy at the store said that it would automatically switch on and off when water was required. Do I need an external valve which operates the switch or is something not set up correctly on the tank?
When you switch the pump off excess water feeds back into the tank. I was under the impression it should cycle off and on as pressure drops. We obviously don't want the pump running constantly or cycling constantly. Basically want higher pressure water when the mains is off when we turn the tap.My spanish is not great and the installation instructions only covered plumbing and electrical wiring.
How much air do you need in the tank?, how do you fill it and how often should it cycle?
Any help would mean I could have a shower in 35 degrees heat whenever I wanted!!
Cheers
