I have a pump system as follows :-
1HP self priming pump connected to the city mains
24 Liter pressure tank
pressure switch set to 40/60
My system works perfectly in 90% of the time but sometimes in very few seldom occasions the city pressure goes very law for some reason I do not know and in different times of the day as there is no pattern of it at all because sometimes in the peak hour the pressure is good and sometimes it is low at midnight when there is no demand !
When that low city pressure happens the pump of course can not shut itself off at the 40/60 psi setting the thing that results in continous running of the pump ( I fixed an indicator lamp to show pump is running ) so I have to shut it off manually and watch on the city pressure untill it is back to normal then I reconnect the pump again
I want to connect a stand-by Cistern ( 250 Liter) parallel to the existing system piping which would enable the pump to pump from it only in those few seldom times of the city low pressure to be able to switch itself off
Any advice ?
Thank you all in advance !
