Dear All
My house consists of 4 apartments , ground floor has 0.5 H.P pump feeding it with an electronic pump controller on it
other 3 apartments are fed by another 0.75 H.P pump with another pump controller on it
Both pumps are fed from the same point which is the city pipe which has very weak pressure of 15 psi max
The problem now is in the second pump , the controller would stop the pump when pressure reaches 80 psi , when you open any tap it kicks in and stay on till you close the tap then the pressure would reach 80 psi then pump stops
But since few days now I noticed the the manometer in the second floor shows that AFTER THE PUMP STOPS AT 80PSI , the pressure KEEPS INCREASING VERY VERY SLOWLY TILL IT REACHES 100PSI AND MORE WHILE THE PUMP IS STOPPING AND NO WATER USE IN ALL THE 3 TOP FLOORS AT ALL !!!
This resulted in flixible connections burst , water filter burst and leaks everywhere , a lot of damage caused by that unjustified increase in pressure of UNKNOWN SOURCE !!!
I immediately checked the city pressure and found it the same 10psi
EACH PUMP HAS A NON RETURNING VALVE AT SUCTION SIDE
PLEASE ADVISE WHAT IS THE CAUSE OF THAT SILENT SLOW INCREASE OF THE PRESSURE WHILE THE PUMP IS STOPPING AFTER REACHING ITS MAX CLOSING PRESSURE OF 80PSI
Thank you all in advance
