I got my NEW water system as follows
1HP self priming pump connected to the municipality water mains 1" pipe
Pressure tank 24 Liter
Pressure switch set to 50/70 psi
This system works beautifully most of the day but....
It happend few times in summer that the water main has very little water pressure (10psi) to the extend that the pump can not fill the tank and reach to 70psi to shut itself off and keeps running untill i discover that by chance and shut it off manually to keep it from burning out .
How to control this case? I do not like to reduce the setting of the pressure switch to 40/60 psi because when the water pressure in the mains returns back to its normal condition the pump would start cycling during the shower which is fine with the 50/70 setting as the pump keeps running continiously during the shower that way.
I am thinking of one of 2 solutions
1- to fix another pressure switch in parallel to the existing one with low pressures settings say 25/45 psi and change to that one electrically with a 2 way electric switch during the peak hours of the day ( could be done automatically with a 24 hours timer)
2- to fix a low pressue cut off switch in the municipality side ( pumped side) to switch the pump off to protect it thn rings an alarm to switch over manually to the low settings pressure switch
Any other suggestions?
Thank you all very much in advance
