Question about Grundfos MQ3-45 1 HP Pressure Booster Pump
I moved into a house on a rural property in January, and we live off tank water and have a Grunfos PT18 pumping all our water into the house.
The problem is, not all the time, but alot of the time my pump stays on after having a shower, the motor keeps running and restarting continuously as if it is desperately trying to pump more water through, until I go underneath my house and literally turn it off at the powerpoint, wait for a bit then turn it back on.
I am scared if I leave the motor keep going like that it will burn my pump out.
Does anyone have any suggestions on how I can fix this problem, or why it may be doing this, or is something causing it?
Thankyou in advance, from someone who has next to no knowledge about pumps!!
The pump will start and stop with a pressure switch that is mounted in the discharge of the pump. Sometimes pressure switches get sticky and won't shut off when they are supposed to. You can buy them at most hardware stores, the most common is a Square D, and you'll need to both connect it to the pipe and also to the power line and the pump motor.
