It's a two part answer.
1) you have to filter your pool........This can be be done by day or nightl as long as you filter 100% of you water once a day or night, that's good
2) Now you know about #1 above, many filter during the night....and they run it that way so they can run it thru a fountain......as it will cool the pool up to 15 degrees over night.
Yes Most pools dont need more then between 6 and 8 hours with the filter running per day and have an automatic timer that turns the pump on and of at the times preferred.
We have a 1HP pump with the cost of electric at 7 cents per kw. It costs about $50 a month if run all the time and $30 if shut off at night.
YES THERE IS A LOT OF TRASH THAT CAN GET IN THE VALVE TO MAKE IT LEAK. YOU MIGHT BE ABLE TO CLEAN IT FURTHER I found that with the pump running, the pool water was rising as apparently the pump was pulling water out of the ground. This was with the pool water low and the skimmer plugged off in order to try to filter after a bad storm. When I shut off the pump, the pool water went down as the valve did not seat properly.
GM vehicles do not have a fuel pump shut off switch.
Chrysler does not use fuel pump shut off switch in their cars.
There is not a fuel pump shut off on any GM cars.
It does not have a cut off switch. You will have to remove the fuel pump relay or the fuel pump fuse to shut it off.
I don't think they have fuel pump shut off switch. What model?
The fuel pump for a 2000 gm. Yukon does not have an inertia shut off. If there is no fuel then the pump or pump relay could be bad.
hit the fuel pump shut off switch
Does it run for a brief period then shut off? Could be a capacitor getting ready to fail. Could be getting hot. Is it tripping the circuit breaker?
There is no such thing. The pump runs off a relay. There is a fuel pump shut off relay. If the ecm sees a fault in the system, it will shut off the pump to prevent damage or fire.
There is no fuel pump shut off on most gm but you can take the fuel pump relay out or the fuse and crank the motor to relive the line pressure.
