For example, if the pump looses prime is it just a matter of minutes before the residual water is gone and the seal is running without lubrication. It varies, but the rule of thumb is no longer than 8-10 minutes.
Subsequently, what would cause a pool pump to run dry?
It can also be caused by a “suction leak,” where there is a breach in the plumbing in front of the suction side of the pump. If a pump runs “dry” for too long it can overheat, burning up the motor and generating enough steam to melt plumbing, shrink pump baskets, and destroy seals and impellers.
Then, how do you dry out a pool pump?
Pull the back cover off and separate the motor from the pump. Grab the hair dryer from the bathroom (or space heater with a fan) turn on to low heat and have it blow warm air thru the motor as best you can for a couple hours. You have to get all the moisture out of the windings.
What happens if your pool pump runs without water?
If the pump is running without water, the seal will overheat and melt, If left running without water for a long period of time, the heat generated could damage the PVC pipe and other system components.
Should there be water in pool pump?
After about 1 minute, water should be flowing freely inside the strainer box (top of pump). If water is not flowing freely in the strainer box, return to step one and repeat. Switch the diverter valve back to half way between the skimmer and main drain.
How long can a pump run dry for?
Safe Options for Dry Pumping
If you are using the pump for tank transfer and want to empty the tank, this may mean running the pump dry for a few seconds. If the pump is run dry for less than 45-60 seconds, the pump should not suffer damage.
Should pool pump always have water in it?
But the pool pump is a little different. It’s meant to function only with water inside it. It’s not just that it can get wet and not be damaged. It’s that if it’s not wet—if it’s not full of water—it’ll be damaged.
