Problem still exists after pool vacuum and backwash cleaning


My neighbor had asked me to help on her pool cleaning last week, and I gave her hands out to go out there and start pool cleaning routine. As usual, I connected the one end of pool hose to the skimmer and then began vacuuming to waste. Once I was done, I put the pump valve to reset position to filter so that there is no other activity going on. However when I came back afternoon, I noticed that the drain hose line still has remaining water with trickling sounds within.

 That line is of course dragged out to the corner of the street. It looked like the water didn’t completely get pumped out, but rather it had a few minor runoff itself for those hours. Will this cause additional problems by running for so many hours? Please guide me through the right direction.

There could be a couple of reasons that lead to your problem. First off, check to make sure your spider gasket is located securely. It is important part allowing bypass, and should be set inside the multiport valve. It might have been popped off the center of the location over the time. You can reset the position by hand tightening the valve. Also check the tension of the spring attached to the handle. It could be loose or even broken. If needed, you can order this piece of parts that will sustain continual wear & tear during operation. Sometimes it is easier for you to order a set of replacement kits which will include sealant, housing/diffuser gasket, lid o-ring, and other lubricants.
The other reason could be due to a small debris that got stuck in between the gasket and the motor. In that case, you can simply shut off the pump, reset the valve and turn it on again. Or simple inspection by opening the gasket itself could reveal the cause of the issue. When you do that, make sure the groove condition to see if it’s not too much worn out.

I decided to backwash my pool the other day, but when I was done and put it back to the filter I saw water still pumped out without stopping. Is this same situation as gasket problem as above?

Sounds like it is. In most cases, you can temporarily stop a leak by putting a small threaded plug in the backwash port, and you will see the immediate result. If you have some time, go to local pool store and buy one of those repair kits and replace gasket parts. Always make sure to shut off the pump before you turn the valve. Otherwise you will have spider gaskets got blown out.

When you are taking out the old gasket and replacing with new one, make sure to clean out the groove in the pump housing system. Use a small screwdriver covered with a layer of cloth and it will always work effectively. When it comes to install a new gasket, check if the accompanying lubrication is available from the same manufacturer, or at least the same pool usage. There are common purpose lubricators with general usage, such as Vaseline, and it will make the matter worse in the future with issue of deteriorating it later on.

As a final step, check the pump pressure gauge reads between 15 and 20 psi when in operation mode.
