SOURCE: 1.5 hp waterway champion pool pump issue

Be sure you have connected the motor to the line leads correctly and that the motor is set for the proper line voltage.

A somewhat common problem is that most motors are dual voltage (can be ran on 115 or 230 volt) and come factory set for 230 volts. If you connect it to a 115 volt circuit it will run for a while and then overheat and shut off.

That means that the connection between the motor and the actual centrifugal pump is broken. This is terminal: replacing the broken part will cost you more than the price for a brand new pump. Just cut your losses and replace it.

Check to see that the pool pumps mounting is secure. Loose mounting could cause the motor to run loudly. It could be bearings rubbing or a bent shaft. If it is new, this should not have happened. If you check the mounting and feel that it is secure, I would return the pump to an authorized Waterway service agent and let them look to see if the bearings or shaft are damaged. I would do this quickly while you can still return the pump if its defective.

SOURCE: We just bought a used 22 inch waterway pump, when

you need to vacuum on waste, when the vacuum sucks down on the pool liner it will cause a high vacuum in the filter that will mix up the sand causing some of it to get washed back into the pool. if you vacuum on waste you will avoide this problem also if you have algie in the pool this will remove the algie from the filter system rather then alowing it to grow in the filter.....good luck

Your multiport spider gasket is bad. Just replace it by removing the top assembly. Remove the 6 phillips screws on the valve cover and the whole assembly will come off. This is easiest done when the valve is first put on the "Winter" position

When turning pump on sand shoots into pool app. two seconds.replaced diverter and lateral coponents. still does the same thing. twm 19 inch p/n 520-1910


If you don't have a manual you can download one here:

Are you sure you didn't damage laterals when adding sand. Best to have 1/4 water in filter as you add sand. Be sure o ring is in place in multiport valve that fits on downtube.Be sure down pipe is not too low to enter multiport valve. The pipe should fit snugly into the multiport valve o ring. Be sure you have correct sand (pool filter sand only) IF all this is ok, try backwashing till glass is clear. Run on rinse position for a few min. THen go back to filter and see if it still pumps in sand.

Sand and murky water being discharged into pool after backwash


You posted this question in Alarm category. but sounds like either your filter laterals, or the backwash valve are bad. I'd need to know what type of filter, and backwash valve you have. is the backwash valve a multiport, or push/pull slide valve, etc... If it's a push/pull valve then the o-rings, or pucks can be bad, or the piston can be broken. if it's a multiport valve, then the spider gasket may need to be replaced. if it's a top mount multiport valve, then it can be broken inside the filter.

Wicor high rate sand filter P20. When I have it on "filter" there seems to be some water starting to leak from "backwash" hose.I only let it run maybe 30 seconds. Not looking for it to blow out any seals...


If it has a multiport valve, most likely the spider gasket inside has damage or has come out of place. A broken stem spring can also cause water to bypass out the backwash due to not having enough force to seat the seal. Take the multiport apart and check the spider gasket and spring.

After vacuuming and backwashing, the dirt recycles back into the pool PSI is only 8 - what is wrong?


Assure that the o ring is positioned onto the multi-port throat correctly. That could cause dirt to recycle into the pool water.It could also be issues with the multiport valve in the pool filters.

My filter and pump will not retain the prime after turning off. Its a pantera sand filter. I can hear an air hissing sound coming from the multi valve port


Either you have a bad spider gasket inside the multiport valve or a bad threaded fitting going into it. Check for leaks around the multiport and backwash line. You'll have to take apart the multiport valve to make sure the spider gasket is not damaged or out of place. Make sure to install the multiport valve in the same position. You can get a replacement gasket at most pool supply stores or online.
