Question about Pool & Spa

Water runs out waste line when pump is running. we have replaced the difusier section on the multiport. Old Sta-rite multi port. Not real sure if we got the section with the gasket in right. The return lines have good pressure but the new pressure gauge only shows about 5lbs.It primes good and runs good but water runs out the waste line.

If you already replaced the gasket and upon opeing the valve, it is still in the grooves, look for a crack in the valve body and/or diffuser.

Tip

Backwashing A Sand Filter with A Push/Pull Slide Valve or Multiport Valve


Lots of people are first time pool owners and pool professionals forget to teach these "newbies" about the simplest aspects of pool ownership.

One of the biggest questions we receive from new homeowners is "How do I go about backwashing my sand filter exactly?"

It doesn't matter if you have a Hayward, Pentair, Jandy, Sta-Rite or any other number of Sand Filters on the market they all utilize the same basic valves for backwashing; a push/pull slide valve or a multiport valve.


To backwash with a multiport valve:
1) Shut off pump motor.
2) Press down on valve handle, rotate valve from FILTER to BACKWASH position.
3) Roll out any backwash hose or open any waste line valves.
4) Open air bleeder assembly on filter, and turn pump on.
5) Watch pressure gauge for backpressure and hose for kinks. Be prepared to shut off pump quickly.
6) After hose fills with water, run for 3 - 5 minutes or until water runs clear.
7) Shut off pump motor and move multiport valve handle to RINSE position. Run on rinse for 15 - 25 seconds.
8) Shut off pump motor and move multiport valve handle to FILTER position.
9) Turn pump back on and note lower pressure.
10) Roll up backwash hose so the dogs use it as a chew toy.


To Backwash a sand filter with a slide valve:
1) Shut off pump motor, roll out backwash hose.
2) Twist to unlock plunger T-handle, push or pull(depending on manufaturer) the plunger 2" - 3".
3) Open air bleeder assembly on filter, and turn pump on.
4) Watch pressure gauge for backpressure and hose for kinks. Be prepared to shut off pump quickly.
5) After hose fills with water, run for 3 - 5 minutes or until water runs clear.
6) Shut off pump motor and push T-handle back down into locked position.
7) Turn pump back on and note lower pressure.
8) Roll up backwash hose.

Now you are a backwash Guru!

Which part do I need to replace to stop the leak in my Sta-Rite multi-port valve ?


I couldn't see the video, but which o ring to replace depends on where the leak is. If it is coming from the side of the valve, that would be the lid o ring. If it is coming from the top center of the valve, that would be the diverter shaft o ring. If your losing water out the waste line, that means the spider gasket under the diverter needs replacing.

I replaced the sand in the filter and had the gasket replaced. When I turn the pump on no matter what the setting all of the water comes out the waste port on the pump. I am getting very little water out...


Check your skimmer and pump basket for an obstruction that might be causing your lack of water flow to and from the pool. There could also be a restriction in your intake/return lines. Also, check for air intake in the return line (cracks or breaks). Any one of these issues could be causing problems with these sand pool filters.

The brown-green gunk sounds like algae. You stated that you have cleaned the filter. Have you taken the cartridge completely out? If not, I would suggest that you do so. Scrub the inside of the filter tank with a 4:1 bleach water mixture, only 1 part bleach. Then soak the cartridge in an acid bath, like Muriatic Acid. This will kill any algae that is in the filter itself.

You may need to vaccuum your pool to waste, get rid of some of the water and refill it. This may help get the chemicals in order.

Another idea would be to run the system continuously for a couple of days. Vaccuum to waste, not to return lines, and clean the filter when it reaches 8 to 10 PSI above start-up. You may not be running the pump long enough to properly filter water. Keep trying to get chemicals in order.

We have a Sta-rite mode P2RA50-120L, when trying to empty the pool of excess water the pump runs for appox. 30sec and then cuts out...the pool was very over full we bailed some ot the water out but it is...


If all you are doing is running your filter system to waste or backwash the fact that the pool is over full has nothing to do with it. It should run fine in either case. Your motor is likely starting to fail and as it overheats, shuts off. You may want to consider taking it to a local electric motor shop for repair or replace the motor. That motor is somewhere around $150 from most places. We sell it as well. If you would like a quote, please contact www.arrowmotor.net
