Lots of sand? You may have a broken lateral in your filter.

To repair, you will have to remove all the sand from the tank to physically inspect.

Might you have changed the sand this year? (top 1/3 needed to be changed every 3 to 5 years normally) If you changed the sand ... did you put water in the filter tank first? If not ... there is a good possibility you broke a lateral (a small pipe with slits in it) when you put the sand into the filter.

It could be that you have too much sand in the filter. Check the owners manual for the clearance - top of sand to top of filter.

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!

Sand shooting back in pool


If you took "Pump" apart, you wouldn't have found broken laterals. You will need to open up the "Filter" to find laterals. If sand is ending up in the pool, you either have a broken component within the filter or you have an overfilled filter tank and during backwash sand is lifted up into the valve, and upon returning valve position back to "Filter" the residual is blown back to pool via the return inlet. If this is the case that is why always follow label / owners manual directions as to Quantity of media to add. More is not necessarily always better!

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.

Pentair Quad DE system was installed without multiport valve


This is a DE (Diatomaceous earth) IT doesn't have sand and doesn't backwash. You use the bump handle (with pump off and valves closed and vent open and drain dirty water/earth out) Here is a link to the manual for your filter If isn't the exact model they are all on their web site: http://www.haywardnet.com/products/Manuals/pdfs/manual9.pdf

Sounds like you have a problem inside the filter. This will probally be something you will want to get a pool guy for. If the filter is only two years old you should check for warrenty on the filter. Sorry for the bad news and good luck.
