I have a pentair pool pump and it spitting sand back into the pool does anyone know how to fix this?

it is a sand filter we just purchased it last year ty

It's one of two things:
1/ The multiport's key stem gasket is history or the actual multiport's interior has deformed due to an over heat situation from either the pump running dry for an extended period or someone shutting off the pump while a pool heater was running. A visual inspection of the multiport interior will let you know.

OR

2/ The lateral assembly in the bottom of the Filter Tank has a crack in it. The laterals have small slits, that allow water, but not sand to get through. If there's a crack in them, it will be large enough for sand to pass and it'll shoot back to the pool. The remedy here is to drain the tank of water and remove the sand, replace the damaged lateral finger ( or the whole assembly), refill with sand and away you go.
Of course, it's also possible that you accidentally vac'd up sand with the filter set to backwash and then switched over to filter. That can explain it as well, since that would put the debris on the wrong side of the sand bed and I HAVE seen someone do this.

Different Types Of Swimming Pool Filters

Pool Filter and pumps are important accessories for your swimming pool. Outdoor swimming pools always become dirty as twigs and leaves fall on it frequently. Moreover, the mustard algae formation in water is triggered during humid weather. Hence, pool owners must keep the water clean through water treatments and by installing correct swimming pool filters.

You can find different kinds of swimming pool filtersin the market. Basically, you will find three different types of swimming pool filters. All of these types are efficient in cleaning water and each of them has their own unique features and advantages.

• Sand Filters- This type of swimming pool filters is very simple and uses a layer of sand to clean the water. The dirty swimming pool water goes inside the filter from one side and flows through the sand layer which purifies it. The clean water flows out from the other end of the filter. You must clean the debris from this filter on a weekly basis, so it does not get clogged.

• Cartridge Filters- The operation of this one is almost similar to that of oil filters in a car engine. The cartridge fitted inside this one contains special purifying materials. The dirty water flows inside the cartridge and the impurities are deposited in the purifying materials. The fresh and clean water comes out of the cartridge from the other end of the filter. Since the cartridge gets filled with debris it needs to be replaced after regular intervals.

• Diatomaceous- This is the most efficient one among all the three types. The tiny diatoms inside this one can clean minute debris which is as small as 5 microns in size. Naturally, this not only clears the twigs and leaves but can clean your pool from those tiny dust particles that causes bacteria formation in water.

A pool owner needs to take proper care while installing a swimming pool filter since improper installation can reduce its efficiency. You must take proper care to connect the filter with the pool pump. Checking for leakage and other technical problems should be done periodically.
