The problem could be with the standpipe or the laterals.

The standpipe is located in the center of the sand filter and is usually made of strong and rigid plastic. If the standpipe developed a crack, then you’ll find sand in the pool.

The standpipe is connected to 8-10 laterals at the bottom which essentially have perforations and act like sieves, allowing water to get into the pool after passing via the sand filter while preventing any sand from getting through.

However, if any lateral develops a crack, sand will pass through it and get into the pool. So, you must check the sand filter and repair or replace it in case it is damaged.

And, if the standpipe or laterals are damaged, then make replace them before repairing your sand filter. If you’re unable to fix the sand filter on your own, then you may have to get a professional to do it for you.

Pump and Filter

You can remove particles and fine debris from the pool water by making use of a combination of a pump and filter. Typically, the pool pump is run around 8 to 10 hours a day, which helps to circulate the water through the filter.

The filter is usually filled with diatomaceous earth, zeolite or sand, which helps to remove the fine particles and also chlorine odors from the water. However, a pump and filter may not be able to remove the sand and debris from the bottom of the pool.


The pool filter helps to remove debris from the water and if it becomes clogged, then it will not be able to remove fine particles and debris effectively. Ensure that the basket is emptied and rinsed out regularly.

Then, turn on the pump to backwash the filter which helps to flush the debris out, sending it into the waste pipe.

After this, switch the filter to the rinse mode for a few minutes and then close it. You must also clean and rinse the leaf trap located near the pump and then replace it. Once this is done, you can turn the filter onto the filter setting again.

However, you won’t be able to use the vacuum directly. You must turn the multi-port valve to the ‘waste’ setting to prevent the water and sand from entering the filter and getting stuck to it.

When vacuuming the pool, you’re likely to remove plenty of pool water.

So, before you begin vacuuming, you must overfill the pool and, depending on the amount of sand in the pool, you may have to add more water to the pool after you complete the cleaning process.
