Why Is There Sand At Bottom Of Pool

by Jonathan
(Stephenville, TX)

How could I clean the sand out of the bottom of my above ground pool without having to empty it every time?





Thanks for the question Jonathan

First I need to know why you're getting sand in the pool in the first place. Is sand returning through the returns after back washing? You may need to RINSE or you might have a broken lateral(s). Have you just replaced the sand in the filter?

Is the sand greased up? You may have channeling. Are there uncommon windstorms in your area? Being that I don't have this information I can only guess as to why you're having this problem. The easiest way to get rid of sand is to either manually vacuum the sand or use a pool cleaner such as a Polaris.

Getting sand into the pool is a common problem, but it means that something is not functioning properly. If you could contact me again with a little information I'm sure I can help troubleshoot your issue.

To post a reply, or if you have a similar question, you can see your post on the Q&A page in the "Sand Filter" category.

Sand Flows Out Into Pool

by Michael
(South Africa)

We are experiencing problems with our pool since replacing the sand. Our old sand was really dirty so we decided to replace it. Ever since, when our pool is on normal filter mode a lot of sand is poured into the pool.

We have checked that the switch from backwash (etc.) to filter works properly and that everything is sealed properly. Still, the sand just keeps pouring out by the pool inlet from the pump.

Please help

Regards,

Michael




New sand will go back into the pool. The finer particles will bypass the laterals. The only thing you can do vacuum to WASTE until it settles and the filter rids itself of the smaller particles. Check the freeboard and top off the sand if needed.

Next is the broken lateral. If the filter wasn't filled 1/2 - 3/4 with water the new sand may have broken a lateral.

Last is the multiport valve. Check the spider gasket to be sure it's working and intact. Replace if needed.

Sand In Pool

by Jerry
(London, On Canada)

My Hayward sand filter is only 3yrs old. When I opened it this yr I noticed sand in the bottom of my pool after one week of clear water. It started after my second backwash that week. After reading all your blogs, I presume it's a broken lateral ? How do I test which lateral to replace?




Hi Jerry. You're going to need to remove the sand out of the filter. This can be accomplished by scooping it out by hand or using a Shop Vac, or a combination of the two. Once the sand is removed you'll be able to inspect the laterals and standpipe. It might be immediately evident which one is broken.

Unscrew the bottom drain and rinse off the laterals to remove the residual sand. This makes the job a little easier.

Unscrew the lateral and replace it. It's fairly simple but may take a few minutes to do.
