Neglected pool (swamp) filter replacement vs cleaning

[Johnson TX]

Hello!
I have an above ground pool that was neglected for 3 yrs. Still in the process of cleaning out the remaining sludge. There were some dead animals and the pool became a birthing center for frogs. The company that is coming to replace the liner suggests I replace the filter and the pump. As far I know it is still working, without water in the pool all I can do is turn it on and hear that its running.. My question is with all the muck, dead animals and frogs that have been in the pool is it wise to replace or just deep clean and replace the sand? Also if I just need to deep clean, how do I do it. Previous seasons the pool remained clean but when covid hit, the pool became an after thought. Any recommendations will be much appreciated!

You can use the pool cleaner head, but siphon it out of the pool on to the lawn, or garden, or wherever. You'll gag your filter with that much gunk and it ends up in the same place anyway. Then re balance your chems: CYA per gallonage chart, then chlorine.

When you crack open the filter, if the sand is still sand like, even if it's filthy/disgusting sand, it will deep clean as good as new.

Deep Cleaning a Sand Filter

This post will walk you through the anatomy of a sand filter, and then provide a video at the end for how to deep clean your sand filter. The filter used in the photos and videos is a Hayward S180T top mount sand filter. The images are of a similar filter. Obviously not all filters are...

If it's all gummed up and/or rubbery, then it's time for new sand.

The pump either works or it doesn't, once the pool is full.

Good luck and keep us posted !!!
