Pentair Pool Filter Drain Plug Leaking

A leaking drain plug in a Pentair pool filter can be caused by several different things. The most common cause is an old or worn out gasket that needs to be replaced. Another possible cause could be a crack in the drain plug itself, which would need to be sealed with a strong silicone sealant.

In some cases, the threads on the drain plug may have become stripped and need to be re-tapped before it can be resealed properly. If none of these issues are present, then it’s possible that there is debris lodged inside of the filter body which is preventing proper sealing of the drain plug when tightened down. To fix this issue, you will need to clean out all debris from inside of the filter body and use new plumber’s tape around threaded connections before reinstalling your drain plug properly with new gaskets if necessary.

If you’ve noticed a leaking drain plug on your Pentair pool filter, it’s time to take action. You’ll need to replace the old plug with a new one and make sure that it is installed correctly. Doing this will help prevent further damage from occurring and keep your pool water clean and safe for swimming.

Fortunately, replacing the drain plug isn’t too difficult of a task – just be sure to follow all manufacturer instructions closely in order to ensure proper installation!
