Pool Filter Lock Ring Troubleshooting
The problem we hear most often with pool filter lock rings is when they become stuck. This can be due to a number of things, such as:
Cartridge Filter Still Pressurized - This is a very common issue that we come across, it is impossible to remove the lock ring while the pump is running or if the filter chamber is still pressurized. To remove the lock ring, simply turn off the pump to allow the pressure to come down naturally and try again in a few minutes. If you’re in a hurry, you can also relieve pressure from the air relief valve or from the drain plug on the bottom.
Warped Filter lock ring - Sadly there is nothing that can be done about this and the lock ring has to be carefully sawn off for you to be able to get it off. Do not attempt to use heat to soften the locking ring as it may warp your cartridge filter tank or lid, causing even more damage.
Old Unused Pool Filter - If your pool has been sitting idle for a while then it is possible that the collar and lid are being held in place by dried chemical residues. A good way to try and loosen this up is to run some water over the filter lid and the pool filter lock ring and give it a few taps with a RUBBER MALLET, yes, a rubber mallet. Do not attempt to give your pool cartridge filter a good tap with a metal mallet.
Replacing a Pool Filter Lock Ring
Replacing a lock ring is pretty straightforward, simply take out the old one and put in the new one. Some words of advice though. If you’re replacing a lock ring because of warping or damage, check your pool filter lid and O-rings for damage as well as they usually fail at the same time.
Tip: Do not overtighten your pool filter lock rings. Once they’re finger right, loosen them a bit just so that they’re snug, the water pressure and your O-rings will take care of the rest. Over tightening your lock rings can cause damage to the lid and to the filter tank itself.
