Hello, my cartridge filter is leaking at the top where the clamp (locking ring) holds the lid onto the housing. Water is leaking at the hinge points of the clamp. This has been an intermittent problem since I moved into this property and inherited the pool. In the past 2 months it has leaked some days, while other days not at all. Sometimes when have I reattached the lid and locking ring, the leaking stopped. But yesterday and today I cannot get it to stop leaking quite a lot of water. I am having to top up the pool it has leaked so much. Any advice most appreciated. (I have added photos now; thanks for the suggestion @PoolStored . I do not know what the model number is. It looks old and the previous owner was not the person who installed it.)
