My Jandy cartridge type pool filter is leaking from a small crack just above the inlet pipe. I don't know the model number or the size of the filter. It has 4 cartridges in it. I need a recommendation on how to repair and if I should bother or should I replace it. What brand would you recommend and how do I know what size ect. I have looked on you tube and it appears that I should stay away from Jandy. I have a 10,000 gallon play pool with a variable speed pump that's about 2 years old.
