My 20 yr old Jandy CL340 is leaking from the bottom so I'm in the market for a new filter. The Jandy is rated at 340 sq ft and has done a good job keeping my approx 17k gal pool clear so I'm looking at comparable filters such as the Hayward Swimclear 325 or the Pentair Clean & Clear 320 with max flow/gpm of 122 & 120 vs 127 of the Jandy. The 8 hr capacity is 58k Hayward, 57.6 Pentair, vs 61k (est) for the Jandy. Moving to the 400+ sf models is going to bump up costs by approx $200. My questions are: 1. Are the specs for the models I listed "close enough" to get similar performance of the Jandy? 2. Is one brand better than the other? I did look at the Waterway brand which much cheaper but several reviews indicated they sprung leaks pretty early in their lifespan. I could purchase a new Jandy tank and top for about $1k but then at some point, I don't know if parts will still be available. So I'm a bit conflicted with the options! Thank you all in advance for your advice!
