Hi Inyo Team, Looking for a replacement filter for my Hayward DE 3620L filter. (43-1/2" tall & 19" dia.) Lower connection is ~13" from the base and the upper conn. ~ 18". The connections on the newer Hayward model look to be considerably higher requiring changes to the plumbing. Is the Crystal Water D.E. filter a viable replacement, #570-0036-07 as the connections are lower on the body. Please let me know if any suggestions and if you recommend the Crystal filter. Appreciate your help, Bob
