Hi all, My filter pump setup are pretty old now, the valve leaks when back washing and it just lets alot of sand/dirt through the filter. I can vacuum one day and the next it will look pretty bad. I think i may have damage to the laterals and or to big of pump(1.5hp). Its a 27' agp about 17000 gal. I was thinking of getting a new filter/pump and I saw the cartridge filters would filter better. Anyone have a hayward xstream? how much more maintenance and trouble is it compared to a sand filter. Is the 1500 big enough for my pool? I saw a bunch of post about a vibration issue but it looks like an updated filter came out that seals against the lid better. All post were from 2012-2014 it seems like. Planing on a 1.5 2 speed pump. Thanks in advance
