currently have a pentair nautilus fns 48- about 15 years old
pool is a approx 28K gallons
starting to wear away plus has been leaking from the bleeder screw at various time.
I guess right now it works but needs a bleeder screw, o-ring and a pressure gauge (original markings are barely visible)
what filter would anyone recommend? should I just fix the bleeder valve issues till the whole thing fails? I guess these will last 20 years?
