I have a similar filter grid replacement question along those same lines. I have a ~15 year old Pentair FNS 60 DE filter. Grids have lasted all this time, but now I'm getting DE into the pool and the plan is to replace all the grids. Internet search comes up with this for an FNS "Plus" 60 (Pentair # 59023300):
Whereas my old filter manual calls for part 195070 that I found here:
This part is much more expensive than the first one.
A call to the merchants helpline said the 59023300 part would work....but, why the difference? Anyone out there used one of these less expensive grid kits on an older FNS model with any success? What's the difference between an "FNS" and a FNS Plus"?
Thanks in advance,
