Had a pool repair guy come and give me an estimate of swapping out a Northstar .75 hp pump with a 1hp 2 speed. He recommended replacing my d.e. filter too since it's metal (stainless, guess) and since I had a salt generator it would eventually rust out.
Even if that's not true, I would consider replacing the filter since it's pretty old (maybe 30 years) and the long rod that holds the grids down broke in the hole where it threads. I jury rigged a tube that's wedged between the top grid manifold and lid. That seems to work fine. I forget the brand but it's 48 square inches (or feet?) and is all metal.
Considering switching to sand filtration. Amazon has the Hayward S180T for under $200.
1. is salt rusting filter just bunk?
2. if replacing the filter, would I be happy with sand? I don't like cleaning d.e. grids 2x a year.
3. Is the S180T good for a 6000 gallon in-ground pool (yes, it's tiny) with 2" lines, solar panels, a hayward vac and dual speed Northstar 1 hp pump?
4. Anyone switch from d.e. to sand and can give the pros/cons from a user's perspective?
5. do you have to backwash sand more often than sand?
6. will sand cause much more back-pressure?
wheew, thanks everyone!
