Question: What type of a warranty does Hayward offer for this filter?
Document: When I purchased my above ground pool (27' diameter round 4' deep) a cartridge type filter was included. The cartridge was difficult to clean and needed replacement once or twice a year at a cost of $100 per replacement. The pool water always looked decent but never super clean. I purchased and installed the Hayward EC50C93S Perflex 1-1/2-Horsepower Extended-Cycle D.E. Filter Pool System. Within three days my pool water looks like what you would see on a commercial.
I would highly recommend this Hayward filter for above ground pools.
This pump is great! I replaced a cartridge filter that was about 6 years old. I always had a clean, clear pool with cartridge but felt I was constantly taking filter apart to clean the cartridge. The hayward makes quick work of filtering fine debris from pool. My pool went from slightly green to crystal clear in a week with little work on my part. This is one of those items to check price DAILY if you are on the fence. I purchased in Feb. for $308 bucks!
Absolutely the best filter I've seen in its class. This DE filter worked like magic/ removed microscopic particles, cleared the cloudy, messy haze in my pool water that my old filter could not, and is a decent value. Hayward engineers/staff designed and manufactured a superb (American) product;  great customer service to back the product too. Purchased home w/ above ground 16'x32' (abt 4ft deep) pool that came with Sta-Rite cartridge filter.
Am also considering purchasing/ hooking up the Hayward CL200 chlorinator; am interested in any comments/ user community feedback on that product...
If you need a filter replacement or new filtering system and have the extra money to spend this is the best value on the market.
This works awesome. We replaced a sand filter that just wasn't doing the trick.The water was always cloudy and we couldn't get the chlorine to stay up. We spent over $1000 last year on chemicals.Our water is crystal clear now.
Filter arrived within projected time, with packing in good shape with all required parts for assembly. Filter is working well. No issues, would certainly order again in the future if I need another pool product.
This is an excellent product. Even though the pressure gauge was damaged, a new gauge was shipped overnight and it is up and working. My water is crystal clear. The new clamp used to open the filter for cleaning with a single bolt was a great improvement.
A tab in the skimmer once a week maintains the correct chlorine level. In the past I would still need to shock at least every couple of weeks in addition to the tab.This filter has saved me time and money all summer long.I'm very happy with it. Hopefully it has a long and uneventful life.
Answer: yes
