Effective October 1, 2013, Pentair Aquatic Systems’ Limited Warranty on its core products of pumps, filters, heaters/heat pumps, automation, lights, sanitizers, water features, and maintenance products will decrease to 60 days UNLESS PROFESSIONALLY INSTALLED by a QUALIFIED INSTALLER on residential installations.
Bundled equipment purchases from 3 or more different product groups (inground pump, filter, heater, heat pump, control system, automatic cleaner, lighting, or salt chlorinator) purchased on the same invoice and professionally installed at the same time, will receive extended coverage of 3-years under our limited warranty terms. You’ll note that pool cleaners, maintenance equipment, and aboveground systems are categories where the warranty period is not predicated by professional installation because of the ease of self-installation by the pool owner.
Pool owners will be required to submit an original sales receipt along with a qualified installer’s invoice indicating the installation date as proof of professional installation in order to register their products and obtain the extended warranty terms.
Below are the warranty periods by product line if professionally installed only. If not professionally installed the warranty is 60 days from date of purchase.
The Best Of Both Worlds!
Finally... the ease of a cartridge filter, with the clarity of a DE filter. It doesn't get any better than this folks. I used to have a DE filter on my pool and I always had to pay a pool guy to come clean it when it was time. I knew that cartridge filters were easier to clean so I wanted one so I could start cleaning my filter on my own. But I'm a stickler for clean water so I did not want to lose my clarity. Behold... the answer is here! This Quad De filter is the best! Spend the extra money and upgrade to this filter. You won't be disappointed.
