Rick, I just wanted to let you know how happy we are with the new filter, motor and sweep you installed for us. I really didn’t think the cartridge filter would work this well on our pool, especially since it has a tired old paint job over original plaster. It keeps the water crystal clear & the Waterway motor has proven to be very energy efficient running an 8 hour per day schedule. I could not be more pleased with “The pool cleaner” it works so well. In the 26 years of doing my own pool I’ve never had it so “easy”… Thank so much for your work and suggestions. Have a great summer.
