I installed a new, larger Hayward cartridge filter to replace the old single cartridge bullet style filter. The old filter was undersized to the pump. The equipment is over 30' from the spa and including the run through the heater, it is a total of 50' that the water must travel. Because a high head pump is required in this application, I matched the filter based upon its flow rate to the pump. I replaced the old pump with a new Hayward, Super II and put down a new concrete pad for the DE filter to sit on, so the pump and filter were no longer crowded on a single pad. The A & A floor head valves were also replaced for the swimming pool and the spa. New Jandy valves were put in in the return lines, to replace the rotary style valves. Jandy valves can be rebuilt and the O-rings can be replaced if they leak.
This was a big job, but it was worth the effort. Replacing the floor head valves and all the floor heads at the same time, gives this customer a lifetime warranty on the floor heads and the gears in the valves. She simply needs to go to A & A's will call pick up in Phoenix and replace those parts for free as long as she owns the house.
