I discovered my pump was not running (as well as timer) and found the circuit had tripped. When I flipped the breaker back and manually turned on the timer, the circuit immediately tripped. I removed the pump motor cover and disconnected the power leads, reset the breaker, manually turned on the timer and sure enough, the booster pump started to turn. There was quite a bit of carbon inside the motor housing, and I wanted a more efficient pump so I decided to go all new.
Here is my current setup:
Intermatic single clock timer
Hayward 1hp single speed
Polaris 3/4hp booster pump with light switch to turn on/off
20x40 vinyl play pool with 1 skimmer, 1 main drain and 3 returns plus dedicated booster line
Pumps are about 5 feet from pool, ground level (so about 4-5" above water line), pressure at Hayward sand filter is usually around 18-24psi
I have 2 trippers in the timer and run it about 4-5 hours day, and 4-5 night, plus anytime we are in the pool. I use a liquid chlorinator (Hasa).
I generally have the Polaris 380 running the whole time the main pump is running, unless we are swimming. Needless to say, my pool stays very clean when I keep the chlorinator topped up and manually compensate for swimmers. I have lots of trees above my pool, so I get pecans and shells (from squirrels), leaves etc all year long.
I believe I have selected a good pump, 1.25 SHP for the Pentair vs 1.1 SHP for the Hayward. From what I have read, I believe I may be able to run the Pentair on low speed almost 100% of the time, since the Polaris is always stirring up water and removing debris from the bottom of pool. If it is especially dirty, I can crank it to high for a few hours.
Does this seem feasible? Should I consider a further upgrade to a dual timer system and somehow rig it to run high speed+booster pump for a few hours, low speed the majority of the time?
