I actually have two problems
First my main pool pump, Pentair SuperFlo 1.5HP (model number: 300097) @240 volts is acting funny. It starts and runs the filter (recently backwashed) up to 5 lbs of pressure and then shuts down. Some experimenting with a volt meter shows one side of the 220 at 110 volts and the other dead. Did some more experimenting and it looks like the dead side is tripping one of the breakers. I think half of the pump is dead and needs to be replaced.
The other problem is with an old Hayward Super Pump SP2600 (2 HP) @240 volts was just humming when I tried to turn it on. Now it's completely dead. Tried to remove the motor but a couple bolts are frozen on. This is an original from when I bought the house 14 years ago so I think it's time to replace to replace the whole setup.
The pool and spa are separate systems.
Oh, and the Compupool chlorine generator for the pool won't turn on. I think this may be because the breaker on the 240 line keeps blowing and it needs 240 volts to work.
Any insight into what might be going on with the pool would be helpful. I live in Dallas, Texas and it's hot down here so I don't think the water will last long before it starts turning green. I'm thinking a new motor is in order for the pool. I have a second pump on the spa (no filter) that I can run for a while until I figure out what do do there.
