Here are the specifics of our pool - it came with the house and was installed August 2005. This is our first time owning a pool.
According to the paper work left and what we can see this is what we have equipment wise:
Filter: Blue Haven C4520 Cartridge Filter
Pump: Hayward SUPER II PUMP 1-1/2hp 2-SPEED SP3010X152AZ
Booster Pump (runs waterfalls): Hayward Super II Pump 1 hp SP3007X10
Solar: Aquatherm Solar heating system on 2nd story of house
Vacuum: we had a RayVac vacuum plumbed in but it broke so we now just use a manual vacuum through the skimmer.
We have a Blue Haven Smart box that runs everything with a main timer for the filter/pump to run on high speed and a secondary timer to run low speed, or we can over ride the times and just run everything manually.
Our pool is approx. 23,000 gallons.
3 years ago, 6 months after we purchased the house (equipment would have been 5.5 years old) the pool pump motor was smoking, so we replaced it with a new A.O Smith B975 2 speed motor.
This past summer we were having problems with the timers, it wouldn't always come on and it would a lot of times just switch straight to low speed. No matter what settings we tried it would still randomly just not work or work perfect. So we figured there was something wrong with the main or secondary timers. But we couldn't find the parts anywhere and we thought we would have to replace the whole box. We were going to be out of town a lot and didn't want the pool pump not coming on at all so we found a way around it by re wiring it to just come on high speed. Seemed to fix the problem and timer would always come correctly just on high speed, of course we kept putting off working out how to fix it properly so we could use the 2 speeds.
Fast forward to a few days ago after a lot of rain we went out to pump out some water, only to have the pump come on for a second and then turn off, checked everything (impeller, leaks, leaves in vents of motor etc), still nothing. We switched over the wiring to 2 speed again to try running it on low speed, pump came on fine but a minute later it started smoking.
So now only 3 years later it looks like we will be replacing another motor.
Question I am hoping someone can guide us on, is do we pay $350 approx to replace motor and then we will have to put in another chunk of change to fix the timer issues. Now we are probably going over the $500 mark on fixing a nearly 9 year old pump. Or do we fork out the extra and get a variable speed pump which will have the timers all built in and we can get a $100 rebate, and it should save us money on electricity. Or is it possible the motor could be fixed? It seems 3 years isn't very long for a motor to last??? Or any other suggestions?
would appreciate any input. Thanks!
