My pool has 4 Compool CVA-24T valve actuators and keep having several failures. Have an actuator for spa inflow, spa outflow, solar, and waterfall. I put the automation system in 3 years ago so it's relatively new.
My solar actuator failed twice, which I replaced both times. Thought I fixed it where the solar temperature sensor was in wrong place which caused the solar actuator to constantly turn on/off all day long. After that had no failures until a year later. Now this year my spa inflow actuator failed so replaced it and spa outflow actuator is getting flakey which is the beginning sign that it will need be replaced. By flakey mean they sporadically stop turning then after giving system a rest next day they work again until a few months later they fail permanently.
Before replacing I check the switch on the actuator, try both directions, and nothing. Even try swapping around the connectors into my Pentair automation system board to make sure it's not the automation system.
So is this common and just the cost of doing business? Just doesn't sound right that am going on 4 failures in 3 years. Are these actuators just junk and should be using a different brand? My pool guy said they are good and should just avoid the Goldline actuators. I read here that I should check the wires for 24VAC which didn't do previously and will do next time. Other than that is there anything else that I should check? Is there yearly maintenance that I should be doing on these actuators such as opening them up and lubing them (they supposed to be maintenance free)?
