I have a Pentair solar 3-way valve that is controlled by an Intermatic actuator.
What was a drip ever few seconds has not turned into a near constant stream out through the shaft area.
While doing pad maintenance, I took the valve apart (which looked fine), used a generous amount of silicone grease on the 2 shaft o-rings and put it all back together. Seemed to basically stop it at first ... until the actuator started moving again.
If I do not install the actuator, I have no leaks at all.
It almost seems like the actuator is not properly aligned and is putting sideways force on the shaft making it leak?
The first Intermatic I got ended up having a crack internally, so the shaft would wobble and not hit the dip switches to stop the rotation. This is the replacement they sent me and wondering if there is just a design flaw with these.
Anyone else have a leaking valve problem with Intermatic actuators?
Are the more expensive actuators any better?
