* Problem:
We have dual tanks for well water with 268/440i controllers. One is for
an iron filter, the other a brine tank. We are running into a situation
where timers have been destroyed because the camshaft is too hard to
turn when they go to a refill cycle. (It took a while, and a couple of
timers, to figure this out.) We relieved the pressure on each tank,
checked the flappers, and couldn't see a problem. They moved very easily
while the pressure was down. Once we got the system up to pressure,
though, you really have to shove the refill valves hard to get them to
move. (First it was the iron filter, and now the softener valve has the
same problem.)
Have you ever heard of this?

* YES!!
I would think that I need to replace the flapper valves and timers, but is there something else we should look
at?
at?
* Not Flapper Valves, but the Timer and Camshaft.
We checked for obstructions, and I don't think that's the issue.
* The issue is the Timer and Camshaft.
Autotrol has Revised the Timers ( effective January 2008 ) and they have Revised the Camshafts to help prevent this very common problem.
See:
and here are the new camshafts.
Softener,
Iron Filter,
and here is the "notice" about them.
