Re: Rainsoft timing out of sync
4. Gets stuck halfway between 'Brine Draw/SR' and "Backwash' positions for a few minutes, which is absolutely not normal, then goes to 'Refill.'
Maybe the piston is jammed. So I removed the head from the tank. Tried to get the piston to the 'Refill' and 'Service' positions by pulling the piston upwards but it won't budge. Opened the nearest service faucet to lessen the pressure in the tank and the piston easily budged. At this point, I don't know what is wrong. Somebody clue me in.
I thought about isolating the problem by taking the control unit (head) inside the house and plugged it in. Manual regend...then same thing happened. So it's not the piston. I suspect the 2 micro-switches that are located in the main drive gear are not in sync with the 2 switches in the backwash/salt dosage dial, or vice versa. Is there any way to correct this?
At the 'In-Service' position, the 'hump' on the main drive gear is aligned with the 'gap' in the brine gear -- is this normal?
You're lucky you couldn't pull the piston out, you would have had water going everywhere!
You should have a separate brine valve, it is probably sticking. It will be where the brine line attaches to the control valve and a cam wheel pushes it down. That is in the power head.
If you end up buying a new valve, the Clack WS-1 piston, seals and spacers design got rid of that brine valve. The 2510 has the same type brine valve you have now.
The "hump" is aligned right.
