Troubleshooting and Service Checklist

Problem

Cause

Solution

Valve does not change

or cycle to next zone or

outlet.

Debris or foreign objects preventing

proper movement of stem and disk

assembly.

• Remove valve top and check for foreign objects.

Clean build-up from walls as necessary.

• Check for freedom of movement of stem and

disk assembly up and down over the center pin

in bottom of valve. Scale deposits may build up

on the pin and hold stem and disk assembly

down. Clean pin and again check for freedom of

movement.

Disk may have expanded and is rub-

bing against inside walls of body.

• Replace disk and clean build-up from walls of

valve as necessary.

Restriction of flow causing pressure

in valve to build up, preventing valve

from cycling.

• Be sure that all operating outlets are not capped

and that the flow to operating zones is not

restricted in any manner.

• The backflow of water from uphill lines may be

preventing the valve from cycling properly. If the

valve cannot be placed close to the high point

of the system, a check valve should be installed

near the valve in the outlet line that runs uphill

from the valve.

Water comes out of all

the valve outlets.

Stem and disk assembly not seating

properly on valve outlet.

• Check for sufficient water flow. A minimum of 15

GPM is required to properly seat the disk.

• Remove the valve top and clean the inside walls

as necessary to ensure that nothing is interfering

with the up and down movement of the stem and

disk assembly inside the valve.

• Make sure that the operating outlets are no

capped and that the flow to the operating zones

is not restricted in any manner.

• Replace disk if necessary.

Valve skips outlets or

zones.

This will case the valve to cycle

quickly several times, skipping one

or more zones.

• The stem and disk assembly is being advanced

past the desired outlet.

• Ensure that the correct cam for the desired

number of zones is installed and that the outlet

lines are installed to the correct outlet ports of

the valve.
