•

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.

•

Replace disk and clean build-up from walls of

valve as necessary.

•

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.

•

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.

•

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 out-

let lines are installed to the correct outlet ports

of the valve.
