SERVICE BULLETIN #200
SUBJECT: Change to Filter Parts

The diameter of the hole in the OLD 340-1187 valve rotor and OLD 340-1188 valve handle has been changed. The OLD 378-1016 handle pin has been made smaller. The factory is no longer making the old parts. The parts are no longer available and will be replaced by new part numbers.

If any one of the old parts has to be replaced you will need to replace all 3.

Leisure Time does not have any of the old parts. NOTE: If you have purchased a valve conversion kit 1121-1644 or your filter is newer than 1999 you can use the new numbers and order individual parts as needed. If in doubt order the complete kit 1121-1644

Different Valve Covers for Different Filters
Although the valve covers look the same at first glance, they are different.
Your old labels may be faded but you can tell by looking at the valve positions.

A valve, generally, leaks either thru the Valve Rotor stem hole in the cover or from the backwash port. This is usually caused by grit getting in under the handle, and consequently, into the hole in the valve cover. The valve rotor stem becomes scored and then doesn't seat properly after changing valve positions.

You may be able to temporarily get by with your valve as is...if after you change valve positions "press the handle all the way down on the end and let go", allowing it to pop into place. Most times that will over come the resistance caused by the "scored" Valve Rotor (Valve Rotor is what the handle is attached to, and presses against the Spider Gasket creating a seal in all the directional chambers directing water to pool, backwash port and from the pump)
