Backwash Valve Installation and User’s Guide
Valve Care
Proper care and valve maintenance will add many years
of service to the pool. The service life of the valve is
determined by factors such as dirt, heat, weather
exposure, etc.
Follow the suggestions described in this section to
maximize the life of the valve.
Maintenance
Winterizing
1. Consult your filter operation and user’s manual
for winterizing instructions.
2. If possible, remove, clean and lubricate the
O-rings and diverters as described on page 3.
3. Store the parts in an airtight container or sealed
plastic bag that protects from light and air.
4. Store away from heat.
Note: If the diverters will be left in the valve body
during the winter, lubricate the valve first to be
sure the diverters will actuate easily after several
months without movement.
To extend valve life, periodically inspect shaft seals and valve bore for dirt and clean as described in the Servicing section on
page 3. To extend seal life, remove diverters and lubricate periodically.
Continuing to operate a valve with damaged components could result in sudden failure of valve structural components, which
could possibly cause flooding or serious personal injury due to a sudden release of filter system pressure. Inspect and service
your valve regularly as described in this section.
1. Dirt
Dirt particles may accumulate on the seals and
can scratch the valve body during normal filter
operation and backwashing.
These scratches can accumulate on the bore
which cannot be repaired.
Replace valve or diverters when the seals can no
longer function properly from dirt accumulation
2. Heat
This valve is not damaged by temperatures found
in correctly plumbed pool and spa installations.
Heat damage can be caused by:
•฀ Improper heater installation or operation:
Heaters should be located
after the pool
filtration equipment and must have a check
valve or similar device that ensures super
heated water cannot backup into the valve
when the pump is switched off.
•฀ Circulation pump operating with no flow:
Pumps transfer heat into the water; if there
is no water flow due to a closed valve or loss
of prime, water in the pump will become very
hot and can damage any pool equipment in-
line and close to the pump.
•฀ Always be sure the system valves are open
so that water is free to flow through the pool
equipment.
3. Weather Exposure
All materials are affected to some degree by weather
exposure. Materials used in this valve are suitable
for outdoor use.
•฀ To extend valve life, protect from weathering,
especially direct sunlight.
•฀ Years of outdoor exposure can cause materials
to become structurally weakened.
•฀ Always replace valve components that show
signs of deterioration, such as cracked surfaces
and/or significant discoloration.
4. Chemical Damage
•฀ Maintain pool water chemistry properly. Pool
chemistry is a specialized area and you should
consult your pool service specialist for specific
details.
•฀ Always introduce chemicals into the pool after
water flow passes through the pool filtration
equipment.
•฀ Use only silicone based lubricants. Other
lubricants may damage valve components.
•฀ Always install a check valve between in-line
chlorinators and pool equipment to prevent
chlorine gas from backing up into the pool
equipment.
5. Lubrication
Thick silicone grease allows O -rings to glide easily
over stationary plastic surfaces. Lubrication makes
handle actuation easy and ensures seals are not
damaged when passing over internal passageways
in the valve.
•฀ Frequency of lubrication depends on:
- Frequency of actuation
- Water chemistry
- Water quality
- Water temperature
•฀ Inspect seals and the small shaft seal after three
(3) months to be sure they are well lubricated.
•฀ Valve may be reassembled and checked again
in three (3) more months.
•฀ O-rings that have been cut, nibbled out, or
twisted may be signs of inadequate lubrication.
Damaged O-rings must be replaced.
