HI FLOW™ Six-Way 1-1/2 Inch Top Mount Valve Installation and User’s Guide
OPERATION
The HiFlow™ Six-Way Top Mount Valve operates under
pressure. When closed properly and operated without
air in the water system, this valve will operate in a safe
manner.
This six position valve is designed to provide all the
necessary positions required to operate, maintain,
troubleshoot and service your filter. It is provided with
six operating positions and one winterize position. The
valve is constructed of high quality corrosion-resistant
materials and when installed, operated and maintained in
accordance to these instructions your valve will provided
years of trouble free operation.
1. This valve is equipped with an external air bleeder
(item 12, page 6). Always open this air bleeder and
stand clear of the filter and valve before starting the
system pump. Leave the air bleeder open until a
steady stream of water appears.
2. The valve has a closed position. THE PUMP SHOULD
NEVER BE ON WHEN THE VALVE IS IN THE
CLOSED POSITION. If the pump is operated while
the valve is closed, the air relief system becomes
inoperative and separation of system components
can occur. Additionally, running the system with no
flow will seriously damage the equipment.
Valve Positions
FILTER: From pump, through valve downward THRU
FILTER up through center pipe to valve RETURN port
for normal filter action and vacuuming pool thru filter.
BACKWASH: From pump through valve, down through
center pipe and to valve WASTE port for cleaning
filter by reversing flow.
RINSE: From pump, through valve downward, up
through filter, up through center pipe to valve WASTE
port for start-up cleaning and resetting filter bed after
backwashing
WASTE: From pump through valve BY PASSES FILTER
and goes to WASTE port for vacuuming directly to
waste, lowering pool level, or draining pool.
CLOSED: NO FLOW - DO NOT USE THIS SETTING
WHILE PUMP IS OPERATING.
RECIRCULATE: From pump, through valve, bypasses
filter and goes to return port for circulating water
without going thru filter.
To prevent damage to the equipment
and possibly injury always turn the
pump off before changing valve positions.
INSTALLATION
The filter valve will be installed on to the filter in one of two
ways depending upon the filter and valve type:
• Clamp-style valves utilize a clamp which holds
together the flanges of the valve and filter. To install
a clamp-style valve follow the instructions below,
disregarding steps 13-15.
• Threaded-style valves utilize a large 6” buttress
thread that screw directly into the filter tank. To
install a threaded-style valve follow steps 1-3
and then proceed to steps 13-20 (disregard steps
4-12).
Note: All item numbers called out in the instructions below
refer to the item numbers given in the replacement parts
list on page 6.
1. Inspect carton and valve for any evidence of damage
due to rough handling during shipment. If carton or
any valve components are damaged, notify freight
carrier immediately.
2. After initial inspection, carefully remove valve
components from carton.
3. Be sure sand has been placed into filter, sand guide
has been removed and top of filter cleaned of any
sand or debris.
4. Ensure o-ring (item 13) is in place in groove on valve
body.
5. Open clamp (item 14) wide enough to place over the
flange on the tank and rest on the tank before the
valve is installed.
6. Place valve over opening in top of tank so that filter
centerpipe slips into bore of valve body.
7. Valve ports are labeled with the location of where
they should be connected; i.e. pump port must go to
pump discharge, waste port must go to the waste line
and return port must go to the pool return.
Orient the valve to allow the ports to be plumbed to
the proper location.
8. Press down on valve so that o-ring (item 13) is down
inside of opening of tank top.
Use caution when handling or working
around valve clamp to prevent
potential injury to fingers or hands from contact with sharp
edges.
HIGH PRESSURE: An improperly
installed valve may separate from the
filter and cause sever injury and/or property damage.
- Continue on to next page -
Air entering a filter with a poorly or improperly
closed valve clamp can cause the valve to
separate from the filter and can cause severe bodily injury and/or
property damage. (Some valve models do not have a clamp but
thread into the filter tank.)

HI FLOW™ Six-Way 1-1/2 Inch Top Mount Valve Installation and User’s Guide
9. Lift the clamp (item 14) over the tank flange and
carefully guide the clamp so that it catches both the
valve flange and the tank flange as shown in Figure 1.
10. Insert the valve
screws and nuts
into the clamp half
making sure that
the nuts are located
in the special
hexagonal retainer
slots on the clamps.
See Figure 2.
11. Begin to tighten the clamp screws with a Phillips
screwdriver. Tap around the outside of the clamp with
a rubber mallet (or similar tool) to ensure uniform
loading and proper seating of the clamp halves.
Continue tapping and tightening until the clamp ends
touch each other. Do not tighten beyond this point to
avoid damaging the screws or clamp.
12. Check to be sure o-ring (item 18), is in place above
large thread on valve body and that o-ring is lubricated.
If o-ring requires lubrication, use only silicone type
lubrication.
13. Check to be sure filter piping assembly is exactly
centered about 1-1/2” below the large threaded
opening in the tank.
14. Carefully install the valve inside the filter opening so
that the filter piping assembly slips into socket of the
valve. Slowly turn valve clockwise until the thread
engages with the thread on the tank. Continue to
turn valve until the o-ring on valve contacts the tank.
Grasp valve by the two opposing ports and tighten as
secure as possible by hand.
Note: The valve should easily thread into the filter
opening by hand, until the valve o-ring contacts
the filter surface. Failure to position the filter piping
assembly in the center of the large filter opening, can
cause the valve to not thread properly into the filter
tank.

Use of lubricants or pipe sealants
other than those recommended in
this instruction booklet may damage the valve and cause the
valve to separate from the filter, causing severe bodily injury
or property damage.
Chemical fumes and/or spills can
cause severe degradation of valve
components. Structurally weakened components can cause
filter valve or attachments to blow off and could cause severe
bodily injury and/or property damage.

15. Orient the filter and valve to allow the ports to be
plumbed to the proper location.
16. The Maximum operating pressure of this valve is
50 psi. The filter unit also has a maximum operating
pressure listed on the filter nameplate. DO NOT
OPERATE this unit above the maximum operating
pressure of the valve or the filter. Never connect the
filter and valve unit to a pump which can generate a
pressure that exceeds the operating pressure of the
filter or valve.
17. Assemble piping and pipe fittings to pump and valve.
All piping must conform to local and state plumbing
and sanitary codes.
18. Use sealant on all tapered male connections of pipe
and fittings. Use only sealant compounds suited for
plastic pipe. Support pipe to prevent strains on filter,
pump or valve.
Note: All valve internal threads are tapered except the
air bleeder connection. Do NOT overtighten tapered
thread connections.
19. Install pressure gage in 1/4” NPT port directly across
from the pump port.
20. Never store pool chemicals within 10 feet (3 meters)
of your pool filter valve. Pool chemicals should always
be stored in a cool, dry, well ventilated area.

Valve Care
The valve is a very important part of your pool equipment
and system. Proper care and maintenance will add many
years of service and enjoyment to the pool. Follow these
suggestions for long trouble free operation:
1. To clean the exterior of the valve of dust and dirt,
wash with a mild detergent and water, then hose off.
Do NOT use solvents.
2. The valve clamp used on your valve has been
manufactured with high quality corrosion resistant
materials. The manufacturing process could allow
sharp edges to be present on the parts.When working
in and around the clamp use caution to prevent
potential injury to fingers or hands from contact with
sharp edges.
3. Your valve is a pressure vessel and should never be
serviced while under pressure. Always relieve tank
pressure and open air bleeder before attempting to
service your valve.
4. Open the manual air bleeder and stand clear of the
filter/valve before restarting your pump.
Winterizing
1. Shut off pump and open the valve air bleeder.
2. Drain and winterize the pump and filter per
manufacturer’s instructions
3. Press down on valve handle and rotate so valve
pointer is on circular rib on valve top at area on valve
marked WINTERIZE.
Note: The valve should be left in this position during
the shutdown season so the valve diverter has no
pressure on the rubber seal.
Always visually inspect valve
components during normal servicing
to insure structural safety. Replace any item which is
corroded, bent or otherwise visually defective. Defective
valve components can allow the valve or attachments to
separate from the filter and could cause severe bodily injury
and/or property damage.
MAINTENANCE
Replacing the Valve Top and Diverter
Assembly
1. Shut off pump and open air bleeder to relieve all
internal pressure.
2. Set valve handle to winterize position.
3. Remove 6 cover screws (item 10).
4. Lift off valve top and diverter assembly.
Note: Valve diverter assembly has the sealing gasket
attached to the diverter. When handling the diverter
use caution to prevent the sealing surface from being
damaged during handling.
5. Clean valve body sealing surface with soft clean
lint free cloth. Inspect surface for damage such as
scratches or nicks. If surface is damaged the valve
body must be replaced.
6. Carefully lubricate the new valve top replacement
o-ring (item 6) with a silicone based lubricant and
place appropriately on valve top.
7. Place the new valve top handle in the winterize
position. Install new valve top and diverter assembly
making sure small recess on lid and small bump on
valve body are aligned. Start all 6 screws with fingers
to insure that the screw is started in the formed
thread of the valve body. Screws should be tightened
progressively by tightening diametrically opposite
screws and following a crisscross pattern. Tighten
all 6 valve top attachment screws firmly. DO NOT
OVERTIGHTEN.
Note: Valve top is attached with self-tapping screws.
The screws must be aligned properly to prevent cross
threading of the screws in the valve body.
HIGH PRESSURE: An improperly
installed valve may separate from the
filter and cause sever injury and/or property damage.
