Teflon Taping Instructions
• Use only new or clean PVC pipe fittings.
• Wrap male pipe thread with one or two layers of teflon tape, winding
tape clockwise as you face the start of thread. Cover entire thread por-
tion of pipe. See Figure 6.
• If leaks occur, remove pipe, clean off old tape, rewrap with one to two
additional layers of tape and remake the connection.
• NOTICE: Support all piping connected with pump! See Figure 7.
Piping:
• Use at least 1-1/2" PVC pipe. Increase size if a long run is needed.
• If large than 1-1/2" pipe is used, then use a pipe reducing fitting at the
pump/trap ports to match the pipe size.
• To avoid strains on the pump, support both suction and discharge pipes
independently. Place these supports near the pump. See Figure 7.
• To avoid a strain left by a gap at the last connection, start all piping at
the pump and run pipe away from the pump.

• Never use a suction pipe smaller than pump suction connections.
• To avoid airlocking, slope suction pipe slightly upward toward the
pump. See Figure 8.
• NOTICE: To prevent flooding when removing pump for service, all
flooded suction systems must have gate valves in suction and discharge
pipes.
• Plastic pipe will expand and contract as the temperature changes. To
allow for this, use an expansion joint or flexible piping.
• Unions are provided. Use as follows for leak-free connection to pump:
1. "O" Ring and sealing surfaces must be clean.
2. Assemble handtight only! (NO WRENCHES!)
3. NO pipe compound or Teflon tape on unions.
4. Bond pipe to unions with PVC cement.
Use PVC cement only in a well ventilated area away from flame;
FOLLOW MANUFACTURER'S INSTRUCTIONS!
Fittings:
• Fittings restrict flow; for best efficiency use fewest possible fittings.
• Avoid fittings which could cause an air trap.
• Pool and spa fittings must conform to International Association of
Plumbing and Mechanical Officials (IAPMO) standards.
• Use only non-entrapping suction fitting in pool or double suction (skim-
mer & main drain).
