T eflon Taping Instructions
 Use only new or clean PVC pipe fi
 Wrap male pipe threads with a sufficient number of layers of Tefl on tape.
Cover entire thread portion.
 Do not overtighten or tighten past thread stop in pump port.
 If leaks occur, remove pipe, clean off old tape, wrap as previously with one
to two additional layers of tape and remake the connection.
Piping
Support all piping connected to the pump.
 Use at least 2" (50mm) PVC pipe. Increase size if a long run is needed.
 To avoid stress on the pump, support both suction and discharge pipes
independently.
 Place these supports as close to the pump as possible.
 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 (2"/50mm).
 To avoid airlocking, slope suction pipe slightly upward toward the pump.
 Do not use an elbow near the suction port of the pump. Use a straight length of
pipe into the suction port.
To prevent flooding when removing pump for service, all fl ooded suction
systems must have shut-off valves in suction and discharge pipes.

Fittings

Fittings restrict flow; for best efficiency use fewest possible fittings. Avoid
fittings which could cause an air trap.

Pool Outlets

Use only non-entrapping suction fitting or double suction conforming with
the AS1926.3 standard.
