THREADED CONNECTIONS
Use only Teflon® tape or equivalent on threaded plumbing connections. Other pipe compounds may damage
threads. Do not use silicone or petroleum based compounds. Do not over tighten. Hand tightening plus 1/2 turn is
sufficient.
PUMP PLUMBING
Suction pipe should be as large as or larger than discharge pipe. Avoid using a suction pipe smaller than the pump
connection. The pump is designed to accept 1-1/2" suction piping.
1. Keep the piping as straight and short as possible, and of suitable size.
2. Avoid connecting an elbow directly into the pump inlet. A length of straight pipe will allow proper entry of the water
to the pump.
3. Slope horizontally, and run upward to the pump to prevent trapping air.
4. Use independent piping supports to reduce strain on the pump.
5. Keep as much of the suction line as possible below the water level to reduce priming time.
6. Install valves and unions in the pump suction and return the lines to facilitate servicing. Valves are also essential
for pump maintenance, if the system is installed below deck level.
NOTICE: Use Teflon® tape or Plasto-Joint Stik for making threaded connections to the pump. Do not use pipe dope.
Teflon® Taping Instructions:
Use only new or clean PVC pipe fittings. Wrap male pipe threads with one to two layers of Teflon® tape. Cover entire
threaded portion. Do not over tighten. If leaks occur, remove pipe, clean off old tape, rewrap with one to two
additional layers of tape and remake the connection.
Fittings:
Fittings restrict flow; for best efficiency use the fewest number of possible fittings. Avoid fittings which could cause an
air trap. Pool fittings must conform to International Association of Plumbing and Mechanical Officials (IAPMO)
standards. Use only non-entrapping suction fitting or double suction.
POOL PUMP SUCTION REQUIREMENTS
Pump suction is hazardous and can trap, drown, or disembowel bathers. Do not use or operate swimming
pools, spas, or hot tubs if a suction outlet cover is missing, broken, or loose. Follow the guidelines below for a
pump installation which minimizes risk to all users of pools, spas, and hot tubs.
Entrapment Protection
The pump suction must be designed to eliminate the possibility of suction entrapment or hair
entrapment/entanglement.
Suction Outlet Covers
All suction inlet covers must be maintained and replaced if cracked, broken, or missing.
See Figure * for outlet cover certification requirements.
Testing and Certification
All suction inlet covers must comply with ASME/ANSI specifications for suction fittings for use in swimming pools,
spas, hot tubs, and whirlpool bathtub applications. The product must be tested for compliance with the standards,
and the certification must be included with the components.
