1.4 • Only one vertical lift on the inlet to the
pump and the discharge from the pump
is allowed.
• When laying the pipe under the floor use
only slow radius bends.
• Use slow radius bends above the floor if
possible to ease the flow of water and
reduce loading on the pump.
• Use of copper pipe is recommended to
reduce risk of air leaks at connections.
• Ensure edges are burr-free. Burrs may
cause a build up of hair etc. that will
reduce flow.
• Pipework
must
be secured to prevent
any vibration and noise.
• Twist lock the securing ring on the push
fit fittings (If semi rigid pipe is being used
follow the manufacturers instructions to
prevent air leaks).
