TIPS
PIPE FASTENINGS
All bathroom pipe fastenings must
comply with manufacturer's
recommendations to prevent them from
sagging; otherwise they might become
clogged from an accumulation of solids.
CURVED CONNECTORS
To the extent possible, use curved
couplings rather than elbows.
If 90º elbows are not available, use two
45º elbows to form one 90º elbow.
START WITH VERTICAL PIPING
If vertical pipes have to be installed,
they must be installed before horizontal
piping.
DIRECT CONNECT TO RISERS
If riser pipes are connected, they must
be installed as closely as possible to
pump. Horizontal pipes coming from
pump and placed in front of vertical
pipes must not be longer than
12-18 inches.
EASY ACCESS
There must be sufficient clearance
to ensure easy access to pump in
case repairs are needed. At time of
installation, a purge valve and a full flow
stop valve must be installed at the base
of every drain pipe to facilitate repairs.
DRAINAGE BY GRAVITY
Waste waters flow into the pump
assembly by gravity. There is no
aspiration. All pipes must be capable
of absolute flow by gravity (
foot). Horizontal drain pipes must also
be able to provide free flow by gravity
so that the drain may empty easily
after pump has stopped.
NO DIRECT DOWNWARD FLOW
If the point of flow into the drain stack
is located beneath the base of the
pump, a stop flow valve might have to
be installed at the highest point of the
pipe to prevent back flow from the
hydraulic seal.
MINIMUM OF 3 FEET
Pump must be installed at least three
feet from stack pipe. In this way, the
pump will operate for long enough to
prime and thus eliminate waste water.

CONNECTION TO DRAIN STACK
PIPE
All drain connections to the main stack
must be made with the appropriate
certified connector. It is preferable to
use a Y joint, as shown.
NO DIAGONAL PIPES
All pump drain pipes must either rise
directly on the vertical plane or be on
the horizontal plane, with a slight
allowance for gravity flow to the point
of draining. Do not install pipes from
the pump diagonally.
PIPING
All pipes must be copper or solvent
welded plastic. Do not use flexible
plastic piping. Elbows and joint must
be spaced at least four feet apart to
prevent pipes from colliding and
knocking.
DRAINAGE
Never drain pump directly into an open
drain, a manhole, or a rainwater
collector. This is illegal and dangerous
for public health. Only direct connections
to sanitary drains are acceptable.
FREEZING
Ensure that all drains exposed to
freezing are properly insulated and
heated. In unheated buildings, the
piping and the pump must be protected
against freezing by the use of regular
pleasure craft antifreeze or must be
completed emptied.
ELECTRICITY
Before doing any maintenance or repair
work, unplug the appliance from electric
source. The electric outlet must be
breaker protected and be equipped with
a neutral ground.
