INSTALLATION INSTRUCTIONS FOR M-PM74 PET FOUNTAIN
l An in-line PRV installed on the supply line is
recommended to ensure a working water pressure
of 40- 60 psi.
Important: Read all instructions and refer to local
codes prior to installation.
l Local soil conditions may require more gravel for
drainage.
l It is recommended to include a supply stop
appropriate located on the supply line.
Depending on code and design requirements, drain
may be open, french or sanitary connection. For french
drain place a minimum of three cubic feet of gravel
under drain opening. Local soil conditions may require
more gravel drainage.
l Piping and valve must be drained prior to being
subjected to freezing temperatures.
Refill trench and hole, compacting back fill as required.
Leave sufficient depth in hole to accommodate
concrete pour, 4” minimum recommended.
Prepare slab area surrounding fountain spreading and
compacting gravel as necessary. Prepare form
approximately 6” diameter to protect supply and waste
stub outs. Protect exposed valve assembly, tubing and
tube openings to prevent damage to equipment or to
prevent tubes from becoming filled with soil or debris.
Then pour concrete, ensure concrete is flat and level.
Prepare trench for water supply lines and waste line (if
required). At fountain location prepare hole to trench
depth and large enough for a person to work in. Lay
supply and waste into trench and above ground
allowing extra line to be trimmed during hook up, refer
to details for roughs.
l Supply line must be flushed of all foreign materials
such as pipe dope, chips, etc.
l A water filter should be installed on the supply line if
sediment or mineral content is a problem.

NOTE: FITTINGS AND TUBE SHOULD BE KEPT
CLEAN, BAGGED AND UNDAMAGED PRIOR TO
INSTALLATION.
2. Pull on the fitted tubing to ensure it is secure. Tube

connection assembly prior to leaving the site to ensure
there are no leaks.
DISCONNECTING THE TUBE:
To disconnect the tube from the fitting ensure that the
water line is depressurized. Push collet square towards
the push-in fitting body and hold. While holding the collet
in, pull on the PE tubing to remove from the push-in fitting.
TO CUT TUBE:
Cut to fit length of 1/4” PE tubing and remove any burrs
or sharp edges. Ensure that the outside diameter is free
from score marks. Tube ends should be square.
