INSTALLATION INSTRUCTIONS
2. Install the Suction Check Valve provided
with the pump into the pump inlet as shown
in the pump installation instructions. This
will prevent loss of pump prime and possible
interruptions in the water supply to the house.
Remove the priming plug from the pump and
add the specified volume (See Pump Installation
Instructions) of water to the pump. Either re-
install the priming plug or install a ⅜" NPT x 2"
long pipe nipple and attach a ¼" NPT Pressure
Gauge with with ¼" x ⅜" FNPT Reducer to the
pipe nipple (Figure 5).
3. Sit the pump onto the mounting bracket
and connect pump inlet to system outlet. The
system outlet is provided with a ¾" Sharkbite
Connection suitable for ¾" Nominal Copper
Tube or Pex Tube; insertion length into Sharkbite
Fitting is 1". Additional fittings will be required
to connect the tube to the 1" MNPT threaded
connection on the pump used. Cut the tubing to
Figure 5
the length required to align the pump base with
Pump and Bypass Assembly
the mounting holes in the pump mounting bracket.
Bolt the pump to the mounting bracket.
4. With the System located as desired, install the pipe/tube from the pump discharge to the desired
location of supply to house. At the house end a tee is required to accommodate supply to house and to
System Bypass Connection. Fittings will be required to connect to the 1" MNPT threaded connection
on the pump. Fittings required may vary with pump used. The optional Bladder Tank has a ¾" MNPT
threaded connection. A tee will be required if the bladder tank is installed, otherwise an elbow may be
used at the same location. To facilitate removal of pump for service, a quick disconnect
(sharkbite as illustrated, or pipe union) is recommended on the pump side of the required System
Outlet Valve (normally open ball valve).
