Plumbing Parts Needed
You can get a complete install kit with all the fittings and three shut-off valves.
A. The pump needs a 1” quest-fitting adapter or SharkBite® fitting, to screw into a
flange that is supplied and already mounted to the pump. The flange has a female NPT
thread. See the picture below to help visualize this. It is the brass fitting on the bottom
of the pump. It is shown with a Quest or Pex pipe compression fitting already screwed
onto it.
B. The Quest fittings or poly pipe fittings can be purchased locally at any good plumbing
store. SharkBite
®
fittings are now the connector of choice, receiving rave reviews from
our customers! These are also available from Alternative Heating and Supplies in CT.
You need 1” Pex Pipe for the main pumps to the heat exchanger.
The Pex Pipe connected at the bottom of the pump runs to the house and normally runs
to your heat exchanger (water-to-air or water-to-water).
This will also be your supply line if you have a Hydronic or radiant heating system. A
brazed-plate heat exchanger is recommended between the two systems. See end of
this section for more information on hooking up a brazed-plate heat exchanger.
You need ¾” Pex Pipe for the hot water heater, which is commonly known as 7/8” Poly
Pipe since the OUTSIDE diameter is 7/8”.
SharkBite™ fittings are
HIGHLY recommended
for installing the Pex
pipe.
