Typical Non-Pressurized Flow Center Installation
Non-pressurized flow centers are designed to operate with
no static pressure on the earth loop. The design is such that
the column of water in the flow center is enough pressure
to prime the pumps for proper system operation and pump
reliability. The flow center does have a cap/seal, so it is still
a closed system, where the fluid will not evaporate. If the
earth loop header is external, the loop system will still need
to be flushed with a purge cart. The non-pressurized flow
center needs to be isolated from the flush cart during flushing
because the flow center is not designed to handle pressure.
Since this is a non-pressurized system, the interior piping can
incorporate all the above-mentioned pipe material options
(see interior piping), including PVC. The flow center can be
mounted to the wall with the included bracket or mounted on
the floor as long as it is properly supported.
