Inlet Water Plumbing
A “T” or Cross Fitting with cap or plug (Not Supplied) should
be installed at the System Inlet. This fitting can be used for
draining and sanitizing the system and downstream plumbing
(Figure 5a).
Before connecting the fitting to the System Inlet, the plumb-
ing to the system must be flushed clear of all debris. Hold a
bucket at the inlet water line and slowly open the Inlet Water
Valve. Allow the pipe to flush until all debris is removed.
