Mandatory
Waste connections or the drain outlet shall be designed and constructed to provide
connection to the sanitary waste system through an air-gap of 2 pipe diameters or
38.1 mm (1½"), whichever is larger.
Caution - material
Risk of damage due to lack of gap !
Never insert the drain line directly into a drain, sewer line or trap. Always allow an air
gap between the drain line and the waste water to prevent the possibility of sewage being
back-siphoned into the softener.
5.11
Overflow line connection
In the event of a malfunction, the brine tank overflow fitting will direct "overflow" to the drain
instead of spilling on the floor. This fitting should be on the side of the brine tank. Most brine tank
manufacturers feature a pre-drilled hole for the tank overflow connector.
To connect the overflow line, locate the hole on the side of the tank. Insert the overflow fitting into
the tank and tighten with plastic thumb nut and gasket as shown below. Attach a 25.4 mm (1") I.D.
tubing (not supplied) to fitting and run to drain.
Do not elevate overflow higher than overflow fitting.
Do not tie into the drain line of the controller unit. The overflow line must be a direct, separate line
from overflow fitting to drain, sewer or tub. Allow an air gap as per drain line instructions.
