Drain line connection

Info
Standard commercial practices are expressed here.
Local codes may require changes to the following suggestions.
Check with local authorities before installing a system.
Mandatory
The drain line must be built with 1½" rigid piping ! An air gap must be present at the
drain!
CAUTION
Risk of injury due to whiping hose !
Flexible and semi-flexible hoses may bend and whip during draining.
The drain line may be elevated up to 1.8 m provided the run does not exceed 4.6 m and water
pressure at the softener is not less than 2.76 bar. Elevation can increase by 61 cm for each
additional 0.69 bar of water pressure at the drain connector.
Where the drain empties into an overhead sewer line, a sink-type trap must be used.
Secure the end of the drain line to prevent it from moving.
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
76.2 mm (3"), 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.
