5.10. Drain line connection
Note
Standard commercial practices are expressed here. Local codes may require changes to
the following suggestions. Check with local authorities before installing a system.
Caution
The drain plastic connection is not designed to support the weight of the tube. The tube has
to have its own support.
Preferably, the unit should not be more than 6.1 m from the drain. Use an appropriate transformer
fitting to connect plastic tubing to the drain line connection of the valve.
If the backwash flow rate exceeds 91 Lpm or if the unit is located 6.1-12.2 m from the drain, use
31.75 mm (1¼") tubing. Use appropriate fittings to connect the 31.75 mm (1¼") tubing to the 25.4 mm
(1") NPT drain connection on the valve.
The drain line may be elevated up to 1.8 m providing 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 line is elevated but empties into a drain below the level of the valve, form a 18 cm loop
at the far end of the line so that the bottom of the loop is level with the drain line connection. This will
provide an adequate siphon trap.
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.
