Service and Drain Piping:
1. Pipe water softener into the service lines. The inlet and outlet
connections of the control valve are 1” copper or PVC and are
located on the back of the valve body. As you face the timer the
inlet is on the right and the outlet is on the left. Always follow local
plumbing codes when installing our water treatment equipment.
2. If sweat fittings are used, be sure soldering is done in such a manner
as not to allow heat to reach the control valve or bypass. (If
Schedule 80 PVC is used make sure to follow the proper primer and
solvent instructions.)
3. The drain line connection is 5/8” OD or ¾” npt and is located on the
top left of the valve as you face the timer. It is recommended you
install a ¾” union on the drain line for servicing if not using 5/8 OD.
The drain line must be of adequate size to allow for full regeneration
flow.
•
The control valve drain connection is 3/4" npt.
•
Never decrease the drain piping size to below the
drain connection size.
•
Maximum drain line length is 30 feet with proper
sloping the entire length.
•
Maximum drain line height is 6 feet above the control
valve.
•
The drain line must be piped to an open air gap (See
Figure above)
•
Always follow local plumbing codes.
UNDER NO CIRCUMSTANCES SHOULD THERE BE A DIRECT
CONNECTION WITH SANITARY SEWAGE FACILITIES.
