Materials Needed for Drain:**

1/2” (min.) union
1/2” (min.) drain line, pipe length to be determined
**Nominal drain line and drain size should be a minimum of
1/2”. Drain line exceeding 20’ in length and/or drain water that is
expected to flow over 5’ above the height of the drain port re-
quires a 3/4” line and drain. Install, non-restrictive, check valve
in drain line, if drain water is expected to flow over 5’ above the
height of the drain port . Never restrict the backwash drain water
flow.
Drain without Restrictor 3/4” MNPT
Required and Included: Brass Drain Line Flow Control Housing
(DLFC) with 7 GPM Flow Restrictor, 3/4” FNPT x 1/2” FNPT
Warning: Do not remove Drain Line Flow Control (DLFC). Re-
moval may cause media movement up into valve causing its
failure and/or into filtered water supply causing aethetic issues.

13”
Caution:
Due to system flow rate of 22 gpm and restricted drain flow of up to
7 gpm the valve during backwash is mechanically noisy. Do not be
alarmed. However check incoming line pressure not to exceed
65psi and any restricted drain line. You may re-set backwash for
daytime automatic cycle to avoid quieter evenings.
