*TOWER-FLO
recommends the installation of
unions and/or valves in these three plumbing
connections for ease of isolation or removal,
should it become necessary for any reason.
NOTE: All plumbing connections should follow
accepted plumbing procedures. Pipe joints
should be sealed using teflon tapes without
adhesive backings or with compounds suitable
for use with PVC and ABS plastics.
NOTE: Keep field piping tight and free of leaks.
Pump suction line leaks may cause trapped air in
filter tank or loss of prime at pump.

STEP 3. PLUMBING
A) Fabricate and install sweeper piping system in water source with holes sized according to the Sweeper Pipe
Sizing tables and formula or, if using TOWER-FLO
®
Sweeper-Eductor Nozzles, follow directions supplied with
the nozzles. The sweeper piping system should be designed so that water returning from the filter sweeps par-
ticulate matter toward the suction line to the filter which is usually installed at or near the lowest point in the
source water basin.
B) Install the pressure relief valve and the air release valve and its tubing (all shipped inside the strainer pot). Use
teflon tape on the fitting and thread them into the ports on the clear 8" filter vessel lid.
C) Install the strainer basket assembly shipped with unit onto filter unit's pump inlet*.
D) Connect piping from water source to strainer inlet*.
E) Install return piping from filter’s effluent (filtered water) valve outlet to water source*.
F) Install waste piping from backwash outlet valve to drain. The backwash sight tube shipped with the unit should
be installed in the waste line (as shown below) in a position which allows convenient observation of backwash
flow. Make certain the disposal point will handle the unit's stated backwash flow.
G) To permit drainage of filter system for winterization, add drain valve at lowest point in side stream piping.
WARNING
Field piping must be supported independently from the filter system to prevent stress and strains that might damage
or break the filter’s valves, face piping, and vessel.
