installation Instructions - all systems - drain connections
A word about the proper installtion of a drain line. It appears simple, however if simple mistakes are made it can create
many problems associated with this or any system. Please read the instructions below to avoid any issues.
8.
Plumb rigid tubing only (PVC recommended if code applicable) directly to the 1" MNPT drain fitting.
NOTe:
wARNING:
HINT:
9.
Connect and route the drain line to a vented sewer drain with a "P" trap or some other drain location.
Installation with an air gap is required.
HIGHLY ReCOMMeNDeD: Install a non-restrictive spring check valve in drain line within the first 2' of the drain
port to prevent possible back flow. (see below when a non-restrictive spring check valve is required)
ReQUIReD:
Similar to any washing machine, this sytem must have a minumum of a 1" air
gap on the drain to prevent back flow of drain water or gases into the system
ReQUIReD:
up over 5' above the height of the drain port, or if drain line is being routed
outside, expand drain line to 1" ID and install a non-restrictive spring check
valve in drain line within the first 2' of the drain port
CAUTION:

NOTe:
CAUTION:
to prevent any back up or cross contamination into system. Be aware attics and crawl spaces can restrict air flow.
Do not enclose or cover up drain point. It would be best if you can see the water flowing from the drain line into the
drain point. (see illustration above)
INFORMATION FOR AN OUTSIDe DRAIN LINe:
Do not freeze. Do not block or bury water flow. Do not directly connect to irrigation (bubblers, drip line and/or sprin-
klers). Create a PVC drain line(s) with holes (distribution header). Drain line and surroundings must be pitched or
sloped to allow for proper water flow and drainage where drain water never sits in the line or any landscape or rain
water is allowed to create standing water at the drain line. Allow enough space (lawn, planter, water storage) to flow
and absorb 7 gpm (bath tub) for up to 23 minutes every 6 days to avoid water damage (see drain fitting flow rate for
system on page 16).
ReQUIReD FOR AN OUTSIDe INSTALLATION: A non-restrictive spring check valve in drain line within the first 2'
of the drain port to prevent possible back flow.
Make sure o-ring and grey clip are in place to secure drain fitting.
Drain adaptor can swivel.
Do not use vinyl tubing or any hose type material and clamps for the drain line.
Install a union on the drain line in order make any service or need to disconnect easier in
the future.
Air gap with proper ventilation is a requirement.
If drain line exceeds 20' in total length, or drain line flows
Never install drain line smaller than 3/4" in diameter.
Never restrict drain line or drain water flow.
Secure (clamp, tie or wire) installed drain line near drain point to prevent movement and avoid any
possible water damage.
If using a sink, floor drain or any other drain point, an air gap is required and the drain point needs
to be capable of draining water away 7 gpm (bath tub) for up to 23 minutes every 6 days to avoid
water damage. See drain fitting flow rate for system on page 16.
Ventilation, Attics and Crawl Spaces:
Backwash is needed for proper filtration and filter life
Drain water is usable for watering and other uses and does not have to be wasted.
Air gap and proper air flow and ventilation is necessary
