NOTE: The term backflow preventer, and many other associated terms like backflow preventers, backflow prevention, backflow valve and backflow preventors, as well as the two-word versions back flow preventer, back flow preventers, back flow valves and back flow valve technically refer to "fresh water" backflow valves that prevent possibly contaminated drinking water from flowing from a building back into a public water supply.  Many people confuse the terms backwater (back water) and backflow (back flow) when they are seeking the backwater valves that we offer.  It is understandable that people call what we sell a backflow valve, but the technically correct terminology associates backwater valves with sewage and backflow valves with fresh water.

All rights reserved.

backwater-valves.com is independently owned and resells
products produced by various manufacturers and assumes no
liability for the installation of backwater valves and related products.
Check with the plumbing authority in the municipality in which your valve
is to be installed to insure that your installation is in compliance with local code,
and be sure have your valve inspected by your local plumbing inspector after installation.
Inspect your valve frequently; the Backwater Valve through its clear plastic housing top,
and the Adapt-A-Valve, by removing the gate cassette.

IMPORTANT NOTES:
Pipe end-to-end, the Adapt-A-Valve takes up 6" of run in your line
and the outlet is 1-1/2" LOWER than the inlet, so in just 6"
the level of the pipe at the outlet side needs to be 1-1/2" lower.
Pipe end-to-end, the Backwater Valve takes up 12" of run in your line
and the outlet is 5/8" LOWER than the inlet, so in just 12"
the level of the pipe at the outlet side needs to be 5/8" lower.
Depending upon the amount of slope in your line
(2% minimum is required for proper operation),
you may need to replace several feet of pipe downstream
from the valve to average out this "loss" of fall.
