Sump Pumps

In many cases, opening a hole in your basement floor to install a backwater valve will expose groundwater in areas with a high water table or recent heavy rainfall.

Water will not hurt the outside of a backwater valve, but can make it difficult to inspect your valve. In cases like this, a sump pit can be excavated and a sump pump installed to pump out standing water and lower the water table below your basement floor.

A sump pump is a pump used to remove water that has accumulated in a water collecting sump pit or sump crock. Water will accumulate in the sump pit when rainwater or natural ground water is higher than the pit.

Plumbing codes in most municipalities specify that sump pumps should not be connected to the sanitary sewer. A separate line should be run to the front ditch or other appropriate water course.

Pumps are Usually dependant on a home's electrical system, and some sump pumps have a battery backup. Since a sump pit may overflow if not constantly pumped, a backup system is important for cases when the main power is out for prolonged periods of time. Here are some samples of battery backup sump pumps.

Pedestal Sump Pumps & Submersible Sump Pumps

Sump pumps are available in two basic formats; pedestal sump pumps and submersible sump pumps. A pedestal sump pump's motor is mounted above the pit, where it is more easily serviced but also a bit louder when operating and more visible. The submersible sump pump is entirely mounted inside the pit, and is specially sealed to prevent water from entering its electrical circuits.

backwater-valves.com is independently owned and resells
products produced by Mainline of Canada 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 3/4" LOWER than the inlet, so in just 12"
the level of the pipe at the outlet side needs to be 3/4" 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.
