PLEASE SAVE EVERYTHING UNTIL YOU ARE SURE YOU ARE KEEPING YOUR NEW VALVE

Backwater-Valves.com offers a 30-day Money Back Guarantee. Here’s how it works:

If you think you may want to return your valve or alarm, do not use it. We inspect each valve and alarm that we sell to insure it is in brand new, working order. If your returned valve or alarm shows signs of being used, we will be unable to refund your money as we do not sell used valves or alarms and there are sanitary issues.

You must pay for all return shipping costs. Items shipped "Collect” will be refused.

Your returned valve must be postmarked within 30 days of the order date and you must first obtain an RMA (Return Merchandise Authorization) Number from us. This RMA Number should be clearly written on the outside of the box to help us match the return with your paperwork. Packages without an RMA make it nearly impossible to determine who is to be refunded.

For your own protection, you may wish to use delivery confirmation or insure the valve you are returning. If you choose not to do so, all liability is yours.

Return the valve with all original manuals, warranty cards (not filled out), etc. and any other materials that came with the valve.

Mail to:
GREG WEILAND
Backwater-Valves.com
908 N REVERE RD
AKRON, OH 44333-2338

A restocking fee of $19 per valve will be charged for all returns to cover restocking and credit card processing expenses, and original outbound shipping charges can not be refunded.

If you have any questions please feel free to email us at help@backwater-valves.com.

NOTE: backwater-valves.com is independently owned and operated and resells products produced by various manufacturers and assumes no liability for the installation of backwater valves and related products.  Please be sure to 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 your valve is inspected by your local plumbing inspector after installation is complete. Be sure to meet or exceed the 2% minimum slope requirement and to observe the laminar flow rule requiring installation no closer than 24” downstream of any branch take off.  Inspect your valve frequently (at least once every 3 months and after any condition that may have backed contaminants up to the gate). Inspect the Backwater Valve through its clear plastic housing top, and the Adapt-A-Valve, by removing the gate cassette.

backwater-valves.com is independently owned and resells products produced and manufactured by Mainline of Canada and assumes no liability for the installation of backwater valves and related products.

Be sure to 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.

NOTE: New Straight-Fit and ML-FR4 require less slope. (refer to detail pages for these products)
