Project Dry Basement

Project Dry Basement

DOSD's new sewer backflow prevention program, known as Project Dry Basement, began in July, 2004. This program will cover the cost of an approved backflow prevention device for single and two-family homes in Columbus that have experienced sewer backups from surcharging of the public sewer system during wet weather or blockages. After reporting the basement backup, if your property is verified to be eligible, you will receive an application in the mail. For information about the program, please view the Project Dry Basement fact sheet (PDF file using Adobe Acrobat Reader).

Backflow Prevention Device Maintenance Information

The manufacturer of the Jay R. Smith Manufacturing Company provides the following recommended maintenance for their backflow prevention valve. Please follow these instructions:

Manufacturer recommends once a year the homeowner manually open and close the valve three (3) or four (4) times to exercise the bellows in the valve housing. This is accomplished by inserting the maintenance T-handle through the hole located in the center of the top of the valve cover and attaching to the threaded stem located on the top of the counterweight top. Once attached, pull the handle up slowly until it stops. Release the handle and allow it to return to the original position. Repeat this action for three (3) or four (4) cycles.

The manufacturer of the Mainline Backflow Products backflow valve advises periodic inspection and cleaning (monthly is suggested) of their product. Please follow these instructions:

Remove the lid cover from the pit.
Unscrew the four inch round cleanout plug on the top of the valve box and do a visual inspection.
Shine a flashlight or trouble light into the hole to see the valve body.
Inspect for debris build-up on the body, gate and beneath the gate.
If debris build-up is found, flush clean with a water hose and sprayer.
Ensure gate freely moves up and down.
Reinstall cleanout plug (do not over tighten) and pit lid cover.
