Questions about this item

Will the 3 inch S-660 ABS backwater valve connect to my existing 3 inch ABS piping?

The valve is a 3 inch ABS backwater valve designed for solvent-weld connection to standard 3 inch ABS drain pipe and fittings.

How can I confirm the flapper is sealing properly after installation?

Run water through the line and verify the flapper opens freely; then stop flow and ensure it drops back to a tight seat with no leakage past the seal.

Does the 202-273 package include solvent cement or transition couplings for other pipe materials?

The box contains the valve body and flapper assembly only; solvent cement and any transition couplings must be purchased separately.
