MAINLINE ML-4XA Backwater Valve, 4 in

The adapt a valve extendable backwater valve was invented because there was a need to have easy access to enable servicing of backwater valves deeper than 2 ft. The only other options were expensive and unsightly vaults or access culverts in which someone had to crawl down to service the backwater valve. Another option, which was strictly against code but done by unscrupulous persons, was to completely bury a valve with no intention of ever servicing the backwater valve. The adapt a valve not only made extendible backwater valves easy-to install, inspect and service, but with the special gate slot molded right into the body, it could easily be used for pressure testing the ground works by adding the test gate feature. Hence, the name adapt a valve - because it could be adapted to various functions.
