MAINLINE ML-SF446-A TEST GATE VALVE

MAINLINE Backwater Valve, 4 in Nominal, Hub Connection, 50 psi, PVC Body, White, 9-1/2 in L

The STRAIGHT-FIT™ valve is MAINLINE latest addition to the Extendible Backwater Valve series. This is a normally closed gate automatic backwater valve design. STRAIGHT-FIT™ valves come in 4 in and 6 in(both models are now available) and have features that will make STRAIGHT-FIT™ one of the most asked for valves in the industry!. Produced in both Schedule 40 PVC and ABS, the STRAIGHT-FIT™ has a body that is extendible to whatever depth you require by simply gluing a riser of Schedule 40 (like material) pipe into the valve body and extending to ground level. The 6 in valve uses an 8 in Dia riser and the 4 in valve uses a 6 in Dia riser. This sourced on the jobsite and cut-to-size on site riser is to be capped with an air-tight cap. The normally closed gate is glued to a piece of 3/4 in PVC pipe (sourced on the jobsite and cut on site to proper length) to form a tool to extract the gate from the valve body. MAINLINE has integrated Smart-CURVE™ technology into these valves which serves as a dual function. First, this system features a "curved gate" that is designed to allow a sewer rodding snake to feed and retract without catching on the gate itself! The other added benefit is a Smart-CURVE™ cleat insert" in the body that will ease and guide the retrieval of the snake without hanging up on the body. The STRAIGHT-FIT™ also features an optional Test Gate that can be used to pressure test the system or to isolate the property for whatever purpose, non -payment of services, vacation properties, servicing etc.
