4" S-641 PVC Backwater Valve with 16AC. Sleeve.

The stepped body design places the inlet socket-end higher than the outlet, promoting the correct drop-per-foot and improving flow efficiency.

Heavy-duty Acme-threaded access lid can be removed using the end of a dimensional 2” x 4” board of correct length, to ease clean-out or repair.**

Lid and flapper are equipped with an O-ring or gasket seal, assuring a positive seal-out of sewer gasses.

Designed for horizontally-installed, low-or-no pressure gravity-flow DWV systems only. Not suitable for upward-flow vertical installations or pressurized systems.

Model S-641 includes a 16” access sleeve with cap and is available in nominal pipe sizes 2”, 3” and 4”.

**Nominal sizes 3”, 4” & 6” only.

Working Pressure, Non Shock (PSI)

  • 4.3 psi (10 ft. of head) operating pressure
