  • TypeOther
  • Prevents sewage backup with ASME/ANSI A112.14.1 compliance

  • Durable PVC body resists corrosion and chemicals
  • Meets ASTM D2665 and ASTM 3034 standards

Backwater Valve for 2 in. PVC Pipe

The Spears S275P is a backwater valve designed for 2 in. PVC drainage systems. It prevents reverse flow in residential and light commercial waste lines. Plumbers and contractors specify it where a simple, reliable check mechanism is required.

Rated for 120 Deg F Fluid and 43 psi Pressure

The valve handles a maximum fluid temperature of 120 Degrees F and a maximum water pressure of 43 psi. These two limits determine whether the part suits the installation. Exceeding either rating risks seal failure or body deformation.

Socket Connection Simplifies Solvent-Weld

The socket ends accept standard 2 in. PVC pipe for solvent welding. Clean, square cuts and proper primer application prevent leaks at the joint. Misaligned pipe or insufficient cure time are the most common causes of callbacks.

Questions about this item

What does the 43 psi pressure rating mean when the valve is installed in a drainage line?

The 43 psi rating is the maximum water pressure the PVC body and stem can withstand at 120 °F before risk of failure; normal gravity drainage rarely approaches this level.

Which standards govern the socket connection and material, and what do they limit in practice?

ASME/ANSI A 112.14.1, ASTM D 2665 and ASTM 3034 certify the PVC body for DWV socket fit, pressure containment at 43 psi and service up to 120 °F.

What pipe size and socket depth are required for the 2 in valve to seat correctly?

The valve accepts 2 in PVC pipe with a standard DWV socket depth; overall inlet-to-outlet length is 5 1/4 in, so allow that clearance in the line.
