Turn the square head of the plug into the sealing ring to close off pipe openings. Maximum air back pressure is the amount of pressure a plug can withstand without moving. Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.

Underground PVC Pipe Fittings for Drain, Waste, and Vent
With thinner walls than Schedule 40 fittings, these are lighter in weight and have more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines. They are also known as SDR 35 fittings. Made of PVC, they have good strength and corrosion resistance. All meet an ASTM specification and testing requirement for material quality, dimensions, and workmanship. Threaded connections can be taken apart as needed for maintenance and repair.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

To prevent leaks in threaded connections, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.
Aboveground Standard-Wall PVC Pipe Fittings for Drain, Waste, and Vent

- For Use With: Water
- Max. Temperature: 140° F
- Specifications Met: ASTM D1784, ASTM D2665
- Pipe Nipples and Pipe: Use Schedule 40 PVC Plastic
- Flanges: Use Schedule 40 PVC Plastic
These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications. Fittings are PVC, which has good corrosion resistance. They meet ASTM D1784 and ASTM D2665 specifications and testing requirements for material quality.
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
