FloPlast Ring Seal Soil Boss Pipe - 110mm

You will need a 54mm hole saw to drill out the blanked-off ports on the boss pipe.

This boss pipe is compatible with FloPlast's SP10, SP11, and SP12 rubber boss adaptors, as well as their SP20, SP21, and SP22 solvent weld boss adaptors.

The boss pipe has a ring seal push-fit socket on the top end for connecting into a socketed fitting or pipe, and a plain spigot end at the bottom to connect into the socketed end of another fitting or pipe.

Yes, the boss pipe comes with one open port and additional blank ports that can be drilled out, allowing for multiple waste pipe connections.

While designed for soil stacks which can be underground, its materials and connections are suitable for both above-ground and underground applications provided correct installation practices are followed.

Its main benefit is the flexibility it offers, with multiple blank ports that can be drilled to accommodate specific installation needs, alongside compatibility with different adaptor types.

Ensure both the soil stack pipe and the boss pipe's spigot end or socket are clean and free of debris. For socket connections, ensure the pipe is fully inserted. Lubricant can aid insertion if needed.

Verify the correct adaptor is used and securely fitted. If using a rubber seal adaptor, ensure the seal is correctly seated. If using a solvent weld adaptor, ensure surfaces are clean and appropriate solvent cement has been applied correctly and allowed to cure.

Check the integrity of the ring seal on the socket connection and the spigot joint. Ensure the boss pipe itself is not cracked. All connections must be watertight.

Ensure the 54mm hole saw is sharp and suitable for cutting plastic. Apply steady pressure and consider using a cutting fluid if necessary. Wear appropriate safety gear.
