The PBSL Group 110mm 87.5 Degree Double Socket Drainage Bend is designed for professional contractors and serious DIY enthusiasts working on underground sewage or surface water systems. Its primary benefit is the push-fit connection mechanism that significantly reduces installation time compared to solvent-weld alternatives. However, users should note that the system requires proper lubrication and accurate alignment to ensure the captive rubber seals remain seated correctly during assembly.

No, these are designed as push-fit connections. Using glue can actually damage the rubber seals and interfere with the fitting's intended flexibility.
The 87.5-degree angle is designed to provide a slight fall, which is necessary to maintain effective water flow through underground drainage systems.
While it shares similar sizing, this is specifically designated for underground drainage use. Check local building codes for above-ground piping requirements.
While installation is physically possible without it, we highly recommend it to maintain the integrity of the seal and make installation easier.
The fitting is made from high-grade PVC suitable for underground drainage and sewerage systems.
Ensure the pipe end is properly chamfered and apply a generous amount of silicon lubricant to both the pipe and the seal.
Remove the pipe, inspect the captive seal for debris or displacement, clean the area, re-lubricate, and ensure the pipe is inserted to the full depth.
For a secure and lasting installation, always deburr the ends of the PVC pipe before insertion to avoid damaging the internal seal. The use of a high-quality silicon-based lubricant is strongly recommended on both the pipe end and the rubber seal; this reduces friction and allows the pipe to slide into the correct depth without excessive force. Regularly inspect the surrounding soil area for signs of settling or movement, as shifts in ground level can stress underground joints. This fitting is compatible with standard 110mm drainage piping; always confirm your pipe wall thickness meets the specification for push-fit components to ensure a vacuum-tight fit.
