Product Information

Full details

The OsmaDrain 110mm Double Socket Adaptor is an essential component for drainage professionals and DIYers working on gravity-fed foul and surface water systems. It provides a reliable, secure connection between modern plastic drainage pipes and legacy thinwall clay spigot systems, specifically the SuperSleve range. While it offers excellent durability and ease of installation, users should verify their existing pipe material to ensure it is compatible with the BS EN 295 thinwall specification before purchasing.

Extended Product Information

FAQs

Can this be used on thick-walled clay pipes?

No, this adaptor is specifically engineered for BS EN 295 thinwall clay spigots and will not fit traditional thick-walled clay drainage pipes.

Does this adaptor require solvent welding?

No, it utilizes a push-fit ring-seal mechanism, meaning no solvents or glues are required.

What is the maximum depth for this fitting?

The OsmaDrain range is rated for use in gravity drainage applications at depths of up to 10 meters.

Is this suitable for foul water systems?

Yes, it is designed for both foul and surface water gravity drainage systems.

What size pipe does this fit?

This is a 110mm nominal diameter adaptor designed to connect to 110mm plastic pipe and standard thinwall clay spigots.

Troubleshooting

Joint is difficult to push onto the pipe

Ensure the pipe end is properly chamfered and use an adequate amount of silicone-based jointing lubricant.

Visible water leakage at the joint

Check that the ring seal is seated correctly in its groove and that the clay pipe spigot is free from cracks or deep scratches.

Pros and Cons

Pros

Tool-free push-fit installation saves significant time
Reliable ring-seal design minimizes risk of leaks
Ideal for retrofitting modern plastic pipe to older clay systems
Suitable for deep drainage applications up to 10 meters

Cons

Not compatible with thick-walled traditional clay pipes
Requires proper pipe end preparation to ensure a watertight seal
Limited to specific BS EN 295 standard clay dimensions

Setup, Compatibility & Care

To ensure a successful installation, follow these steps: First, clean the end of the existing clay pipe to remove dirt, debris, or sharp edges that could tear the seal. Ensure the pipe is cut square. Apply a thin layer of manufacturer-approved pipe lubricant to both the spigot and the internal seal of the adaptor. Push the adaptor onto the clay pipe until it hits the central stop. Care should be taken not to force the pipe against the stop during extreme cold, as some clearance allows for thermal expansion. Periodically check drainage inspection chambers to ensure no debris has gathered at the junction point.
