FAQs

What type of pipe does this elbow work with?

This elbow is specifically designed for 25mm MDPE (Medium Density Polyethylene) pipe.

Can this fitting be used for hot water lines?

No, this fitting is approved and designed for cold water systems only.

Is installation difficult?

No, installation is straightforward using a compression mechanism that requires basic tools like a wrench. Ensure the pipe is clean and properly inserted.

What does WRAS approved mean?

WRAS (Water Regulations Advisory Scheme) approval means the product has been rigorously tested and meets the high standards set for products that come into contact with drinking water in the UK.

How many fittings are in a pack?

Each pack contains 15 John Guest MDPE Compression Elbows.

Can I use this for underground installations?

Yes, this fitting is suitable for both below-ground and above-ground cold water applications.

What if I notice a small drip from the connection?

Check that the pipe is fully inserted and the compression nut is tightened to the recommended torque. Ensure the pipe end is clean and undamaged. If the problem persists, consider replacing the fitting or pipe section.

Troubleshooting

Leak at the connection

Ensure the pipe is fully inserted into the fitting and that the compression nut is tightened sufficiently. Check the pipe end for damage or dirt; re-cut if necessary and re-install. Verify the correct pipe size is being used.

Difficulty inserting pipe

Confirm the pipe is the correct 25mm MDPE. Ensure the pipe end is clean, free of burrs, and slightly chamfered if needed. Warming the pipe end slightly in warm water can sometimes help with insertion.

Fitting does not hold position

This is rare with compression fittings. Ensure the pipe is fully seated and the nut is adequately tightened. If the issue persists, the pipe may be deformed, or the fitting may be damaged.

Setup, Compatibility & Care

Setup:

  1. Ensure the end of the 25mm MDPE pipe is cut square and clean. Remove any burrs or dirt from the pipe end and the interior of the fitting.
  2. Loosen the compression nut on the elbow.
  3. Push the MDPE pipe firmly into the elbow until it is fully seated against the internal stop.
  4. Tighten the compression nut by hand, then use a wrench to tighten it an additional 1/2 to 3/4 turn. Do not overtighten.
