FAQs

What is the main difference between an untrapped and a trapped gully?

An untrapped gully, like this McAlpine model, allows direct drainage but can let room odors enter from the waste pipe. A trapped gully contains a water seal to prevent this.

Can this gully be used in a standard bathroom?

It is specifically designed for wet rooms or shower areas where direct floor drainage is required. For standard bathrooms, a trapped waste is usually preferred.

What size pipe does the vertical outlet connect to?

The vertical outlet is 2" (BS EN 1329-1:2000). The included reducer allows connection to 1½" pipework.

How do I clean the gully?

Simply lift off the cover plate and remove the grate. Clean these parts with mild soap and water. You can then access the waste trap below for cleaning.

What floor types is this gully suitable for?

It is designed for installation in both concrete and suspended timber floors.

Does it come with a cover plate?

Yes, it includes a clamp ring and a cover plate. Cover plates are available in White Plastic, Polished Stainless Steel, or Chrome Plated Brass.

Troubleshooting

Gully is not draining effectively.

Ensure the grate is clear of debris. Check the waste trap below for blockages. Verify that the connected pipework is clear.

Unpleasant odors are noticeable.

This is an untrapped gully. Ensure adequate room ventilation, such as an extractor fan, is in place. Check that the seal between the gully and the waste pipe is secure.

Cover plate does not fit securely.

Ensure the clamp ring is correctly positioned and tightened. Check for any obstructions on the gully or cover plate rim.
