Extended Product Information

FAQs

Is this washer compatible with all bathroom basins?

It is compatible with all basins that utilize a standard 1.1/4 inch waste outlet.

Do I need plumbers putty when using this washer?

While the washer is designed to create a seal, a small amount of sanitary sealant or plumbers putty can be used if the basin surface is uneven.

What tools do I need for installation?

No specialized tools are strictly required, though a basin wrench may help tighten the nut beneath the basin.

Can I use this for a kitchen sink?

No, kitchen sinks typically require a larger diameter waste (usually 1.1/2 inch), meaning this washer will not fit.

How often should I replace this washer?

There is no set replacement schedule, but you should inspect it whenever you perform maintenance on your taps or waste pipe.

Troubleshooting

Water still leaking after installation

Check that the washer is centered correctly and verify that the locking nut underneath the basin is fully tightened.

Washer appears loose

Ensure the basin surface is flat and the waste flange is not obstructed by old silicone or debris.

Washer does not fit

Confirm that your waste outlet size is indeed 1.1/4 inches; if it is 1.1/2 inches, this specific washer is not the correct size.

Pros and Cons

Pros

Ensures a reliable, leak-free basin connection
Easy to install without professional plumbing tools
Durable material composition for long-term use
Fits standard 1.1/4 inch waste pipe configurations

Cons

Not suitable for larger waste outlet sizes (e.g., 1.1/2 inch)
Requires manual alignment for a perfect seal
Not intended for industrial or high-pressure commercial plumbing

Setup, Compatibility & Care

Installation is straightforward. First, remove the old waste fitting and clean the area thoroughly. Slide the Thomas Dudley washer onto the waste outlet, ensuring it sits flush against the flange. Insert the waste into the basin hole and tighten the locking nut from beneath the basin.

Compatibility: This washer is strictly designed for 1.1/4 inch basin wastes. It is not compatible with shower traps or kitchen sink wastes, which typically feature larger diameters.

Care: Avoid using harsh chemical drain cleaners, as they can degrade the integrity of rubber or synthetic seals over time. Periodically check beneath the basin for signs of dampness to ensure the connection remains secure.
