The Thomas Dudley Slotted Basin Waste (PSWWAS368154) is an essential plumbing component designed for homeowners and professional plumbers seeking a reliable drainage solution for bathroom basins with an overflow. Its primary benefit lies in its robust, corrosion-resistant plastic construction which ensures a secure, leak-free seal for standard 1 1/4-inch sink outlets. Please note that this model is specifically engineered for basins featuring an overflow, and it is not suitable for non-overflow sinks as the slotted design would lead to water leakage.

No, this is a 'slotted' waste. If you install this on a sink without an overflow, water will leak out through the slots.
The thread is a standard 1 1/4-inch BSP size, which is the industry standard for bathroom basins in the UK.
Typically, you can tighten the backnut by hand, though a basin wrench or large pliers may be useful for ensuring a firm final tighten.
No, this specific model is manufactured from high-quality, durable plastic.
No, kitchen sinks generally require a 1 1/2-inch waste; this product is designed specifically for bathroom basins.
Ensure the washer is seated correctly and that the backnut is tightened sufficiently. If the leak persists, re-apply a fresh bead of silicone sealant or plumber's putty.
Verify that the waste unit is correctly aligned so the slots in the waste are facing the overflow hole in the ceramic basin.
To install the waste, first ensure the basin drain hole is clean and free from old sealant. Place the top flange of the waste into the basin hole with a bead of plumber's putty or the provided washer on the underside to create a watertight seal. Secure the backnut from underneath the basin, tightening it firmly by hand or with a basin wrench; avoid over-tightening as this may crack the plastic components.
Regarding compatibility, this is a 1 1/4-inch waste; verify your existing pipework matches this standard. For care, avoid using harsh abrasive cleaners or concentrated chemical drain unblockers directly on the plastic, as these can weaken the material over time. Regular rinsing with warm soapy water is sufficient to keep the internal flow path clear.
