McAlpine Wash Hand Basin Self Closing Valve WHB1

By McAlpine Product code: 10705 Pack size: Each

Product Details

Designed to allow full use of storage space below the basin within the cabinet or furniture.

The internal membrane opens under water pressure to allow discharge to flow freely and then closes to form a seal to prevent foul odour or sewer gas entering the building.
The valve allows air to be drawn into the discharge waste pipe when negative pressures occur and eliminates the need for secondary ventilation to the discharge pipework. This allows for greater flexibility in the plumbing design.

The valve can be easily cleaned without having to disassemble the discharge pipework. Simply remove the split pin at the front of the valve, take out the plug and membrane and clean in hot soapy water. Reassemble and relocate the split pin in the slot provided.

• Overall height 62mm.
• 1¼" BSP female inlet nut x 1¼" universal compression outlet

McAlpine Wash Hand Basin Self Closing Valve WHB1 is rated 4.6 out of 5 by 13.
Rated 5 out of 5 by from Ideal trap if there is just 100mm space Well engineered piece of kit. Fits exactly above the drawers in the unit underneath the sink where there was very limited space.

Rated 5 out of 5 by from Basin spacin' Flexible waste used on basin installation had holed by rubbing on drawer below so like for like replacement undesirable. The increased clearance provided by this product solved the problem. The air admitting feature can be noisy when emptying a full basin.

Rated 5 out of 5 by from Great for tight spaces The new sink unit had a design issue where even the smallest trap fouled the bottom drawer, this was a godsend as it fits perfectly.

Rated 5 out of 5 by from Great piece of kit! Got this after I’d tried all of the conventional basin traps for a wall hung vanity unit. Due to the unit having a very little space inside none of the normal traps would fit, even the other ‘space saving’ traps were either too tall or too long. Now there’s room to spare.

Rated 3 out of 5 by from Waste good but... Parcelforce delivered a day late and needed to finish up so bought something else from a different supplier. Puts me off using Toolstation, which is a shame.
