Howdens Lamona Professional Mono Tap9158 Valve

If your Howdens Lamona Professional Mono Mixer Tap9158 Valve Valve is dripping continuously then you might need to change your Valves.

If it is only dripping intermittently then it is possible that debris is stuck behind the Aerator at the tip of the spout.

If your Tap is dripping where the Spout meets the Base you might need to replace your O Ring Kit.

Ideally you should remove your own valve before ordering a replacement valve to esnure that you order the correct one and that way you would also know if you require the brass bush or not.

Measurements:

• Nut Height: 8mm
• Splines: 28
• Overall Height: 53mm
• Diameter at thread: 21mm

Before ordering your replacement Tap9158 Valve, you might require the Bush for Valve as well. This is a brass cylindrical piece that the valve sits into inside the Tap. Sometimes these parts stick together and when the Valve is removed, the Bush comes out as well. Should you also require a Brass Bush (one per valve), the same part number SP3868 is used on both Hot and Cold Valve.

There are more detailed tips / advice here.  This Blog post My Kitchen Tap is dripping should explain the most common causes (and parts required) to fix a dripping Kitchen Tap.
• My Valve has a different coloured seal than the one you have sent me?  Due to modifications over the many years that this Tap has been in production, we supply the universal Lamona Valve that covers all these changes.  This is based on the manufacturer’s recommendations.
• My valve looks wider and completely different from the pictures here / the one I ordered ? Is the Bush stuck to your own Valve ? That is the round extra piece of Brass that surrounds the valve.
