Leaking Drayton Lockshield Valve

[Harry_W]

Hi all, hoping you can help? I've fitted a Drayton Lockshield Valve to a new radiator pipe prior to installing a new radiator which hasn't arrived yet. However the valve is leaking slightly from the opening, not the nut and olive. How do I turn it completely off? I've tried tightening the cross head screw on the top but still leaking.

Sounds like the gland leaking using my X ray vision I think if you remove the centre screw the plastic cap will lift off and you can tighten the brass nut surrounding the spindle.

If you mean water is dripping from the valves outlet port ,then remove the plastic cover by taking the screw out ,below is a square end on the spindle, turn clockwise a bit to fully close the valve. Or you can just fit a blanking cap
On the outlet port.

Thank you Terry... Its the first time I've used a Drayton TRV so not come across the cap being secured in place by a screw.

Did you mean a Drayton Thermostatic Radiator Valve (TRV)?

If so, there is no 'off' position on the valve, so it will always leak slightly. If you have the plastic 'decorators cap', which comes with a new TRV, you can remove the head (undo knurled nut under the head), fit the cap and screw down. A bodge is to insert a small coin, or something similar, into the head, replace head and tighten carefully until the water stops.

Correct but please explain to people that removing the head will result in a flood , op , drain first then remove valve head else your getting wet.

Mea culpa. I had forgotten that the TRV was not connected to the radiator.

You could always fit an end stop on the open connector; it would save draining down.
