Rated 5 out of 5 by from Does the job! Although not the cheapest fitting out there, this is a perfect match for the standard Drayton LSV to allow a single rad or a whole system to be drained. The chrome finish is far better than a lot of other drain valves. Make sure when you are running new pipework to rads that you allow for the extra length needed to fit these in.

Rated 5 out of 5 by from Easy drain valve Well worth fitting these to all radiators, especially the ones downstairs. Help you drain just the radiator if you’ve got it locked in or the whole system. Easier to remove a radiator for decorating, adding system chemicals( drain down to allow the corrosion inhibiter to be added) or the change out for a new one. This saves floor covering getting stained or damaged and lots of swearing by trying to lift a full radiator.

Rated 4 out of 5 by from Just the job - when it arrived Bought this when replacing some old imperial radiators with their metric alternatives and needed to fill a small gap between the new radiator and the existing isolation valve. It also restored the facility to drain just the radiator down simply for decorating purposes. Just one thing to aware of - these aren't carried on stock at a lot of sites and have to be delivered in. Currently, due to a glitch in the Screwfix system, this is not the next day delivery to store that was advertised on the stock checking section. Delivery was 3 days to store.

Rated 5 out of 5 by from Very useful indeed I'm changing each rad in my house & putting these on wherever I go. Granted, I've got the floor up and am resiting pipework and the rads but these make future maintenance and decorating so much easier and quicker. One room I fitted a nice Stelrad 1400x450 rad that sat perfectly central under the window - sods law the drop down for the pipework was bang on a double thickness joist one side, so rather than pull a dog leg with benders, one of these gave it just enough distance to rise up past it. Marvellous.

Can this be added to an existing 15mm TRV

Can i fit this in between the copper piping and an existing 15mm Thermostatic Radiator Valve? Will this fit a 15mm Drain?
Asked by: PeteGore
No this will not fit between the copper pipe and valve.

Replacing old radiators

I am replacing pressed steel radiators with a width of 1035mm (1.35m). Can I replace with a 1000mm and will this make up the difference?
Asked by: Tryeverything
Yes the drain off tail piece will make up the 35mm you need.

Which key fits the dotp

Hi. Do you supply the key to fit the drain off since the standard radiator bleed valve key is a larger square and will not open the valve?
Asked by: Goat2
No, you would need to use a adjustable spanner or adjustable grips.
