Rated 5 out of 5 by from It’s simply very best No more complications to replace old to new as we had an odd size radiators and to get the same was impossible,and to use soldering technology was a no no. So we came across these telescopic extension valves and the whole job was so easy and clean

Rated 5 out of 5 by from Does the job perfectly These have been great when we changed a few of the radiators in our house. The old radiators were all old sizes, so we had to purchase the nearest size available and these helped take up the difference.

Rated 5 out of 5 by from Get out of jail free Makes changing a radiator with different pipe lenghts a doddle - simply pull out the desired pipe length as required for a clean and professional finish

Rated 4 out of 5 by from Simple and easy solution Easy solution to replace an old imperial size radiator with a metric size radiator without removing timber flooring. This saved me from removing all the furniture and then taking up the tongue and groove floor covering to reposition the pipe work. Probably half a days job. This was very straightforward to fit. Looks OK too.

Rated 5 out of 5 by from Life saver! Being something of a reluctant DIY'er, - who always assumes that anything he attempts is going to go badly wrong - I was worried about how the sliding part could offer a watertight seal - I get paranoid enough over leaks when using a compression joint on the end of a fixed section of pipe. Having had a burst radiator, and only being able to replace it with a narrower one, the 'nightmare' alternative was ripping up carpet and floorboards, re-routing and soldering pipes, so I gave one of these a go. I used 3 or 4 winds of PTFE tape around the olive and smeared the threaded part with jointing compound and it just worked!

Rated 5 out of 5 by from Great time and work saver. This TRV telescopic extension is brilliant. I was changing two rads, but did not want to alter pipe work to fit. These are time and work savers. Turn off TVRs to isolate system, drain rad and fit these with ample adjustment. Superb.
