"Unlike some other reviews this worked a treat and hasn't leaked although only been 24hrs since installed but as it's on a pressurised combi system run at full heat and hasn't leaked yet all looks good. Used to replace existing imperial rad with shorter metric rad, note that this will not connect to a TRV, only the lockshield valve (Product Code: 33920). I used this union version on the lockshield valve side and the compression version (Product Code: 10954) on the TRV side."
"Bought this to allow me to fit new metric sized radiator in place off imperial sized one.Seemed like a good idea to save having to alter pipework Found that the valve tail fitted into the radiator OK but the connection on the valve tail (22mm) was too large for the Danfoss TRV (15mm)fitted to the pipework Perhaps this should be noted in the product description"
"Basically there is one fatal flaw in this product: it leaks. It leaks where the screws slide along the pipe. All of them leak. Out of four I bought every single one leaks. Some leak on both sides even!
So, why give it 5 stars? Because for some reason the reviews are coming up "Highest rated first" instead of the normal "Newest first". So I've given it 5 stars in the hope someone will read this instead of buying this product accidentally like I did.
Obviously this was once a good product, but no longer. Go to the top and sort by "Newest first" and you will see all the results are bad until mid 2012 after which all the reviews are good.
"Great solution when fitting radiator of a slightly different size. I had to replace a radiator with a length of 750mm with a smaller 700mm one and this extending tail valve saved having to resite the pipework."
"I was replacing old radiators which were slightly wider than the ones I was replacing. These make this easy without having to alter pipe work I actually bought the wrong ones, I had to swap them for the Compression Valve Tail (these not fit std radiator vales) But the idea is the same. great product"
"I am a competent DIYer and was cahanging an imperial radiator for a metric one - the pipes are in a concrete floor. The telscopic tail easily filled an awkward gap. To date it has not leaked - time will show how reliable it is. The description and part code on line do not agree with the catalogue."
"this product is good if you need to replace old imperial rads with metric ones and do not want to repipe,the one thing you must do is find the centre line of the old valves and mark it on wall then do the maths with the rads from that mark so you get the new rads to be in line with the old valves this should let these telescopic extensions work well."
