"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."
"All I can say is that this is a brilliant item to help with changing from the old imperial measurements to the new. It made a great accompaniment for the new radiator I purchased and made fitting so much easier and hassle free. Many thanks for such a brilliant and stress free item....."
"Overall this is a great product if you need to fit a new valve to an existing radiator and need to adjust the distance between the valve and the rad in one easy operation because they are a different size. (Saves having to move the pipes) or if you are fitting a new rad that’s a little bit smaller than the last. Each gives you around 50mm so that's a 100mm if you fit one either end. My only long term concern is that there must be a rubber seal between the pipe and the nut that connects it to the rad, so what’s the life span of this? Therefore how can you rate RELIABILITY? They have only been fitted for a month! But have used similar products before and keep a set in stock in case I need one at short notice. PERFORMANCE? FEATURES? It’s a bit of chrome pipe with a couple of nuts! Not a racing car! It works and does the job."
"Product looks great and seems like a good idea but despite careful installation and good allignment both internal joints leaked (the joint that slides). Its not clear how they work and there were no instructions so I do not know if I did anything wrong."
