"I have used these kits before, always worked and this one did too. Great for freezing pipes so you don't have to drain down. I wanted to remove a radiator permanently and cap off the pipes (8mm). I wrapped the jacket around both pipes at once and they both froze. There wasn't much pipe to play with as they came out of the concrete floor and into the radiator, but I froze the pipes and cut through the frozen area and the ice plugs held while I capped off the pipes. A success."
"I used this to install isolator valves in my house for both kitchen and bathroom. Totally reliable. Just rememberto get everything ready , pipes cut/joints ready, wrenches etcc BEFORE you freeze the pipe. Do the cold one first so you get the idea as freezing the HOT pipe will be quicker to do, as the heat does melt the frozen plug much quicker than the cold."
"Saved me an absolute fortune. I needed to fit a new stopcock as the old one had corroded and was unusable. Fitted the jacket to a vertical 15mm pipe, followed the instructions and taped the bottom of the sleeve. Worked a treat with not a drop of leakage. Can't recommend highly enough."
"This is a remarkable item. I needed to change a radiator which was starting to leak and draining, refilling and bleeding the whole system would have taken the best part of a day. I'd never used a pipe freezer before and so I approached it for the first time with some trepidation. But it was so easy to use and pretty well mess-free.
If you read the instructions carefully and follow them exactly then you should have no problem at all. I had to work on two low-pressure vertical 15mm copper pipes and so needed 2 kits - this was expensive but the freezing was done quickly (about 10 minutes total each one) and gave me ample time to fit the new valves.
You need to fit the jacket snugly around the pipe and the temperature inside it gets very low indeed so be careful not to touch the frozen part of the pipe with bare fingers."
"I was very dubious about this but have used it twice, successfully both times. First time was on a 22mm vertical copper pipe. I used the whole tin and worked well. Second time was on 15mm plastic pipe to a rad. As someone suggested I cut the sleeve in half and used 1/2 tin on each joint again no problems. It does seem very expensive but when you consider the agro in draining down and then possible air locks filling up again it is well worth it. I would certainly recommend it, but still think it could be cheaper."
"simple to use as long as you have got good access to the pipework. Only used it for compession joints dont know how good it would be for soldering jobs. Although it worked well it can work out a bit expensive as you need to use at least a whole can for each joint"
"I read reviews on this and other sites about people using half a can a time - I bought two cans just in case!! Half a can did me on 15mm copper pipes - the central heating water was about 5 degrees at the time. No leakage at all. Brilliant product, keep one handy !"
"Used it to remove rads...didn't want to drain the system, etc. Was a little sceptical and there seems to be some guess work as to when the ice plug forms...on my job I found it easier to hold the collar behind the pipe and apply the freezant directly (wearing a golove of course), didn't seem to work so well applying through the collar.
But...great product, worked a treat. Will definitely use agin."
"To say I was sceptical of the whole pipe freezing thing was an understatement! I had 2 15mm pipes to freeze as I needed to cap them both off, one mains fed and the other from the communal boiler system (feeding over 18 flats). It would have cost me thousands to have the system drained down not to mention the inconvenience of not hot water to 18 flats! Instead I opted for the £20 option which was to freeze both pipes and cap them myself! And it worked! No drips, both pipes froze, even the hot and I managed to cap them both within 20mins! I would recommend this to anyone that needs to access water pipes that cannot be drained down or isolated."
"Brilliant product. Does what it says on the tin, saved me having to drain heating system down when changing a radiator and valves. As a previous reviewer said a twin pack would be better value as you need 2 cans per radiator."
"The sleeve works for 8mm-28mm but the can is only sufficient for upto 15mm pipe. Also, horizontal pipes are much preferred.
Having said that, I used this kit to replace a broken 22mm gate valve mounted vertically!!! The water in the pipe was cold already and the ice plug only held for about 10 minutes - but I only needed 2 minutes as I had already loosened the compression joint and the replacement was to hand."
"I changed my kitchen sink and old taps for new monobloc type. I needed to isolate the hot water supply, as it had no valve, this kit allowed me to freeze the pipe and install an isolation valve. It was sooo easy. The new sink is in and looking good. This product must rate as one of the best I have used."
