Leaking joints
25 Feb 2014
By Alwaysworking
, Coventry
"Bought this as I had some leaking joints and really didn't want to undo and drain the system. A bit fiddly and not too clear on how to use, removing the bleed valve and filling that way is messy as you pressurise the rad and when removing the pipe from the can it squirts out until you get the bleed valve back in, messy but is do-able. Fitted bleed valve within ten minutes drips had stop, easy and cheap."

Simple

"I found this easier to use than leak sealers that use a cartridge and gun but it still suffers from the same problem in that when you disconnect you always get some of the gunk blow back out of the vent. Very messy and hard to clear up. It took 2 days after use to seal the system and there has been no problem since."
