Rated 5 out of 5 by from Works great (as long as you use 2) I've had a slow leak in the central heating system for a few years now. The heating engineer said to use two bottles of sealer as we have a number of radiators in a large house. So I used these to top up the two radiators that seemed to lose most of the water. I topped up the system a little, not too much as this won't form a seal from the leak. After leaving a day or two, I topped up again and now it's been steady pressure for a month. Can't recommend this enough.
