Rated 5 out of 5 by Sentinel Rapid The best system I have used in order to get the liquid into the central heating using a bleed valve. The simple bead in the tube prevented back flow from the bleed valve. Simple but ingenious and the cans empty beautifully without any spillage 11 Dec 2015
Rated 4 out of 5 by SENTINEL RAPID DOSE Recommended by my plumber as a quick and easy way to top up my Central Heating system. Collected from the Hawick store whose staff where friendly and very helpful. 11 Oct 2015
Rated 5 out of 5 by Amazingly simple and effective Having had to drain my pressurised central heating system to carry out a repair I came across the issue of needing to somehow introduce inhibitor into the system. There was no easy point in the heating system to introduce the inhibitor and having watched numerous youtube vids it looked like a hand pump was the only option. Then I came across Sentinel and went to the website and watched the video, it seemed to good to be true but I had nothing to lose (apart from the cost of the can). The nozzle and injector included with the can is absolute genius and works exactly as on the video, I was able to inject the inhibitor through the very small bleed screw hole, the magic bullet in the tube prevented any escape and the job was done in 5 minutes with very little mess. Absolutely brilliant! 12 Sep 2015
