Sentinel X400 Sludge Remover Have been having problems with some of my radiators not getting hot, put the liquid in and within minutes the problem was cured. Could not believe how quickly it worked. 17 Apr 2015
Brilliant! For the size of our ancient one pipe CH system, I had to buy two bottles...so a little pricey. But what a difference! The boiler is a lot quieter, the water is a lot hotter and several of the radiators that were only ever luke warm are now hot. We should have used it 10 years ago when we first moved in this property. 7 Apr 2015
Sentinel X400 Works I bought this because our domestic hot water supply had been reduced to a trickle and I reckoned that the pipes from the hot storage tank were full of sludge and limescale. Having run the bottle into the tank and allowed it to do its job for an hour, I was amazed at the difference it made when I flushed the system through. Sentinel X400 really works and we've never had the hot water running so well in our house. Thanks ScrewFix for selling such a thoroughly useful product! 4 Mar 2015
