Put in to the system worked for the first day by holding pressure on the second day of using the central heating pressure dropped off again and never regained so I cannot really recommend this product

Tried this after a very honest boiler repair man advised us to try it as our boiler was losing pressure slowly over a week or so. Added the sealer to the system via a towel rail radiator as per instructions, and our boiler has since held pressure firmly over the last 2 weeks. Well worth a try if you’re having similar issues, very impressed with the product!

Great product. Does what it says. My boiler was losing pressure and now, after more than 2' months, everything looks good. If you have a bigger system is better to use 2 bottles, like I did.

Well it took a couple of days to work - however - its working now and has saved a lot of hassle and money as well, would recommend without any doubt.
