No Nonsense Inhibitor Although I have no gripe with the product or performance, I did learn one important fact & that is when you think you have emptied the cartridge keep it facing down as some fluid by-passes the sealing ring and spills all over the bathroom floor when you least expect it....................lovely, was I popular or what?? 15 Sep 2014
Ruined my new boiler I recently had a new boiler in Feb. I have just completed a bathroom remodel and replaced my old radiator with towel rail from Screwfix. I used this product as the guidlines said that I needed to put this in the central heating system to avoid corrosion. Within 20 minutes of using this product the Cold water inlet and system return on the boiler has started leaking and the boiler has an error code! I am usure of the damage at this stage but get confirmation from your gas safe engineer prior to using. I have just learnt a very expensive lesson! 6 Jul 2014
Good Product This was easy to use and being a small quantity quick to input to system.I believe someone had problem in input but u must de-pressurise system by turning off water feed and killing pressure in system by emptying water from the lower Drain cock this will allow u to take out a radiator vent screw (Preferably on top floor)with no push-back of radiator water,do not drain out a lot,probably no more than 1ltr then turn back to stop.After injection into rad. put screw back into rad. and water feed ON. Job done,start up,when u have checked u have no leaks from the bits u have adjusted u can stop system and vent air that u might have in rad. Best of Luck 31 Oct 2013
complete mess wont be buying this again! the bottom of the inhibitor just fell out as i was taking it up stairs resulting in a big mess. the instruction say that once connected to the rad turn one rad valve and push the contents into the radiator, however as soon as you open one valve the pressure from the water stops you being able to injected anything. 5 Aug 2013
