no nonsense leak sealer great value but must buy filling kit with this it makes the job so easy. 12 Feb 2015
Solved my problem Thanks a lot I don't know how long it will last because this was asking a lot - my leak was actually in the heat exchanger! Anyway it has stopped and the boiler is working and if it can keep going until the weather warms up that will be great!!! I can then change the boiler without suffering from the cold. 10 Feb 2015
good quick fix good for inacessable leaks before moving into current house central heating had been fitted and living room radiator had pipes leading under the floor no leaks anywhere else but looses pressure sure minor leak under the floor. bought this item over a year ago as a hopful fix and was shocked how well it worked it lasted for 12-18 months now problem has reemerged retreated and results seem good, cant hope for a long term cure but in the short term got me out of trouble with minimal work 27 Jan 2015
No nonsense leak sealer Very good, the seepage from my oil fired central heating boiler stopped overnight. However, it is not stressed that the best way to administer the liquid is via one of the radiators. If you dose the head tank it may take a while before it takes effect. I used a 60ml syringe and a 75 mm length of 2mm plastic tube to feed it in through the radiator bleed valve. This could be added as part of the order. 4 Dec 2014
