Added bottle to ladder rad due to fall off of 0.5 bar every 2-3 days. Problem solved.
Great product weeping solder leek on elbow joint partly drained the system opened bleed valve at top of radiator threw this stuff in topped up system and like magic boom no leek looks like thick plastic but who cares no leek winner winner
Great did exactly what it says sealed radiator connection.
Easy to add to system, either via a drained radiator or expansion tank, hopefully will seal that tiny leak under floor, time will tell
Split the £100 into £10 wins so more people can benefit from doing reviews
Great service / product at the right price, put in the system yesterday, having drained and removed a couple of radiators to decorate.
this used with the Flexible Funnel helped to stop the leak I had.
Corgi Leak sealant. Poor product, looked like PVA glue
This has worked for me a few times now on systems with a small pressure drop over a few days. I use as a last resort, when customer does not want to investigate the cause of a leak but from their feedback, it has stopped the problem so can't fault it.
Not been able to find the leak quite yet, perhaps try again.
This is great stuff their was a small slow leak somewhere in the system that we couldn’t find so this was the last thing I could think of trying I drained down some water put this leak sealer in and ran the heating for one hour . I can now report the leak has stopped. It want at my house it was a friend so they were so happy that it was fixed and he didn’t have to pay for another fitter to come out and take money for nothing this year .
Quick and easy to use .done the job within a couple of hours
Sorted out my drops in pressure straight away would definitely recommend
Very thick and not as easy to put in as a previous one (different brand) but did the job and the price was excellent. Easy shopping with Toolstation.
Did what it said, small leak in an inaccessible place was slowly dropping the Heating system pressure. worked within 2 hours.
Bought this in the hope it would seal a small leak somewhere under the floorboards and it worked
