Didn't work for me.
Bought this on the strength of the advertising. Tried it in my CH system to cure a small leak. It did not work, then on the tin I read it could take up to 6 bottles to cure a leak. Never saw this on the advertising. At £18.+ a bottle, cheaper and more effective to have to the leaking joint replaced. Wasted my money.

Excellent cure
Had a leak in my central heating system, causing loss of pressure. With all solid floors, we couldn't find the problem. Put a couple of cans of CT 1 in the system (21 radiators!) and it seems to have solved the problem.
