Fernox Leak Sealer
Happy hols - 2 years ago
My central heating system sprung a leak from a pipe/Union sealed in a concrete floor one week before setting off on holiday. I added Fernox Leak Sealer via the header tank after emptying the tank and draining a bucket of water from the system - to ensure the sealer was drawn in to the system. I then ran the heating for a few hours to mix through system. Following morning all dry, no more leak!
The sealer has appearance and consistency of PVA glue so was too gluppy to add via a radiator. There is a version of this sealer for adding via radiator but it's much more expensive. This product did exactly what it promised to do and saved a huge amount of hassle.
