Why Leak Seal is not a ‘quick fix’…

If you have a boiler problem, you’re looking for a quick solution and as cheap as possible.

It does not come much cheaper than a bottle of leak sealant at about £20… Fernox F4 and Sentinel are very common brands, these come in a variety of applicators, from a bottle to pour into a header tank or magnet to applicators used in a radiator bleed valve and pressurized cans to inject at the fill point.

Think of leak seal like a plaster, it won’t last…

The idea is that this fluid will only cure in contact with air and that should be where the leak is. However these are for VERY minor leaks, the sort that you top up every few weeks and not within a couple of day or even hours, add the cost of a plumbers call-out and leak seal is about £100 and often either only slow the leak or the leak seal fails after a short time.

Leak Seal is often a false economy…

We talk to most boiler manufacturers and leak seal will often invalidate any warranty or at best is considered a poor solution to a problem. Like a plaster over a cut, it will fall of off at some point and in it’s now solid form can block your boiler causing either a big bill of over £500 and you still have the leak to find!

Leak seal can also cause problems with tracer leak detection, as it treats the trace gas as air and sets, often fixing the leak but only for a while. This is why systems treated with leak seal are covered under our ‘No Find – No Fee’, as it is looking for a moving target…

It is far better to locate the leak and deal with it permanently, this will initially cost more, but is often absorbed as part of an insurance claim, making it far more cost effective than the temporary solution of leak seal…

This is where UK Leak Detection offers a far better option…Locate the leak and permanently fix the problem.
