If there is one thing that can be guaranteed in life, it is that a problem will always rear its ugly head when funds are tight. Whether that is a puncture in your tyre, a sick pet, or a leak in your central heating system, there is never a good time for one of these problems to arise.
When these types of situations arise, the temptation is to find a quick and inexpensive fix, to get you through the problem temporarily, and allow you time to save up the necessary funds to do the job correctly. When it comes to leaks in your central heating, leak sealer would appear to be and is often marketing as being that perfect solution. Unfortunately, as with most quick fixes, the reality is much different from what the manufacturers would have you believe.
How Does Leak Sealant Work?
Apart from the financial benefits of leak sealant, with the average bottle costing sound £20 versus the average call-out cost of a plumber at £100 before he or she even does anything, there is very little technical knowledge or expertise required to use leak sealant, Depending on the location of the leak, and your equipment, all that is required is for the user to pour the product into their system, and then simply wait for the magic to occur. Think of Leak Sealant as a type of glue added to a sniffer dog. When you pour the leak sealant into your central heating system, the sniffer dog hunts around your system, searching for the source of the leak. When it finds that leak and begins to drip out, it is exposed to the air, which solidifies the product sealing the hole- problem solved!
That Sounds Perfect – So What’s The Problem?
Although the theory sounds very promising, the reality is very different. When you use leak sealer, you are essentially applying a temporary fix, the equivalent of putting a plaster on your child’s knee when they fall over and cut themselves. Eventually, at an undetermined time, that plaster is going to fall off, and the cut will still be there. That is precisely the same scenario that many homeowners find themselves in when using leak sealant.
What About Radiator Leak Sealant?
The critical factor behind the theory of leak sealant is to do with its activation once it is exposed to air. There should be no air in your central heating system in an ideal world, but once again, the reality is far different. Anyone who has ever had to bleed a radiator knows that there is and always will be air in a central heating system. This air and the air in the air valves in the boiler activate the sealant, leading to further problems, leaks, and other issues, which can be significantly more expensive to repair in the long term. The most common issue is that where there is a leak in the system caused by the leak sealant, that the rust inhibitor becomes diluted, which, as the name suggests, leads to rust forming. Oxidisation then happens, which in turn produces a gas that generates a chemical reaction with the sealant. Small amounts of debris settle in the radiators due to this reaction, which then makes them partially block, leading to inefficiency and other problems. Do you think you have a leaking radiator?
What Is The Worst-Case Scenario?
Hopefully, the explanations above will have made you recognise and understand the false economy of using a leak sealant in your central heating system. However, if you are still tempted, let’s look at another potential problem with these types of products. What happens if the size of the leak is too big for the amount of leak sealant? Now the owner is faced with the issue that their central heating system is still leaking but additionally is now filled up with sealant, which exacerbates the problem. In this situation, the only solution is to have the entire system flushed, which, interestingly enough, costs as much if not more than fixing the leak properly would have cost in the first place. And then, the leak still needs to be fixed, in effect doubling the cost of the entire process.
If Leak Sealants Are Such A Poor Product, Why Are They Still Available To Purchase?
In our opinion, using a leak sealant product is a recipe for disaster and one that we personally would never recommend. We have, after all, seen the damage caused by these products. However, there may be some advantages to using these types of products in certain very limited situations. If you have a very minor leak, which can be topped up every month or so rather than every few hours or days, then a leak sealant product applied close to the source of the leak might be a reasonable solution. However, in our opinion, even this is flirting with potential disaster, it might work for a short period of time, but eventually, the problem will need to be fixed properly. Leak sealants are at best a quick and temporary fix, and financially nothing other than a false economy.
