How to Repair a Pinhole Leak in a Central Heating Radiator

Do you need to repair a pinhole leak in your central heating radiator?

Fixing small cracks and leaks can be tricky, especially if you’re new to such repairs or using an insufficient sealant. Pinhole leaks in a central heating radiator can be difficult to locate, which is probably going to be the first step in repairing the leak. Once you’ve identified where the leak is coming from, you can go about repairing the pinhole leak in your central heating radiator.

This is where Miracle Seal comes into play. Miracle Seal provides a permanent solution to small leaks in domestic, commercial, and industrial radiators and heating systems. What makes Miracle Seal so useful for repairing pinhole leaks is the fact that it’s incredibly versatile, dependable, and easy to use.

If you have a pinhole leak in a central heating radiator, here’s how you can fix it:


1. Find the source of the leak

As we mentioned above, the first step to repair a leaky radiator is to locate the source of the leak. This is difficult to do when the radiator is wet. So, grab a towel, dry the surface of the radiator and check if you can see where the water is coming from. There are a few main places where the leak will originate and this includes the main body of the radiator (and panels), the valve, pipes, or the radiator valve nuts.


2. Use Miracle Seal to seal the leak

Once you’ve found the source of the leak, you’re ready to use Miracle Seal to repair the leak. Pinhole leaks tend to be very small. However, just because it seems like a small leak, it can still cause a lot of damage if it isn’t dealt with as soon as possible. Replacing the radiator is usually an unnecessary and expensive task that can be avoided!

Water damage can impact the surrounding area of the radiator including floorboards, carpets, and in worst-case scenarios, cause damage to the ceiling (if the leak is coming from a second floor). Instead of rushing out to replace the existing radiator with a new model, you can save a lot of time and money by using Miracle Seal to repair the leak.

Miracle Seal is great for sealing thin cracks and pinhole leaks. It is a water-based suspension of non-clogging particles and contains lubrication and anti-corrosion additives. Miracle Seal can repair small cracks without clogging the system. In emergencies, you can rely on Miracle Seal to fix a leaky radiator with no fuss. The soft particles of the sealant will not clog the radiator, which can be a common issue with typical sealants. However, Miracle Seal does not clog and can be used in all types of radiators.
