The first thing to do when you have a leaking central heating system is to determine where the leak is and is coming from and to then decide if you require an emergency plumber in London or anywhere else in the UK. The other option is, is there anyway you can solve the issue yourself.

In most cases it may be a tightening up of a fitting or a simple fix but in some cases it may also leave you scratching your head wondering on what to do.

A water leak may start from a knock or from corrosion due to a mix of damp air, water and contact with a metal. It has been found that the plumbing under concrete has a high chance of corroding and never being found. The only way to tackle this may be just to completely replace the lot.

As long as the leak on the copper pipe is within the central heating system and not of a large rate of water pouring out, there is the solution to using a chemicals when it comes to your leaking central heating system. It is very important that the leak sealer does not come in to any contact with the cold water drinking supply, as this may be highly dangerous. If you have any concerns, it may also be good idea to contact the manufacturer or their help line to find out what you can and can’t use it for.

The central heating chemical also comes in a tube which also makes life easier to use if your putting it into a pressurized central heating system. If your using the tub version then the easiest way is to just put it into the central heating storage tank but also making sure that you have drained down some water and your filling the central heating also. This will make sure that the chemical then enters the central heating system and start to work at the area of where the water is leaking.

A 500ml dose of MC4 will cover at least up to 10 radiators but if you have more radiators that the 10 you already have then you must use more of the leak sealing chemical.

All leak sealing agents are made slightly different and will set in different time scales. There is no time that can be put on how quickly the leak will seal due to the size of leak and the volume of water in the central heating system. Please note it may not work on all types of leaks as is only a solution for slow leaks. A good way to find if you have a leaking central heating system is to acknowledge the water pressure keeps going down on the central heating system after so long.

If you are an emergency plumber in london or anywhere else in the UK, you may find the above leaking sealing chemical to be of some good use but if your a customer/occupant of the home where the leak is and your looking for an emergency plumber to fix the leak without the hassle of trying to solve this yourself, then please give us a call on the below contact number.
