What is causing your boiler to lose pressure?
Have you noticed a loss of pressure in your boiler? Check out our article if you're concerned about your boiler pressure dropping and what to do about it.
Make sure you hire a gas safe registered engineer like the one at SS Boiler Installation to protect your home and family. In this article, we will discuss the steps to hiring the right person:
Why is my boiler constantly losing pressure?
Make sure all radiator valves are not leaking. In many cases, the leak runs down the copper pipe, hiding it from view. Often, people think of leaks as large-scale leaks with water gushing from pipes. A large leak will naturally cause your boiler to lose pressure, however, the most common leak is a small one the size of a pinhole. Small leaks cause a gradual loss of pressure, leading to your boiler’s failure. If you suspect a leak, look for damp patches under radiators, pipework, or underneath your boiler.
Locate the high-pressure relief pipe. It’s usually outside and not somewhere you look all the time. If this pipe drips, you have a leaking pressure relief valve. Getting a plumber in at this point is the only option.
Air is sometimes created by the system. An air vent is usually used to expel this from most pressurised systems. As a result, the pressure is reduced. It is caused by a lack of heating system treatment inhibitor in the water.
It is possible to set the pump speed too high at times. Water that doesn’t escape the pump fast enough can cause cavitation. As a result, the water particles are split. Due to the fact that water contains oxygen, cavitation releases this oxygen. Air vents release oxygen, resulting in a drop in pressure. You can avoid this by lowering your pump speed and ensuring your heating system is not blocked.
Problems with safety devices or faulty parts are the most common causes of gas boiler pressure loss.

Start by checking your boiler’s display panel for error codes. You can look them up online or in your boiler’s manual. It is also a good idea to check if the pilot light on your boiler has gone out. The pilot flame will be out if your boiler has stopped working. A professional can help if you are still unsure what the problem is.

It might also be other internal problems inside your boiler that are causing the problem, especially in winter when your boiler expands and contracts. Call a heating engineer to diagnose and fix a problem with your boiler pressure if it keeps dropping. It might be time to replace your old boiler if it consistently loses pressure.
