Does your boiler keep losing pressure? We know it’s incredibly inconvenient. There are numerous reasons why it’s happening. It may be due to a hidden leak, but there are also other variables to consider. It can affect your heating system and disrupt the boiler water pressure.

Here are 7 (seven) reasons that cause a boiler to lose pressure:

Radiators with Too Much Air in Them

Don’t let air bubbles develop in your radiators as it can stop heat from building up in your home. They stop the hot water from circulating efficiently, limiting the warm air produced by your central heating equipment. The bubbles develop due to various reasons, from your system being full of sludge to incorrectly topping up the boiler.

Leaking Solder Joints

If there’s a weeping solder joint, it’s a sign of a weakness in the pipework. This issue is common in older heating systems because the joint can become vulnerable over time. Even if the leaks are small, it can change the boiler water pressure that can damage your home.

Dripping Radiators, Towel Rails, and Valves

If you notice moisture or water on or around the radiator valves, then that means it’s leaking. It’s also one of the most common explanations for a drop in boiler pressure.

Faulty Pressure Relief Valve

A faulty pressure relief valve will prevent the boiler from shutting off correctly. Instead, it will release the pressure. This issue leads to erratic and uncontrolled water pressure, preventing the boiler from operating sufficiently. If you notice the water escaping from the pressure relief drain, it indicates that the relief valve is failing.

Holey Auto Air Vents

You’ll recognize leaking auto air vents if you see that they are weeping with moisture or water or stained with limescale or rust. The auto air vent’s role is to keep the central heating systems from retaining air so that a leak would reduce the boiler water pressure.

Defective Expansion Vessel/Tank

An expansion vessel or tank keeps the water heating systems from creating too much pressure. If it’s defective, it will be counterproductive and can even cause unnecessary boiler pressure.

Broken Pressure Gauge

The pressure gauge shows the live boiler pressure. Once it becomes broken, the reading will be inaccurate or wrong. It’s better for you to leave this type of problem to the professionals. To check if the gauge is faulty, an expert will have to rule out all other reasons for the boiler’s change in pressure.

Having a low boiler pressure is a frustrating hindrance to any residential or commercial property owner. But there’s always a way to resolve the problem.
