Boiler Losing Pressure? You may need the UKs Leak Detection Specialists

Central-heating-problemsMy boiler keeps on losing pressure? What could be the problem? This is a fairly common question than we normally encounter among our clients. There could be a myriad of reasons why your boiler is losing pressure. From faulty pressure release valves to leaking radiators and piping.

Before we just into the major causes of pressure loss, let us look at what it means with the boiler losing pressure. The first method is where the boiler loses pressure when the heating system is on. The boiler expands and increases pressure which suddenly drops. The second is a slow pressure loss which mostly occurs overnight. The meter gauge is not seen drastically drop but the pressure is lost over a period of time.

Common Causes of Pressure Loss in Boilers

Most common causes are as a result of leaks in the boiler systems and piping. Here are some of the causes;

  1. Leak in the pressure release valve

The pressure release valve notices abnormal changes in the system and adjusts accordingly. A faulty pressure release valve will lead to pressure loss which can be easily identified. If you notice water coming out of the discharge pipe which runs externally, most probably you have a faulty release valve.

  1. Leaking radiators and radiator valves

This is the most common culprit to pressure loss in boilers. Old and rusty radiators are prone to corrosion which may lead to leaks. Even the tiniest of leaks in radiators would cause loss of pressure. Check out if there is water escaping from the radiator and its plates. A small weep on the radiator valves is indicative enough of the continuous loss of pressure.

  1. Leaky heating pipework

A hole in any of the connecting pipes would lead to a loss in pressure. A leak in the pipes can be identified through a stain in the ceiling, damp and soggy floors, a hole in the radiator and many more. Leaky soldier joints holding the pipes and the boiler together may also be a reason.

  1. Faulty expansion vessel

The expansion vessel may function improperly as a result of a leaking Schroeder valve. A leak in a faulty valve causes increased pressure to be released leading to pressure loss. The pressure loss could also be caused by a worn out diaphragm that has been degraded with time.

Why do you do after realizing about the leaks?

DIY or Professional Leak Detectors.

Getting to check for leaks in boilers is not an easy task. Plus, if your boiler is losing pressure, there is a good chance that you have been asked to increase the pressure using the filling loop. Our advice, dont! Fight the urge to try and solve it on your own and call in leak detection and repair experts. Why? One is because you are dealing with scalding hot water and gases here. It may turn messy if not handled correctly.

Secondly, the inner parts of the boiler are made to precision to prevent malfunctions. If you tamper with the boiler, it may lead to further damage and worsen the conditions. Call in a reputable leak detection company to come to check out your boiler and identify the existing problem
