Boiler pressure loss is a common and frustrating issue for both homeowners and commercial property owners, with several potential causes. While pressure loss can happen for various reasons, one of the most concerning is a leak in the central heating system or boiler. If left unresolved, this type of leak can worsen over time, leading to more costly and time consuming repairs. We understand the frustrations that boiler pressure loss can cause, and why it may point to a hidden leak. This post explains more about boiler pressure loss, why it could indicate a hidden leak in your property, and what to do if it occurs.
Why Does Boiler Pressure Loss Potentially Indicate a Hidden Leak?
One of the biggest signs of a hidden leak is persistent boiler pressure loss. If you find yourself frequently topping up the pressure in your boiler, it could be due to water escaping from the system through a hidden leak. A boiler system is a closed loop, meaning that pressure should remain consistent when operating normally.
If the pressure continually drops without any obvious issues like faulty components or recently bled radiators, a hidden internal leak in your pipes or walls could be responsible. Left unchecked, this leak can get worse as time goes on, causing not only damage to your property but also leading to inefficient heating.
How to Pinpoint if a Hidden Internal Leak is the Cause
If you’re dealing with boiler pressure loss, it’s essential to investigate several other potential causes before concluding it’s due to a hidden internal leak. Check for faulty components like the pressure relief valve, which could be releasing excess water. Ensure radiators haven’t been recently bled, as this can also cause a temporary drop in pressure.
Additionally, if your boiler has been serviced recently, there may be an issue with the system’s internal seals or connections. However, if you’ve checked these causes and there’s no visible reason for the pressure drop, it could be a hidden internal leak. In such cases, a professional inspection may be needed to locate the source of the leak within your walls or under flooring.
What Other Signs Point to a Hidden Leak?
Besides boiler pressure loss, there are other signs that could point to a hidden leak in your home. Below are some key indicators;
- Damp or Discoloured Patches on Walls or Ceilings
These patches are often one of the first visible signs of a hidden leak, as water slowly seeps through the walls or ceiling, causing discolouration. Over time, these damp areas can grow and may lead to peeling paint or wallpaper, indicating that water has been accumulating behind the surface for some time. If left unresolved, it could weaken the structure of your walls and lead to more extensive repairs.
- Sudden Spike in Water Bills
A hidden leak can cause a significant, unexplained increase in your water bills, as water continuously escapes from the system without your knowledge. Even a small, slow leak can waste hundreds of litres of water over time, leading to higher costs. If your water usage hasn’t changed but your bills have, it’s a strong indication that there might be a leak somewhere in your home.
- Mould or Mildew Growth
Mould thrives in moist environments, and the presence of unexplained mould or mildew, especially in areas not typically exposed to water, is a red flag. You might find this growth behind furniture, in corners, or along walls and ceilings. In addition to being a sign of a leak, mould can also pose health risks, particularly for people with respiratory conditions or allergies.
- Musty Odours
A musty smell, especially in rooms that don’t typically have high humidity. This odour comes from damp areas where water has been sitting for some time, creating an environment for mould and mildew to thrive. Even if you can’t see any visible damage, the smell alone could point to water pooling behind walls, under floors, or in other concealed areas.
- Flooring Damage
Warped, buckling, or sagging floors are often the result of water pooling underneath the surface, causing the flooring material to weaken and shift. You might notice soft spots, uneven surfaces, or cracks in your tiles, hardwood, or laminate. This type of damage suggests that a leak has been ongoing for a while, and it’s crucial to address it before more extensive structural damage occurs.
