Causes For Boiler Leaks
Finding the root cause for a boiler leak is challenging. You need to know where the leak started. Some boilers leak from the bottom and some leak from the inside. Below are some common reasons for boiler leaks.
Pressure Valve: If a boiler is leaking from the pressure valve, this could indicate that there is too much pressure in your boiler. A boiler’s pressure should be between 18-21 PSI. When the pressure is higher than this, it leaks water from the pressure relief valve so that you boiler doesn’t blow up. Limescale and other sediments can cause more pressure to build in your boiler as well. After any obstructions are removed from your boiler, the valves will need to be replaced.
Temperature Valve: When the temperature of the water in your boiler is too high, then water may leak from the temperature valve. There may be an issue with your boiler’s temperature probe.
Corrosion: Many boilers leak due to corrosion or rusting. The corroded or rusted elements within the boiler will cause it to leak. A corroded tank will also cause a leak. If the reason for the leak is due to a corroded element, then it can be replaced. However, if elements and the tank are corroded, like the Revoir’s boiler was, then you will need to install a new boiler. This means that the corrosion and rust has spread to the point beyond repair.
Pipe Fittings: For gas boilers, water may leak around the pipe fittings. If this is the case, then it is possible that your boiler was installed incorrectly.
Boiler Pump: Leaks that originate from the seals of the boiler pump require a replacement or a resealing of the pump in order to correct the problem.
