There are several reasons that there might be a drop in boiler pressure. One is a lack of water pressure in the boiler and it should  be established from the outset if this is the case. If not it could well be for one of the following reasons;

  • Faulty release valve: If there’s an issue with your boiler’s pressure release valve or overflow, you will likely experience a consistent drop in pressure.
  • Leaks: There may be a leak somewhere in the system that’s causing your boiler to lose water, which will subsequently lead to a drop in pressure.
  • Boiler age: if your boiler is between 20 to 25 years old, there’s a good chance that wear and tear (due to prolonged usage) has affected the vessel or other components.

If you are experiencing an issue with your boiler contact one of our engineers who would be happy to discuss the matter further with you.
