Your boiler depends on a regular balance of pressure inside its tank and throughout its pipes. To prevent an increase in water pressure, boilers come equipped with an expansion tank and a pressure release valve. Under most circumstances, you should not encounter problems with high water pressure in your boiler.
However, no boiler is problem-proof, and a number of factors can occur to raise the water pressure. This will almost certainly lead to a need for repairs, principally fixing leaks. High water pressure will cause leaking to occur in the boiler tank and all along the pipes. Leaking will threaten the operation of the boiler and will endanger the construction in your home. You need to have leaks fixed immediately, as well as whatever originally caused the boiler’s water pressure to rise to problematic levels.

What causes an increase in water pressure inside a boiler? There are a number of causes, some of which you can take steps to avoid—mostly through regular maintenance.
The pressure relief valve on the boiler can sometimes become blocked, and this will lead to a water pressure increase. The other safety mechanism, the expansion tank, might also suffer damage to its inner membrane which will prevent it from regulating high pressure.
Issues inside the boiler tank itself will often cause high pressure. Corrosion infiltrating the boiler will start to cause an imbalance in the heat inside, since corrosion acts as an insulator. This can raise the temperature in the tank and make the water pressure spike. Sediment deposits that settle at the bottom of the tank (usually entering through breaks in underground pipes) will decrease the available volume in the boiler’s tank, which will also cause overheating and high pressure. Regular maintenance can prevent both of these problems: technicians will replace the anode rod that discourages corrosion and flush out the tank to remove excess sediment.
You should have maintenance done annually on your boiler to catch any of the troubles that might lead to high water pressure. Technicians will also look for leaks that have already started to occur and fix them. You don’t want to have to schedule emergency repairs because of leaking from high water pressure, so make sure you act fast at the first sign of trouble and keep up the regular maintenance.
