The boiler pressure should maintain a constant level as the boiler heats water and keeps it warm. These building heating systems are strong and durable, lasting for many years if they are well maintained. Damaged or broken parts on a boiler can lead to carbon monoxide leaks. This deadly gas can cause serious injury and death. One importance maintenance step is checking the boiler pressure levels. Doing this on a regular basis will keep your home warm and safe.

Step 1 – Locating the Boiler Pressure Gauge

All boilers have a gauge that indicates the pressure inside. The gauge is generally found on the side of the boiler. This device will tell the homeowner if the pressure in the boiler is excessive.

Step 2 – Reading the Boiler Pressure Gauge

The pressure gauge on smaller home boilers should maintain a level of twelve to fifteen pounds. In the event that the boiler pressure is too high, a release valve can be turned to lessen the pressure.

Step 3 – Getting Professional Assistance

If the pressure increases immediately after releasing the valve, a professional service person needs to be contacted regarding the situation. Consider having the pressure regulator adjusted in order to keep the pressure in the boiler at a lower level. Read the owner's manual provided by the manufacturer of your boiler for the necessary information to adjust your pressure regulator.
