Reasons Why Your Boiler May Start To Leak


If you live in a cold climate, then you want to make sure your boiler is working perfectly. Leaks not only cause your boiler to be less effective, but it can also cause damage to the surrounding area. Therefore, you should track down and stop any leaks as soon as possible. However, determining the exact cause for the leak may be difficult. Here are four of the more common reasons why your boiler is dripping or leaking.

Bad Seals

Any type of sealant can break apart with age, but the seals around the boiler pump are usually where most boiler seal leaks originate. In many cases, all that is needed is a re-seal around the pump, and you're good to go.

Very rarely does the entire pump need replacing unless there is excessive corrosion. You should have an inspection done first to rule out any other issues that may be contributing to the deterioration of the seals.

High Pressure

If you see leaks coming from around the pressure valve, it may mean that the valve is not working properly, and your pressure is too high. Another cause of high pressure is limescale buildup or other sediment causing a backup down the line. High pressure can also cause leaks in other areas including around the hose fittings or at the pump.

High Temperature

High temperatures can cause problems with pressure as well as speed up the rate of corrosion and sediment buildup. Check your boiler's temperature, make sure it's in the correct range, and adjust if necessary. You want the temperature to be near or just below boiling but not actually at the boiling temperature of 212 degrees. You may also want to look into whether or not your thermostat is working correctly.


Corrosion from age or contaminants in the water can certainly cause your boiler to leak. Aging and metal fatigue from pressure changes cause small cracks to form.

Corrosion leaks are common around connection points, pipes, or even the body of the boiler. Small leaks can often be patched up or repaired with replacement parts, but if you have too many cracks, it may indicate a need for complete boiler replacement.

Because your boiler is important and a new boiler is often a big expense, you should not attempt to fix the problem yourself. Instead, hire a heating, ventilation, and air conditioning service such as R & B Inc Heating & Air Conditioning to diagnose and fix the problem. While they're evaluating your boiler, they can also do an inspection of the rest of your system to determine if there are any potential problems down the road.

Talking About Electric Heating Systems

Hi there, my name is Shelley. Welcome to my site about electric heating systems. Electric heat has recently fallen out of favor due to the efficiency of natural gas systems. Electric heat is still suitable for small buildings that do not need the high temps provided by upgraded systems. I will use this site to explore all of the building types that can benefit from electric heating systems. I will also share information about system components, installations and repairs. I welcome you to come by often to learn more about this exciting topic. Thanks for coming by. See you soon.
