We can get down to the root of the problem and fix it so that it doesn’t happen again. You can keep reading to learn more about water hammer, what it is, and why it is so bad for your boiler.

What is Water Hammer?

Water hammer is a phenomenon that happens when the water inside of a plumbing system like your boiler suddenly begins to move in the opposite direction. The force of this change can make a very loud noise, similar to the banging of a hammer, and that’s exactly how the phenomenon got its name.

Potential Repercussions

Water hammer is not just unusual or inconvenient. It can actually be very damaging to your boiler. Plus once water hammer occurs, you have to address the problem or else it may keep happening. The pressure from water hammer happening can cause damage to the attached pipes, gaskets, and gauges on your boiler. It can lead to leaks or changes in how your boiler operates. 

If you hear a sudden loud sound coming from your boiler and then notice any unusual changes in operation, it’s important to call for service right away. Allowing water hammer to continue or leaving the problem unaddressed can mean that you will have to replace your entire boiler sooner than you anticipated.

Addressing Water Hammer

When our team arrives at your house for a boiler repair appointment, we will assess the system for signs of damage. If there are any components that need to be repaired or replaced, we will do so. In order to reverse the effects of water hammer and reset your boiler we have to drain the water lines and then allow them to refill.

Preventing Water Hammer 

If water hammer happens continually inside of your boiler, we can take steps to prevent it. Loose pipes, clogged chambers and closed valves can all contribute to water hammer. If our efforts to repair and reverse the phenomenon don’t work, we can install some add-ons to your boiler. For example, we may add a shock absorber or water hammer arrestor so that your boiler can operate as usual without you having to worry about the repercussions of water hammer.
