The Facts about Water Hammer

Have you ever been disturbed by a loud knocking noise in your pipes? When this happens while you are comfortable resting at home, it may come as a bit of a shock. In fact, when homeowners believe that paranormal activity has occurred in a home, they often list knocking on the pipes as one of the reasons. But this noise actually has a far more probable explanation: water hammer.

Get the facts about water hammer in today’s post, and be sure to schedule plumbing repair in Essex, VT with the friendly technicians at Red Rock Mechanical at the first sign of pipe problems.

“Water Hammer” Describes a Particular Plumbing Event

Many people use the word “water hammer” to describe any strange noise in a plumbing system, assuming it’s a fairly universal term. But it turns out that water hammer is actually a specific event caused by changes to your plumbing system or an imbalance in the pipes. Water hammer occurs when there is a sudden change of pressure. If water is forced to stop suddenly, a wave of pressure forces it to change direction and knock against the pipes. This may happen because of a waterlogged air chamber or a valve that shuts too quickly.

Water Hammer May Severely Damage the Pipes

This change in momentum can actually cause some detriment to your pipes. The vibration that follows from the pressure wave may knock fittings loose and could even force a pipe to burst. This will result in costly renovations, an enormous mess, and the potential for mold growth.

What Works In Some Plumbing Systems May Not Work for Yours

Although many plumbing systems are fitted with air chambers that work to provide a cushion of air to protect against water hammer, these may become waterlogged and will need to be purged. In other cases, there are not enough protective features in your plumbing to safeguard against water hammer, and a technician may recommend any of several solutions. A new air chamber may not be possible because they are quite large, so your technician may prefer to install an arrester part. Sometimes, plumbers choose instead to install slowly-shutting valves or even new pipes.
