Blog Understanding and Fixing Common Plumbing Noises: A Guide by EMR Plumbing and Heating Aug 02, 2026

As a homeowner, unusual and unexpected plumbing noises can be a cause for concern. However, before calling in the experts, it's useful to understand the root of these sounds and perhaps even fix minor issues yourself. At EMR Plumbing and Heating, we believe in empowering our customers with knowledge so they can handle simple plumbing challenges with confidence.

Plumbing noises are not only unsettling but can also be indicative of larger issues if left unresolved. Identifying the type of noise is the first step towards determining its source and solution.

One of the most common plumbing noises is the dreaded banging sound, often termed as water hammer. This occurs when water abruptly stops or changes direction in the pipes. Usually, this is caused by high water pressure or failing air chambers. If left unchecked, water hammer can cause damage to the pipe joints and valves. To fix this, consider installing a water hammer arrestor or consult a professional to assess and adjust your water pressure.

Rattling pipes are another common complaint. This noise is typically due to loose pipes shaking against the wall or other supports. If you can access the offending pipe, securing it with clamps or foam insulation should resolve the issue. If the noise persists, it might be worth having a plumbing expert take a closer look.

Squealing sounds when you turn on a faucet are often linked to a faulty or worn-out valve. These high-pitched noises can occur when water flows over a deteriorated washer or valve seat. Replacing the worn washer or valve typically resolves the squealing, making your home a quieter and more peaceful environment.

Sometimes, pipes make a gurgling noise, which can be traced back to a drain blockage or a problem with the venting system. This sound often signifies trapped air or water battling to pass through a clogged area. Swift action is recommended here as blockages tend to worsen over time. A drain snake or a plunger can often clear the blockage, but if the problem persists, a plumbing professional might need to inspect your drainage system.

Whistling sounds from pipes generally indicate that the water pressure is too high. Checking and adjusting the pressure reducer valve (PRV) can help regulate the flow. If you do not have a PRV installed, it might be worthwhile to consider having one installed by an expert to protect your plumbing system.
