No more worries about noisy drain pipes! This method is both aesthetically pleasing and soundproof!

Causes of noise

Drain pipes are usually made of PVC. When water flows through them, it hits the pipe wall, causing the pipe wall to vibrate and producing noise, like someone is knocking on the pipe.

General soundproofing methods

The common practice is to wrap the pipes with a layer of yellow glass wool or black insulation cotton, and then seal the sides with soundproofing panels. However, many consumers say that simply wrapping them with soundproofing cotton is not very effective. To provide a clear comparison, @老赵聊音防音 has compared the advantages and disadvantages of several common drain pipe soundproofing methods, making it easier for everyone to choose the best method.

Bricklaying

First, simply wrap the drain pipe with a layer of yellow fiberglass wool, then build bricks around it. The sound insulation is good, the process is simple and sturdy, and then you can tile the outside. This method is common and practical now, durable, and not prone to cracking or warping. Many experienced contractors use this method. The downsides are that it takes up a lot of space and has high maintenance costs later on.

PVC sheet covering drain pipe

This method has been popular for many years because it is moisture-proof, waterproof, and inexpensive, so it is widely used. The downside is that it is not sturdy and can easily break with the slightest bump.

Panel covering drain pipe

The ceiling and drain pipes are installed together using a keel, but the corners and gaps are very fragile and can easily deform or shift with the slightest touch.

Cement board covering the drain pipe

The cement slab is thinner and needs to be fixed with a keel, which makes it very sturdy. However, the temperature in the bathroom is unstable, and the expansion and contraction of the drain pipes due to temperature changes can cause the edges of the cement slab to crack.

Sound insulation cotton wrapped around drain pipes

Experienced installers typically use a combination of soundproofing felt, soundproofing cotton, and more soundproofing felt. This approach first reduces vibration and then reduces sound, aligning with the laws of noise propagation and offering a highly targeted solution. User feedback indicates excellent soundproofing results. The multi-layered soundproofing material combination takes up little space, is formed in one piece, and eliminates subsequent maintenance costs.

These are five commonly used methods for soundproofing drain pipes. After construction and testing, the last method has the best soundproofing effect.
