Why are My Drain Pipes Making Noise?


A noisy drainpipe can be much more than a minor inconvenience. In most cases there may be an underlying problem that needs to be alleviated as soon as possible, before extensive damage to the piping system as occurred. Unfortunately though, many homeowners ignore a noisy drain pipe and as such, accumulate a mountain of plumbing repair bills when the problem gets worse and causes a variety of unforeseen damages such as burst pipes, leaks and drain back ups. Here are some of the most common causes of noisy drainpipes along with some solutions that you can utilize to alleviate the problem temporarily.

Ticking And Creaking

If you notice that your drainpipes make ticking and creaking noises within your home, every time you utilize hot water, for the most part this isn’t something that you should worry about. In general, copper pipes expand when it is hot. As such, the ticking and creaking noises you hear, may be as a result of the pipes expanding. One way you can neutralize the sounds associated with expanding copper pipes though, is to wrap a sufficient amount of insulation around the pipes, which will help to muffle the sounds.

Popping And Rattling 

One of the most common noises that many homeowners experience with their pipelines is a popping and rattling sound. As is the case with all bodies of water, tap water has an abundance of minerals within it. In some cases, these microscopic minerals gradually build up and accumulate on some of the internal sections of your pipe. As such, when heated water runs over these build up of minerals, they cause air bubbles to burst and pop, thus causing a popping and rattling noise, due to the fact that the motion that the burst air bubbles cause, may rattle the pipe causing it to hit nearby pipes or other objects that are within close proximity of it. One way you can stop the pipe from vibrating against other objects is to secure it with a strap or by adding cushion around the pipes.

Banging Noises

If your pipes are making banging noises, you need to contact a plumber as soon as possible. A banging noise is usually indicative of a broken valve and faucets, damage within the heating system and loose piping. Essentially, the banging that you hear more than likely may be due to a broken mechanism in your home’s piping infrastructure. Due to the complexity of plumbing systems as a whole, it is extremely difficult for an inexperienced individual to pinpoint the exact reason of a banging noise. As such, by contacting a plumber as soon as possible, you will essentially minimize the impact that the faulty or broken mechanism will have on your overall plumbing infrastructure.

It’s important to note, that noisy drainpipes usually indicate an internal problem with your pipeline system. As such, even though there may be some temporary solutions that are available to you, you need to ensure that you contact a plumber regardless, so that they can pinpoint the exact root of the problem before you have major problems.
