What Pipes Rattling

Pipes Rattling After Shower? Here Are the 2 Possible Reasons

After a tiring day at work, the first thing that you want to do is to take a nice shower before getting into bed.

But after turning off the shower, you hear rattling noises. What’s the reason behind these noises? Rodents? Pests? Ghosts?

There are two possible reasons behind these noises.

Copper pipes

If the sounds you hear come after using the hot water, it is possible that the main reason behind these noises is the copper pipe used in your home’s plumbing system.

Like other types of metals, copper expands and contracts, depending on the temperature. When you hear the pipes rattling after shower with hot water, this simply means that the copper pipes are expanding and rubbing against other components of the plumbing system like the joist, bracket or stud.

Apart from the noises you hear, there is not much you need to worry about. The expansion and contraction of the pipes rarely cause other problems.

Solving this problem can be complicated, especially if the pipes have been installed between the walls. Quite simply, you will need to spend money to have your drywalls removed.  If you have extra money stashed, you can ask your plumber to remove the drywall in the areas where you hear the rattling sounds. Your plumber will then place either foam insulation or foam rubber which will act as a cushion between the pipe and the framing, effectively eliminating the rattling noises you hear.

Alternatively, you can opt for plastic pipes as a replacement for the copper pipes. Plastic pipes do contract and expand, but not enough to cause rattling sounds.

Water hammer

On the other hand, if you hear the noises when you turn the water on and off using either cold or hot water, the main cause of your problem is what is called the water hammer problem.

A water hammer happens when you turn off a faucet or shower quicker than you turned it on. The noise you hear is the result of the sudden movement of water in the pipes. This sudden movement, in turn, causes movements in the pipes, especially if these are not properly secured.

One possible solution to this problem is to install a pressure-reducing valve which lowers the water pressure. Another solution to this problem is to use water hammer arresters. These devices act as a cushion and absorb the energy produced by the movement of the water inside the pipes. Schedule your appointment with us today!
