For most homeowners, plumbing is out of sight and out of mind - which is why one of the main indications that something is amiss is an abnormal noise coming from your plumbing. These symptoms may be hard to diagnose but they could be a sign of a more serious issue in your plumbing system.

The easiest way to get to the source of the problem is with a plumbing inspection. For homeowners in and around the Pearland area, Epic Plumbing. is here to help.

Pipes Whistle When You Run The Sink

In order for water to run throughout your home’s plumbing system, there is a certain amount of water pressure needed. While low water pressure is a common issue that may be caused by a clog or some other plumbing damage, high water pressure could also be a problem.

If you open a faucet or run water anywhere in your home, and you’re hearing a high pitched whistle, then chances are the problem is excess water pressure.

If left unchecked, this excess pressure can actually rupture your plumbing, leading to significant water damage to your home. For some homes, this can be done within the plumbing system, but in other scenarios, the excess pressure may stem from the actual city water mains, and the pressure would need to be adjusted in that area instead.

Running Hot Water is Causing Banging or Knocking Pipes

You rely on your hot water for your comfort and for use in appliances like dishwashers and washing machines. So it’s going to a be a problem if anytime you go run the hot water you hear banging coming from the plumbing. There are a few common causes for this including:

  • Hard Water Buildup: Hard water is a mineral deposit that turns into scale buildup, which is often caused by the use of unfiltered water. As the water comes in contact with that scale it creates surging pressure in the tank.
  • Natural Gas Issues: Although natural gas can be a great way to save money on energy costs - it could also open your home to other risks. If you’re hearing banging or popping noises, particularly when the water heater is kicking off, it may be an issue with the gas lines. A plumbing inspection will be able to determine whether or not there’s a gas leak in your home.
  • Thermal Expansion: Things can get chilly in Pearland - and when they do, your water heater may fall susceptible to thermal expansion. This is essentially what occurs when your reservoir runs out of hot water. As the metal expands it could be causing the banging or knocking sounds in your plumbing.

The best way to determine what’s causing the noise is to work with your local plumbers. They will be able to help you pinpoint the source of the problem and get to work fixing it.

Drain Gurgling And Continuous Running Water

A water leak or sewer line issue can both cause these noises. As the pressure drops in your plumbing system, it will create a large drop in pressure, which leads to that gurgling noise.

Additionally, if you’re hearing gurgling noises, you may also notice foul odors, which can be an indication that the problem is in your sewer line.

Running water, on the other hand, is mainly caused by water leaks. Even though you may not have a sink or fixture open - the water is still leaking out of your pipes, leading to the noise.

Although you may have a general idea of what’s causing the problem, the best way to get to the bottom of it is working with a reliable plumber. At Epic Plumbing. we offer detailed plumbing inspections that can help diagnose your plumbing issues and find you a long-lasting solution.
