4 Not-So-Obvious Signs You Need A Plumber

1. Gurgle - If while you're using one plumbing appliance you hear this bubbling or gurgling sound coming from another plumbing appliance, call in our Sterling, VA plumber quickly. Your sewer line is so clogged that the air in your network is coming up through your plumbing's water. This is a sign that pressure is building and something could burst as a result.

2. Some cold water in your hot shower - You might not think much about a flash of cold water in your hot shower, it might even feel nice. But it's a sign that your water heater has a leak in the dip tube that's responsible for bringing cold water into your water heater so give us a call.

3. A leaky faucet - If you're on a water meter, this could be an incredibly pricey situation. Even if you don't pay for your water it's a tremendous waste of water so get a professional's attention.

4. Your toilet won't stop making noise - This could be a quick fix. First, check that your chain isn't too long and getting in the way of your flapper's seal. Then make sure the chain is hooked up properly. If those aren't the problems, then call in our Sterling, VA plumber as there are a few different possibilities that could be causing this noisy problem.
