Symptoms, Explained
Common Plumbing Problems in Brentwood, TN
Every plumbing problem starts as a symptom: a sound, a smell, a bill, or a puddle. This guide explains the common ones in plain language, what they usually mean, and when to call.

Water Bill Suddenly High
The most common hidden-leak sign in Brentwood. A pinhole leak in a copper line, a running toilet, or a slab leak can waste hundreds of gallons a month with no visible water. Check the meter leak indicator with all taps off. If it moves, water is going somewhere it should not. See leak detection.
Sound of Running Water With Taps Off
If you hear water moving in a quiet house, a supply line is leaking somewhere, often under the slab or behind a wall. A warm spot on the floor points to a hot-water line. See slab leak repair.
Slow or Backed-Up Drains
One slow drain is usually local: grease in a kitchen line, hair in a bathroom drain. Every drain slow at once points to the main line, and a backup into a tub points to a sewer problem. See drain cleaning and sewer camera inspection.
No Hot Water or a Rumbling Heater
Brentwood hard water builds scale in tank heaters, making them rumble, pop, and heat poorly. A pilot that will not stay lit, an element that fails, or a tank that leaks are the other common faults. See water heater repair.
Running, Rocking, or Leaking Toilet
A running toilet is usually a worn flapper. A rocking toilet is a worn seal or a low flange, and water at the base means the floor underneath is at risk. See toilet repair.
Low Water Pressure
Low pressure at one fixture is often a scaled aerator or cartridge. Low pressure through the whole house can mean a failing pressure regulator, a partially closed valve, or a hidden leak. Check the easy fixes first, then call us if the whole house is affected.
Gas Smell
Leave the house, do not flip switches, and call the gas company and 911 from outside. Once cleared, we can check the line. See gas line repair.
Frequently Asked Questions
My water bill jumped. What do I check first?
Check the meter leak indicator with all taps off. If it moves, you have a leak. Note the reading, wait an hour, and read it again, then call us.
Is a gurgling drain serious?
It often means a partial blockage or a vent problem. It is worth a look before it becomes a full backup.
Why does my shower go hot then cold?
A worn shower cartridge or a pressure imbalance between hot and cold lines is often the cause. See our shower repair page.
Can I use drain cleaner?
It can clear a light clog, but strong chemicals can damage older pipes. If the drain is still slow after one try, stop and call us.
