Water Leak Detection & Repair in Dallas, GA

Tracing a hidden water leak gets much simpler once one question is answered: is the water coming from the supply side or the drain side of the plumbing? Supply pipes hold water under pressure day and night, so many supply leaks continue between fixture uses, although some are intermittent. Drain pipes carry water only when something runs or empties, so a drain leak comes and goes with use. Alpha Plumbing and Sewer starts a Dallas leak call by placing the leak in one of those two groups, because the testing and the repair differ from there on.

How supply leaks behave

• The water meter moves even with every fixture turned off, once automatic uses such as an ice maker or softener are ruled out.
• Dampness holds steady or keeps spreading whether or not anyone has used water.
• A faint hiss or rush may be audible in a quiet house, especially late at night.
• Pressure at nearby fixtures can sag if the leak is large.
• Escaping supply water can become contaminated after contacting building materials. Avoid touching hot or standing water to identify its source.

How drain leaks behave

• The meter stays still with fixtures off, because drain water was already counted on its way in.
• Stains or drips appear after a shower, a load of laundry, a dishwasher cycle or a flush.
• The water may be cloudy or soapy, or it may smell.
• Gurgling or slow draining sometimes comes along with it when the pipe is cracked or partly blocked.

Drain leaks inside walls or under floors are handled through drain repair, and they seldom call for the listening equipment used on pressurized lines.

Useful observations before the visit

1. Stop all water use and look at the leak indicator on the meter.
2. If it moves, suspect the supply side or a running toilet. If it stays still, go to the next step.
3. Record which fixture was last used before the stain appeared; do not run it again just to reproduce the leak.
4. If the dampness grows only after draining, the drain line, the fixture's seal or the trap is the likely source.

Finding a pressurized leak

For supply leaks, the technician puts the line pressure to work. Water forced through a crack makes noise, so acoustic equipment can follow the route of a pipe and help pick out the loudest point, which is then checked against other readings. Closing branch valves shows which section is losing water, and on hot lines a thermal camera may reveal a warm streak behind drywall. Moisture readings help map the affected area, but water can travel away from the actual leak before it becomes visible. Our Georgia leak detection overview explains these locating tools at more length.

Fixing each type

A supply line repair usually means opening a small area, replacing the damaged section with compatible pipe and fittings, and repressurizing to check the new joints. A drain repair can be as modest as resealing a slip joint under a sink or as involved as replacing a cracked fitting inside a wall or beneath a slab. When supply pipe has sprung leaks in several places, whole house repiping is worth weighing against a series of separate repairs.

Common questions about supply and drain leaks

Why does my water meter stay still if I can see a leak?

Because the meter only counts water on its way in. Once water has gone through a faucet or shower and starts escaping from the drain below, it has already been measured, so nothing registers while the fixtures are off. That is why a visible leak beside a motionless dial makes drains, fixture seals and tile more likely than the pressurized lines, though a very slow supply leak can be too small for a short meter test to show.

Is a drain leak less urgent than a supply leak?

The damage depends on the amount of water, its contamination and where it goes; a drain leak is not automatically less urgent. Still, drain water is not clean, and a slow drain leak inside a wall can rot framing over time. Stop using the fixture involved and get it repaired soon. A supply leak cannot be paused that way except by closing a valve.

Can one leak be on both sides?

It happens. A toilet can leak from its supply connection and its wax seal at the same time, and one sink cabinet can hide both a dripping stop valve and a loose drain joint. Testing each part separately, with the meter and with controlled use of the fixture, keeps one problem from masking the other so both get fixed.
