FAQ's
Water Leaks
How can I tell if I have a water leak?
Look for signs like unusually high water bills, damp spots or stains on walls/floors, mold growth, musty odors, standing water, unusual landscaping (lush or soggy), or hearing running water when nothing is on.
Can I use my water meter to check for leaks?
Yes—turn off all fixtures and appliances, then watch the meter. If it moves, even slightly, you likely have a leak.
What causes pipes to leak?
Common culprits include corrosion (often from water chemistry), aging components, poor installation, shifting structures, or degraded seals.
Gas Leaks
How can I detect a gas leak?
Natural gas is odorless but mercaptans are added to give it a rotten egg or skunk-like smell. If you detect that odor or hear hissing, evacuate immediately and call emergency services
What are the risks of a gas leak?
Gas leaks can pose serious fire or explosion hazards. They can harm vegetation or animals and reduce oxygen levels, posing health risks.
Who is responsible for inspecting gas lines?
Gas utility companies are required to inspect gas equipment up to and usually including the point of entry into a building, as per federal safety standards.
Sewer Leaks
What causes sewer gas problems indoors?
Sewer gas might enter through dry traps (commonly in infrequently used drains) or blocked vents.
How do plumbers detect sewer gas leaks?
Smoke testing—forcing artificial smoke into sewer lines—helps reveal defects by observing where smoke escapes.
What is a trap primer and why is it important?
A trap primer is a device that adds water to plumbing traps (like floor drains) to maintain a water seal, preventing sewer gas from entering the building.
