If you have drilled into a gas pipe, you will typically notice a strong, pungent "rotten egg" or sulfur smell, a hissing sound of escaping pressure, or potentially dirt and debris blowing out of the hole.
Damaging a gas pipe can result in: A major fire or explosion which can cause death or serious injury. Disruption to gas supplies and claims for compensation. Claims for costs to repair the damage.
If your drill suddenly dropped forward without resistance, you heard a hiss or spraying sound, or your bit came out covered in metallic shavings, you may have drilled into a pipe. Follow the steps below immediately to check for damage and prevent expensive home repairs.
To avoid drilling into hidden pipes, always map your wall before working. Use a digital stud finder with a live-detection mode to scan for pipes. Never drill directly above or below plumbing fixtures and outlets. Drill slowly with minimal pressure, and use depth-stop tape on your drill bit to avoid going too deep.
Yes, a small gas leak can go unnoticed for long periods because it may not release enough odorant (mercaptan) for the human nose to detect, especially in well-ventilated areas. These slow leaks often fail to produce audible hissing sounds and can remain below detection levels of standard, lower-sensitivity detectors.
No, a faint smell of gas is never considered completely normal or safe.
What common household smells can be mistaken for a gas leak? Sometimes mold, rotten eggs from food, or sewer smells can confuse you. Gas leaks have a distinct rotten egg or sulfur smell added by gas companies.
If the LED light turns red, the device has detected a pipe and you should choose another location. If it turns green, this means there are no metal pipes in this area. The detection device not only shows you the areas to avoid; it can also help you find wooden substructures that you can drill into.
The "135-degree rule" in plumbing states that the total (aggregate) horizontal change in direction for a drainage pipe—specifically trap arms—cannot exceed 135 degrees between the P-trap and the vent. Exceeding 135 degrees (such as using three 45-degree bends or a 90 and two 45s) requires a cleanout because sharp turns hinder flow and cause clogs.
Yes, a house can be entirely rewired without removing or tearing down drywall. Electricians use minimally invasive "fishing" techniques to route cables behind walls, utilizing existing fixtures, attics, and crawl spaces, or by making only a few small, easily patchable holes.
Plumbers use a mix of forensic deduction and specialized technology to locate hidden leaks without tearing apart your home. They generally start by assessing the property for water damage and then utilize advanced tools to pinpoint the exact source.
On average, the cost of plumbing leak detection typically ranges from $75 to $400, depending on factors like where the leak is and the complexity of the problem. Understanding these costs can help you prepare for any unexpected issues and budget accordingly.
For example, a 1-inch pipe allows about 27 gallons per minute (GPM), while a 2-inch pipe handles 100 GPM.
For mild exposure to natural gas or sulfur (mercaptan), symptoms like headaches or nausea usually dissipate within a few hours to a day after moving to fresh air. However, severe oxygen deprivation or exposure to highly toxic byproducts like carbon monoxide can take days or weeks to fully recover from.
In California, fines for damaging a gas line can range from a few hundred to several thousand dollars. Repair costs add up. Fixing a gas line isn't cheap. You'll need to hire professionals, and the job can take days or even weeks.
To determine if your gas tank has been tampered with, inspect the fuel door and cap for physical damage, monitor your fuel gauge for unexpected drops, and check the ground for leaks or puddles. Furthermore, if your engine suddenly misfires, stalls, or is hard to start, your fuel may have been contaminated.
Here are the most common plumbing code violations you might not even realize you have—and why they matter.
Yes, a toilet and a sink can share a vent. In modern plumbing, this is most commonly done using a wet vent, where the sink’s drainpipe also acts as the vent for the toilet.

People often assume signs of a burst pipe are obvious: rushing water sounds and flooded rooms. Unfortunately, ruptured lines can go undetected for weeks, depending on where they are and the severity of the damage.
The term "silent killer gas" almost universally refers to Carbon Monoxide (CO). It is a colorless, odorless, and tasteless gas produced by the incomplete burning of fossil fuels (like wood, coal, propane, and gasoline). It is deadly because it replaces oxygen in your bloodstream, preventing vital organs from functioning.
The first signs of a gas leak usually involve a distinct rotten egg or sulfur smell (due to an added odorant), a persistent hissing or whistling sound near gas lines, or physical symptoms like sudden dizziness, headaches, or nausea.
It is also a good idea to know the signs of a potential CO problem:
