“What’s that hissing sound?” “Why is there a wet spot in the yard? “Do you smell gas?” “Why is the water bill so high?”

We hope that you never have to experience a serious gas or water line repair. But the majority of homeowners will face these issues sooner or later. Being educated and prepared is the best way to guard the investment of your home from leaks.

Legacy Plumbing offers advanced water leak detection, safety valve service/replacement, slab leak diagnosis/repair, and gas leak locating/repair.

Water and Gas Lines in DFW​

Many homes in North Dallas rely on natural gas for heat, which is more affordable than electric utility rates. According to Redfin results for Frisco, in the past year 1,059 homes were sold with gas connections while 2,694 homes did not mention gas as a fuel source. 

Older homes are more likely to have gas connections for water heaters, gas stoves, fireplaces and even gas dryers. Gas lines are important to locate within the home, especially when remodeling. Most home inspectors will check if gas lines are properly capped off or connected to an appliance. A gas line plumber can help with new connections in the home and check for leaks and repairs.

Water lines refer to the underground pipes that run from the water main (at the street or curbside) to below the slab foundation and up through the home. Water lines bring potable water into the home and a water meter measures overall usage.

Many homeowners are surprised to learn that water line leaks and repairs in the yard are their responsibility and not the city or utility company. Out of sight and out of mind, underground water lines that leak or break are an emergency that can result in thousands of dollars of damage.


Water Leak Detection and Repair

In the majority of DFW homes built between 1960 and 2010, the water lines under the slab and in the walls are made out of copper. The water lines that run through the yard can be made of copper or different types of plastic. Copper is a tried and true material for water lines, but it has weaknesses. Pinhole leaks and weak solder connections are common modes of failure, often caused by poor installation practices.

The plastic water lines can range from extremely sturdy and reliable to a disaster waiting to happen depending on the specific material. Modern homes are built with plastic PEX water lines. These are very reliable, but different fittings and fasteners manufactured for them have varying degrees of trustworthiness.

Regardless of the material, we have all of the tools and parts on our fully-stocked trucks to locate and repair leaks in the yard or the house.

PRV & Water lines 1

Pressure-Reducing Valves

Many houses in the North DFW area are built with Pressure-Reducing Valves (PRV) on the main water line. These valves protect the plumbing system in your home from the excessively high water pressure delivered by some municipalities. These valves typically only last between 8-15 years before they start to cause problems. When they do, they can cause weird issues with the water pressure and odd noises when different plumbing fixtures are turned on.

Whether you have a PRV that needs to be replaced, a PRV installed because of high water pressure, or just need to know whether you have a PRV and where it’s located - Legacy plumbing can help!

Slab Leaks

A majority of residential properties in DFW are built on a slab foundation, which can pose challenges for accessing plumbing.Pinhole leaks in the copper water lines and broken sewer piping under the slab can result in major foundation damage if not corrected quickly.

Slab leak diagnosis and repair is a more advanced subset of plumbing skills. Fortunately, at Legacy Plumbing, our team has extensive training and decades of experience repairing slab leaks. While some plumbers take the one-dimensional approach of jackhammering the slab every time to fix leaks, we step back and go through all of the different repair options available and can discuss the pros and cons of each.

Gas Leak

Gas Leak Repair/Installation

Gas lines in most houses built before the mid-2000s were made of a steel, threaded piping called black iron. In more modern homes, this material has been mostly replaced with a flexible, corrugated stainless steel tubing called CSST. Both of these materials have their strengths and weaknesses. CSST is much more prone to puncture if improperly shielded. Black iron is liable to rust away if exposed to a constant source of dampness.

Fortunately, natural gas is infused with such a strong odor that most of the time even small leaks are quickly brought to your attention. Because of its flammable and explosive nature, natural gas is rightly very intimidating. Fortunately, Legacy licensed plumbers are trained in all of the proper codes and procedures to make any repairs you may need or even to install new gas lines on your existing system.

After finding the source, the repair was made professionally and used materials to help mitigate / prevent the potential recurrence of a similar event in the given area. Additionally, before turning on the main line from the street a description of the next series of events were described to us (the owner) ensuring how the work would be proven out / validated not only for the area of immediate interest / repair but also how strategic steps would be taken to discern if there were any additional areas of interest that would need repair. The work of the Legacy Plumbing, Inc. team’s execution of validation was flawless.

I had a leak from my recirculating pump line. Luis came out promptly. He wore a mask, gloves, according to Covid 19 protocol. He was very thorough, efficient. He also replaced water pressure tank. He replaced it whole lot better than the builder’s plumber. He explained everything so I knew what he was doing. Highly recommend Legacy Plumbing. I’d definitely will be asking for Luis in the future.
