Addison does not treat its own water. Every gallon that reaches a tap here is bought finished from the City of Dallas, then carried the last stretch by the town’s mains and by whatever piping sits inside the building. Herndon McFarland Plumbing has worked on that last stretch since 1995, from a shop inside the town limits on Billy Mitchell Drive. Our team brings over 150 years of combined plumbing experience to the part of the system Addison does not own.

Addison sends us a mix no residential-only company handles well: houses, low-rise offices, restaurants, and a lot of multifamily. We kept the trade wide enough to take all of it.
Our own licensed technicians do all of it. That is what lets us guarantee the labor rather than pass a complaint to a subcontractor. See the full list of services.
Addison runs no treatment plant. The Town of Addison 2024 water quality report states that the town purchases its water entirely from the City of Dallas, which draws surface water from seven sources: the Elm Fork of the Trinity River and lakes Ray Roberts, Lewisville, Grapevine, Ray Hubbard, Tawakoni, and Fork. Dallas treats it at one of three plants. Addison distributes it. Your meter is where the town’s responsibility stops and the building’s plumbing starts.
That line matters here, because two of the complaints Addison residents raise most are not water problems at all. The town’s own report explains the first. A green or blue-green stain in a sink or tub is copper dissolving out of the home’s copper supply piping while water sits unused overnight, and the report names the usual culprit: a leaky faucet or a faulty toilet flush valve keeping water creeping through pipe that should be still. Fix the drip and the stain usually stops coming back.
The second is heat. The same report tells residents to hold water temperature to a maximum of 120 degrees Fahrenheit. Water hotter than that pulls more copper into solution, and a heater running above its need is a heater wearing itself out early.
The report is just as direct about lead, noting that lead in drinking water comes primarily from materials in service lines and home plumbing, and that systems were required to build an inventory of service line materials by October 16, 2024. All three of those sit on the building’s side of the meter. When we open a wall in Addison, we are reading the plumbing, not the utility.
Stained Fixtures That Come Back After Cleaning
Blue-green marks around a drain point at copper piping and a fixture that is not sealing.
Water That Is Hotter Than It Needs to Be
If the tap scalds, the heater is set above what the town recommends and the system is paying for it.
Pressure That Dropped Without a Cause
A failing pressure reducing valve or scale in the supply lines will do this gradually across the whole building.
A Meter That Moves With Everything Off
That is a leak, and under a slab it can run for months before anything shows.

The Town of Addison buys its water entirely from the City of Dallas rather than treating any of its own. Dallas draws surface water from seven sources, the Elm Fork of the Trinity River plus lakes Ray Roberts, Lewisville, Grapevine, Ray Hubbard, Tawakoni, and Fork, and treats it at one of three plants before Addison distributes it. What that means for a homeowner is simple: water quality complaints at the tap usually trace back to the building’s own piping, fixtures, or water heater.
Green or blue-green staining is copper. Small amounts dissolve out of a home’s copper supply piping when water sits in the lines overnight, and the Town of Addison points to two common causes in its water quality report: a leaking faucet or a faulty toilet flush valve that keeps water moving through pipe that should be still, and water heated above 120 degrees Fahrenheit. We check the fixtures first, then the heater setting, then the supply piping, because replacing pipe before ruling out a bad flush valve wastes money.
It depends on the scope. Routine repairs are treated differently from repiping, water heater replacement, gas line work, sewer replacement, or anything that alters the plumbing system. When a permit applies, the work has to meet Addison’s requirements and pass inspection. We determine what the job needs before we start and handle the permitting and the inspection as part of the work, which keeps undocumented plumbing from becoming a problem at resale.
Watch for a water bill that climbed with no change in usage, the sound of running water with every fixture closed, a warm patch on the floor, damp flooring with no source above it, or pressure that fell off across the house. Some slab leaks give almost no warning until damage appears. We use leak detection equipment to locate the line and determine whether it is on the hot or cold side before recommending a repair method, because that decides whether we tunnel, reroute, or open the floor.
Yes. Addison has a large share of offices, restaurants, and multifamily properties, and we handle commercial plumbing and commercial plumbing repair alongside residential work. That includes grease-related drain problems, hydro jetting on lines that clog on a schedule, water heater and booster work, gas piping, and coordination with property managers on access and after-hours scheduling. Having our own excavation crews matters more on commercial sites, where a parking lot or slab often sits over the line that failed.
From slab leaks under the foundation to sewer line repipes, every job is diagnosed, documented, and done right. A look at recent work across North Dallas.
Excellent customer service, very friendly staff from the person taking the call to the staff fixing the repairs. Very trustworthy company. Shaun explained the step-by-step process and provided very fair prices.
Their positive, upbeat, anxious-to-please attitude made the whole process the very best it could be! All of the employees were a pleasure to work with. I highly recommend Herndon McFarland.
Trent and Reggie were the most professional associates entering our home. They treated our home with respect as if it were theirs. We will use this company again because of them and our experience.
