A disposal that hums but will not turn, leaks under the sink, or has quit needs immediate attention. Herndon McFarland Plumbing has handled garbage disposal installation for DFW homes since 1995. We match the right unit to your kitchen and connect it to code.

Our DFW garbage disposal installation service covers the full job, from selecting the unit to the final test run.
When your sink never had a disposal, we add the mounting assembly, wiring, and drain tie-in. You get a unit chosen for your plumbing.
When an old unit leaks, jams, or runs loud, we remove it and install a new one. This is the moment to move to a higher-horsepower or quieter model.
Disposals run from one-third to one full horsepower. The right pick depends on how much your kitchen cooks and scraps. We size it to grind efficiently without straining the drain.
Most kitchens tie the dishwasher drain to the disposal. That connection must be done correctly to prevent dirty water from flowing back. We set the high loop or air gap as the code requires.
A disposal requires a proper hardwire or plug connection and a switch placed where no one can accidentally reach into the unit. We wire it safely and ensure the setup is secure.
We seal the sink flange, align the P-trap with the correct slope, and run water and the motor before we leave. You see it working and dry.
Before we pick a unit, we consider what DFW tap water does to it. North TX water runs hard, carrying a high load of dissolved calcium and magnesium. The USGS classifies water above 180 milligrams per liter as very hard. Many North TX utilities report similar levels in their annual water quality reports.
Inside a kitchen drain, that scale does not stay still. It bonds with grease and food residue, narrows the line below the disposal, and builds a thin crust in the grind chamber. Over time, an undersized unit or poorly sloped trap accumulates buildup and burns out early.
This is why a disposal install in DFW is more than swapping the box. The right horsepower clears scraps in one pass, and a properly aligned trap with a full downward slope keeps water moving, reducing the chance of scale settling.
We at Herndon McFarland Plumbing size every unit to the household, set the drain to fall correctly, and point out simple flushing habits that slow buildup. As a result, the disposal lasts longer in hard water.
A garbage disposal installation can be quick, but the best plumbers ensure you learn a bit about your kitchen along the way. Suzanne Harris had David handle her install and left with a working unit, practical advice, and a simple way to keep her pipes flowing well.
She wrote:
“David installed a garbage disposal for me. He was very knowledgeable, pleasant, and professional. He even showed me a trick to keep my pipes flowing well. I will definitely use them again.”
That is the standard for every disposal job we run: do the work cleanly, then show you how to get the most life out of the unit. Read Suzanne’s full Google review.
When you hire someone to install an appliance under your sink, the team behind the technician matters as much as the fix. Lynn Jenkinson summed up working with us across the whole job, from start to finish.
She shared:
“Herndon McFarland Plumbing has an outstanding team of friendly and honest professionals who provide exceptional service from start to finish!”

If your unit is borderline, our team can weigh repair versus replacement. You can browse our full range of plumbing services anytime.
Watch for a unit that only hums, frequent resets, leaks under the sink, a returning smell, or a slow drain. Once a disposal is about 10 years old or needs repeated repairs, replacing it usually costs less than chasing problems.
We disconnect the old unit, mount the new disposal, make the electrical connection, tie in the dishwasher drain, and align the trap. Then we run water and the motor to check for leaks before we leave.
A smaller household is often fine with one-third or one-half horsepower; busy kitchens and larger families do better with three-quarters or one horsepower. We help you pick during the visit so you do not overpay or underpay.
A simple jam or tripped reset is worth clearing, but a leaking housing, a seized motor, or an old unit is usually better replaced. For borderline cases, our plumbing maintenance and repair team gives an honest call rather than pushing the bigger job.
Hard North TX water leaves mineral scale that mixes with grease in the drain and grind chamber, narrowing the line and shortening the unit’s life. The right horsepower and a properly sloped trap help the system clear residue rather than hold it.
The fastest way is to book online, and we can schedule a same-day visit when one is available. We send a licensed plumber to install a garbage disposal sized for your kitchen, with upfront pricing first.
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.
