A heavy North Texas rainstorm can quickly overwhelm local drainage and flood finished basements and low slab-on-grade floors. Herndon McFarland Plumbing has sized and installed sump systems across DFW since 1995. We match pump capacity to the water moving beneath local homes.

We put protection in new systems, replacements, proper sizing, and backup add-ons for homeowners deciding to defend before the next storm.
For homes without below-grade water control, we cut and form the pit, set the basin, and install a primary pump matched to inflow. You get a sealed, code-conscious system to move water out before it reaches the floor.
Pumps wear out and often fail during storms. We remove the aging unit, inspect the pit and discharge, and install a properly rated replacement.
Most installers skip this part. We measure discharge height, estimate how much water may enter, and select a pump that can clear it fast, keeping the pit from overflowing.
North TX storms can knock out power when you need it most. A backup unit keeps water moving during an outage. We wire and test it as part of installing a sump pump in DFW.
A pump is only as good as the basin around it. We set a properly sized pit with gravel bedding and a sealed lid to control humidity and keep debris out.
We carry the discharge well away from the foundation and fit a quality check valve to prevent pumped water from draining back into the pit. It prevents the motor from cycling too often.
The reason lower levels take on water is the intensity of the rain, not just the amount. NOAA Atlas 14, Volume 11 is the official government source of precipitation frequency data for TX. Its 2018 update raised the rainfall depths that define extreme storms across the state.
A heavy DFW storm can deliver many inches of rain in a single day. The ground cannot absorb that volume quickly. The Blackland clay under much of DFW has low permeability; high-intensity rain does not soak in. It stays near the surface, and the local water table climbs against below-grade walls and slabs.
As that water builds, the pressure pushes through cold joints, hairline cracks, and the seam where the floor meets the wall. That pressure, not a plumbing leak, is what fills a pit and floods a finished space.
A system only beats that pressure if sized to the storm. We calculate the required pump flow rate based on your total discharge head, set the pit volume to match, and add battery backup. This keeps your basement dry and prevents midnight plumbing emergencies.
Some plumbing decisions are not simple. Chris Roland faced a tangled situation and needed options laid out clearly, not a rushed upsell. He came to us, weighing his options for a complex setup, and wanted complete quotes before committing.
He noted:
“Herndon-McFarland was very thorough and professional when helping me decide what to do with my extremely complicated plumbing situation. Their quotes were quick and thorough… I’d recommend them to anyone who asks.”
That options approach is exactly how we handle sump pump installs in DFW, where the right system depends on your home, not a template. Read Chris’s full Google review.
When protecting a home from the next storm, a crew that shows up when promised and works carefully matters as much as the parts. Shonne Landry scheduled the service and saw the appointment go smoothly.
She wrote:
“Chris was on time (even a little early) and the plumbing service was excellent. He was thorough and did a good job. I will use them again.”
Punctual, thorough work is the standard we hold for every install, backed by same-day availability when a storm season problem cannot wait. Read Shonne’s full Google review.

If you already have a unit acting up, our sump pump repair team handles that separately. You can also explore our full plumbing services while we are on site.
Common signs include water pooling at a lower level after heavy rain, persistent dampness or a musty odor near the slab, and efflorescence on lower walls. If you have seen water once, the conditions that let it in are still there, and a sized system is the fix.
We start with an on-site assessment to measure discharge height and estimate how fast water can enter. We set the pit and basin, install a pump, route the discharge away from the foundation, fit a check valve, and test the full cycle.
For most DFW homes, yes. The storms can cut power. A primary pump with no backup can be useless during the worst hour. A battery backup keeps water moving through an outage and is a valuable add-on.
If the unit is more than 7 to 10 years old, has failed once already, or is undersized for your inflow, replacement is usually the better option. If it is newer and the issue is a stuck float or a bad check valve, repair may be enough, and our repair team can advise.
North TX rain falls heavily, and the low-permeability Blackland clay cannot absorb it fast enough. The local water table rises, and hydrostatic pressure forces it through joints and cracks. A correctly sized sump system relieves that pressure by pumping water out faster.
Book online, and we will set up an assessment, provide a written estimate with upfront pricing, and schedule the install. Same-day availability is often possible when timing is tight.
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.
