Septic Pumping in Northeast Texas

A tank that’s due, or one that’s already at the lid, needs a pump-out and a look inside. Underwood pumps septic tanks across Collin, Grayson, Fannin, Hunt, and Lamar counties and tells you what the baffles look like.

Tank at the Lid? Call and We'll Schedule a Pump-Out.

Don’t keep running water into a full tank. Call (903) 449-1677 and we’ll get the truck on the schedule.

Our Septic Pumping Process

Call or request a quote: Where the lids are, when it was last pumped, and whether drains are already slow.

Locate and open: We find the lids. If they’re buried, we say so before the truck is sitting in the driveway.

Pump the tank: The truck is ours. You aren’t waiting on a subcontractor’s calendar.

Look at the baffles: A pump-out that ignores a missing outlet tee just schedules the next backup.

Note what we saw: You hear the level, the baffles, and whether a repair should be planned.

Seat the lids: Lids back on, risers checked, the yard left so you can find them next time.

The Underwood Septic Standard

How often should a tank be pumped?

For most houses here, every three to five years. A full house, a garbage disposal, or a small tank shortens that. We’ll tell you what your tank looks like, not a generic reminder.

Do you pump and inspect, or only pump?

We pump and we look. Baffles, the outlet tee, and the level. If something is broken, you hear it that day.

Where do you pump septic tanks?

Collin, Grayson, Fannin, Hunt, and Lamar counties. The truck runs out of the same company as the plumbers, from McKinney, Bonham, and Sherman.

Can you pump on short notice?

When the tank is at the lid, we treat it as a priority and get the truck moving, evenings included. Routine pump-outs are scheduled.

Is pumping part of the membership?

Membership plans are built around keeping the system maintained. Ask which plan includes pumping, or see the Memberships page. We won’t guess your plan on this page.

Why Underwood

Why Northeast Texas Calls Underwood for Septic Pumping.

We Communicate.

You talk to the company that owns the truck. We pick up, and the schedule is ours.

Stocked Trucks, One Trip.

The truck is stocked for the pump-outs we run, so a routine tank doesn’t become a two-day event.

Plumbing and Septic, One Call.

If the backup is the house sewer and not the tank, the plumbers are the same company.

Seasoned Service Professionals

TCEQ registered, with years of septic work in Collin, Grayson, Fannin, Hunt, and Lamar counties.

What We Fix

Septic Pumping, Start to Finish

Scheduled pump-outs: on a cadence that matches the house, not a postcard from a company that doesn't know the tank.
Full tanks: pumped when sewage is at the lid, then the baffles checked.
Buried lids: located and, if you want, brought to grade with a riser so this is the last search.
Outlet tees: noted, and replaced when solids are heading for the field.
Reports: you hear what was in the tank and what should happen next.
Follow-on repairs: scheduled with the same company if the pump-out shows a failure.

Financing Available

We offer flexible payment options for our services.

Signs It's Time to Pump the Septic Tank

It's been more than three years, and nobody remembers the last pump-out.
Drains are slow in the whole house.
A smell near the lids after rain.
The lowest drain in the house gurgles.
You're listing the house and the buyer asked for a pump-out.
Sewage is at the lid. That's past 'schedule it.'

Septic pumping for homes around McKinney, Bonham, Sherman, Denison, Greenville, Paris, and the county roads between.

 Trustindex verifies that the original source of the review is Google. I needed a sewer tank cover replaced due to it being hit by the lawnmower. These guy fixed it in less than 30 minutes.
Chad also suggested putting landscaping stuff around the 4 tanks to prevent this happening again. Totally happy with their service.
