Hydro jetting cleans a line with water at high pressure, through a hose and a nozzle. It works back along the pipe rather than punching through the middle of a blockage. It is chosen when the wall of the pipe is the problem and not just the obstruction sitting in it.
4L Contracting performs hydro jetting for residential and commercial lines in College Station, Bryan and the nearby Brazos Valley communities. Written pricing comes before authorized work begins.

WHAT A JETTER DOES THAT A CABLE CANNOT
A cable is very good at opening a path through a blockage and getting flow back quickly. For a great many stoppages that is exactly the right tool. Jetting is different. The water works the full circumference of the pipe, and carries the loosened material downstream instead of leaving a coating behind.
The practical difference shows up in how long the line stays clear. A wall that is still coated starts collecting again immediately after a cable clears the opening. That is why some lines keep backing up on a short cycle, even after repeated cabling.
Jetting is not the first answer to every stopped drain. The right tool depends on what is in the line and what the pipe is made of. For clog diagnosis, cabling and a full explanation of why a drain is slow or stopped, see our drain cleaning page.
Cabling
Opens a path through a blockage, restores flow quickly. The right tool for many household stoppages. Does not remove wall coating.
Hydro Jetting
Works the full circumference of the pipe wall. Carries loosened material downstream. Used when the wall itself is the problem.
WHY WE LOOK INSIDE THE LINE BEFORE THE HOSE GOES IN
Putting high pressure water into a line we have not seen is a guess, and the wrong guess is expensive. A sewer camera inspection is run on every job, once the line is clear enough to see and before jetting begins.
The camera travels through the line and shows us the pipe material. It shows the condition of the wall and joints, whether there is a structural defect, and exactly where the trouble sits. That information also tells us whether jetting is appropriate at all for this particular line.
The inspection is recorded. That recording gives an honest before and after comparison, so the customer is not taking our word for the result. You see what the pipe looked like going in and what it looks like after the cleaning is done.
If the camera shows us a pipe that cannot safely take high pressure water, we say so before the hose goes in. The inspection is not optional, and it is not a formality.

Found late Friday evening that I did not have hot water, and it was the weekend... YIKES!! Contacted 4L Contracting LLC; they came out within a couple of hours and had me working in a short time. Lee went above and beyond, letting me know about other problems identified in my attic, a problem with my chimney, and a heating vent installation problem. After he left, I found a water leak in the laundry room ceiling. He turned around and came back to my house. He found the air conditioning drain pipe was backed up. He blew it out the drain pipe, preventing a big disaster. So appreciate his thoroughness and helping me on a Friday after-hours house call. He definitely went above and beyond.
I had a great experience working with 4L Contracting LLC. They were awesome to work with, they were professional, responsive, and clearly knew what they were doing. We had a massive leak that needed immediate attention, and they showed up quickly and handled it efficiently. They not only fixed the issue fast but also made sure everything was done right. I would absolutely recommend them to anyone needing reliable, high quality work!
Used 4L Contracting the first time a couple years ago and since then they have replaced a water heater, reset toilets, replaced water lines, and located and fixed a leak under the house! They have been amazing to work with over the years, I cannot recommend these guys enough!
Water Softener installation Completed! Just wanted to give a shout out to Kurt and Lane on their outstanding customer service today. I hired 4L Contracting LLC to install a water softener in our home. After finding out the water softener I had purchased was missing parts, the job was rescheduled for Monday. I was able to return the water softener and get a replacement fairly quick. So I sent a text to Kurt, letting him know I had done so. He informed me they were nearby and could do the job in about 30 minutes if I could meet them back at my home. I hurried home and in about 2 hours the job was completed. Tonight my wife and I shall enjoy a soft water shower!
My husband and I had a broken pipe in the foundation and it was leaking pretty bad into our hallway, and 4L Contracting came that day we called, assessed the issue, and was back the next day and completely fixed the problem. They were so nice and helpful! I cannot tell you how pleased we were with their service. I recommend 4L Contracting!
My wife and I discovered a water leak coming out of our wall. 4L Contracting LLC came out that day and found where the leak was coming from (copper pipe leaking in the slab), they started working immediately and finished the next day.
These plumbers are honest, knowledgeable and reliable! They helped us fix a leak and answered all our questions about other issues in the house. Highly recommend!
Lee and his guys are Great. Their communication on our projects have been superb! Always letting us know when they will be at the job site. Lee is doing 3 projects for our Airbnb's at one time, and his organization of his paperwork is paramount for us.
SCOPE, WRITTEN PRICING AND WHAT THE CLEANING DOES NOT COVER
The authorized work covers the cleaning described in the written scope. Additional access work, concealed conditions, structural defects, or repairs found along the way are discussed and approved separately before any additional work begins.
Cleaning a line and repairing a line are two different jobs. A clean pipe with a defect in it is still a pipe with a defect in it. If the camera shows a structural problem after cleaning, we explain it and give you a written price for the repair. We wait for your approval before doing anything else.
Our workmanship warranty applies to the work performed. Covered work, exclusions and customer obligations are stated in the written proposal, authorization or invoice. For a full explanation of how written pricing works at 4L Contracting, see our plumbing prices page.
What the cleaning covers
The scope of cleaning described and authorized in writing before work begins. Inspection before and after. Work area protection and cleanup.
What requires a separate authorization
Getting to the heater beyond the original scope, structural repairs, concealed conditions, and any work not described in the original written proposal.
GREASE LINES, RESTAURANTS AND COMMERCIAL KITCHENS
Grease does not sit in a line as a plug. It coats and hardens on the wall. That is why a cable can restore flow through it, and the line still closes back down soon after. Jetting is the method that takes that coating off the wall rather than just opening a channel through it. For the whole picture on kitchen plumbing and the pump out schedule, see restaurant and commercial kitchen plumbing.
For a commercial kitchen, jetting is usually a scheduled job rather than a reaction to a backup. A food service operator who books a regular cleaning interval is really buying predictability. A line that fails during service costs far more than the cleaning did.
4L Contracting handles commercial grease line cleaning in College Station, Bryan and the surrounding area. For a broader look at commercial plumbing services, see our commercial plumbing page.
Scheduled grease line cleaning is available for commercial properties. Written pricing is provided before authorized work begins. Call 979-473-9775 to discuss a cleaning schedule for your property.

ROOTS, BUILDUP AND LINES THAT KEEP COMING BACK
Roots find their way into a line through joints and cracks. Once inside, they catch everything that passes through, and the line builds up from the inside out. Jetting with a root-cutting nozzle clears the intrusion and flushes the debris downstream, which restores the line to working flow.
It is honest to add that jetting removes what is inside the pipe. It does not close the opening the roots came through. That joint or crack is still there after the cleaning, which means roots can begin working back in over time.
A line that needs the same treatment at shortening intervals is telling you something structural. The next step in that case is inspection and a repair conversation rather than more cleaning. If the line itself has failed, sewer line replacement is the page to read. It covers what that work involves and what to expect from the process.
A line may keep backing up on a short cycle after jetting. The follow-up step is then a camera inspection, to determine whether the problem is the pipe itself. We tell you what the camera shows and what the options are before any further work is authorized.
WHEN JETTING IS NOT SAFE ON OLD OR DAMAGED PIPE
Pressure that cleans a sound line can do real damage to one that is deteriorated, collapsed, badly offset, or thin-walled. Older pipe materials in particular have to be assessed before anyone commits to high pressure cleaning. That assessment is what the camera inspection provides.
If we find a line in that condition, we say so and we do not jet it. Turning a blocked line into a broken one helps nobody, and it creates a larger and more expensive problem than the original stoppage.
We would rather lose the job than cause a problem we then have to quote a repair for. That is also the reason the camera inspection is not optional. It is the only way to make a sound decision about whether the pipe can take it.
When the camera shows a pipe that is not a candidate for jetting, we explain what we found and describe the options. Written pricing for any repair work comes before anything else is authorized.

HOW A JETTING VISIT ACTUALLY RUNS
Every hydro jetting visit follows the same sequence: inspect first, clean in stages, confirm the result, explain the findings.
Locate access and set up
The plumber locates a suitable access point, sets up the water supply and equipment, and protects the work area before any cleaning begins.
Inspect the line
A camera inspection is run through the line once it is clear enough to see. It confirms the pipe condition, identifies where the problem sits, and verifies that jetting is appropriate for this pipe.
Clean in stages
The line is cleaned in stages along its length, working the full circumference of the pipe wall and carrying loosened material downstream.
Inspect the result
The camera goes back through after cleaning so the result can be seen rather than assumed. You see the before and after.
Review findings and clean up
Findings are explained to the customer, the work area is cleaned up, and any follow-up recommendations are reviewed. Written pricing covers all authorized work.
Written pricing is provided and authorized before the cleaning work begins. No charges are added after the job without a separate written approval.

Common questions
Is hydro jetting the right answer to every stopped drain?
No. A cable is very good at opening a path through a blockage and getting flow back quickly. For a great many household stoppages that is exactly the right tool. We choose jetting when the wall of the pipe is the problem, not just the obstruction sitting in it.
Why do you look inside the line before the hose goes in?
Putting high pressure water into a line we have not seen is a guess, and the wrong guess is expensive. We run a camera through the line once it is clear enough to see. It shows the pipe material, the condition of the wall and joints, and whether there is a structural defect. It also tells us whether jetting suits this particular line at all.
Can jetting damage an old pipe?
Yes, and that is why we check first. Pressure that cleans a sound line can do real damage to one that is deteriorated, collapsed, badly offset or thin walled. If we find a line in that condition we say so, and we do not jet it. Turning a blocked line into a broken one helps nobody.
Why does grease need jetting rather than a cable?
Grease does not sit in a line as a plug. It coats and hardens on the wall. A cable can restore flow through it and the line still closes back down soon after. Jetting takes that coating off the wall rather than opening a channel through it.
Will jetting stop roots coming back?
Not permanently, and we would rather say so. A root cutting nozzle clears the intrusion and flushes the debris downstream, which restores the line to working flow. It removes what is inside the pipe. It does not close the joint or crack the roots came through, so roots can begin working back in over time.
How do I know the cleaning actually worked?
We record the inspection, and the camera goes back through after the cleaning so you can see the result rather than assume it. You see what the pipe looked like going in and what it looks like when we are done.
What happens if the line keeps backing up after jetting?
A line that needs the same treatment at shortening intervals is telling you something structural. The next step is a camera inspection to work out whether the problem is the pipe itself. We tell you what the camera shows and what the options are before anyone authorizes further work.
Can the price change once you are in the line?
Not without your approval. We provide written pricing and you authorize it before the cleaning begins, and nothing is added after the job without a separate written approval. Additional access work, concealed conditions, structural defects or repairs we find along the way are discussed and approved separately.
