Water Slab Leak Repair

The vast majority of homes north of Dallas that were built between the 1960s and 2010s have copper water lines under the slab foundations. Copper makes an excellent water line, but over time pin-hole leaks have the tendency to develop. This can be caused by improper installation, the water line touching concrete or a piece of ferrous metal, or turbulence in the water line.

1. Symptoms

Signs of a water line slab leak may include:

A hot or warm spot on the floor
Wet spots on the floor
Cracks in the flooring
Sounds of running water
Abnormally low water pressure
A sudden increase in your water bill

3. Detecting

In order for the test to be successfully performed, there must not be any leaky faucets or toilets and the house line must be successfully isolated from the yard line. After a leak has been confirmed, Legacy Plumbing uses top-of-the-line water leak detection equipment, such as acoustic listening devices and electronic line locators to locate the leak and determine the severity of any damage.

2. Testing

For water leaks, Legacy Plumbing typically starts by confirming a leak by pressure testing the lines. A pressure gauge is typically connected to a faucet and the water is turned off at the meter or at the shut off valve in the yard. The pressure on the gauge is monitored to determine if there is a loss of pressure.

4. Repair

Water line slab leak repairs can be made through small slab penetrations or by tunneling under the perimeter. In some cases, re-routing waterlines is a more economical solution, especially when the overall pipe system is corroded. When applicable, re-routing waterlines can also be used to prevent damage to expensive flooring. Read our blog article on the Four Ways to Fix a Slab Leak for more information.

Sewer Line Slab Leak

Unfortunately, the soil in the Dallas Metro is notorious for causing slab foundations to shift over time. This ends up causing many of the sewer slab leaks in our area. Older homes may still have cast iron sewer lines, while newer homes utilize PVC piping under the slab. Cast iron can become corroded over time, while PVC piping is more likely to break. Sewer-line slab leaks can happen to older homes and newer homes. Detecting a slab leak is the first critical step, once confirmed a repair is necessary to prevent further damage.

Locating

For sewer and drain leaks, Legacy Plumbing uses isolation test balloons and sewer line camera equipment to locate the area(s) of the leak. A test ball is placed in the main sewer line at an exterior cleanout. The lines are then filled with water and monitored at the floor level to determine if the water drops. If the water does drop, a leak is confirmed. Isolation testing and running a camera in the line are the next steps to determine the exact location of the leak(s).

Repairing

After our findings, we will consult with the homeowner on the best course of action to get the leak repaired. There are many factors to evaluate and determine the best way to repair a slab leak or replace a water or sewer line. The overall plumbing layout, house layout, slope, length, and depth of the lines can all determine the best outcome. Legacy Plumbing has extensive experience in both water line and sewer line slab leaks. We will walk you through the best solution before incurring any additional costs.

If you suspect you have a slab leak, you can trust Legacy Plumbing to get it resolved accurately, completely, and efficiently.

Reviews of Slab Leak Services

Our experience with these guys was very positive! We had a hot water leak under our home’s slab, which was rather stressful. Wayne took the time to explain everything in-depth, discussed all the options and the pricing. He was extremely knowledgeable, professional, informative, and honest. We were very happy with the pricing, and the amount of time it took to complete the project successfully. The apprentice, Schuyler, was also very professional and helpful! I would definitely go to these guys for any future repairs, and would highly recommend them to all my friends and family! It’s great to have found such honest, hardworking, and knowledgeable folks that can be relied on for home repairs. Thank you, guys!

I just used Legacy Plumbing last week for a slab leak. They were knowledgeable thorough, honest, explained everything and their quote was right on. They were extremely neat and cleaned up before they left. I don’t know what their prices are for basic plumbing, but I won’t go anywhere else for big jobs.

In the last couple of years, my 43-year-old home has begun to show its age, and several of the symptoms have been in the plumbing. Luckily I found Legacy Plumbing. They have repaired cast iron pipe breaks, slab leaks, replaced my water heater, and solved additional problems. Master plumber, Wayne, has led the repair of most of these problems. He is thoroughly professional, quickly diagnoses the problem, finds leaks with amazing accuracy, completes the repair, and leaves everything cleaned up. He does all this while teaching one of the less experienced plumbers in every step of the repair, not just with what steps he is taking, but why each step is important. They are lucky to have such a mentor, and I am lucky that I found Legacy Plumbing and Wayne.

Enoch just serviced our home. He could not be any better if he tried. He even stopped by one night on his way home just to see if everything was alright. When he was here, he discovered we had a leak in our main feed line to our home while he was fixing something else. Highly efficient, friendly, and knowledgeable. Very satisfied with the service.

Yesterday we heard an unusual sound in the wall that sounded like water running, so we feared there was a slab leak. We contacted Legacy Plumbing when our son and daughter-in-law referred us to Legacy Plumbing, the company that installed a new water heater for them in the summer of this year, 2019. They had great service then, so we checked Legacy’s website and read customer reviews. That sealed it for us, and the owner, Theron Young, got on the phone to speak to me and explained the possible issue we might be having. He explained fully the job estimates and came across as very professional. His taking the time to explain things helped very much. So the appointment was made for the following day, and we were extremely pleased with Matthew and his apprentice Steven who were real professionals. The company has obviously taught its employees to be courteous, helpful, on-time, and well-trained to answer any questions we had. We trusted these men immediately and were greatly relieved when they quickly discovered that we merely had a leak in an outdoor faucet. Matthew then gave us a definite estimate of the job he and Steven had to accomplish to repair the leak by replacing the part of the faucet exposed to the outdoor. He had to cut through mortar and possibly remove a stone in the wainscotting but did a super job of repairing the hole so neatly. Very impressed! These gentlemen were so pleasant and communicated very effectively. We highly recommend this company and will not hesitate to request the team of Matthew and Steven in the future. They should have bright futures with Legacy Plumbing! Thank you, guys, for a job well done! We should be able to give you both and your company more than 5 stars!
