We will cover quick shut-off, temporary repairs, and the smartest path to a lasting fix. If things are urgent, our Dallas–Fort Worth team is on call 24/7.

First Steps: Make It Safe And Stop The Water

A calm, quick response protects your home and wallet. Take these steps right away:

Kill the water supply
- Turn the nearest fixture shut-off clockwise. Look under sinks or behind toilets.
- If you cannot find it, close the main shut-off at the meter box by the street or at your home’s main valve.
Cut power near the leak
- If water is near outlets or appliances, turn off the breaker for that zone.
Drain pressure
- Open a nearby cold-water faucet to relieve line pressure and slow the leak.
Contain the water
- Lay towels, set a bucket or pan, and move valuables. Snap photos for insurance.

In North Texas, many homes sit on slab foundations. A fast shut-off is vital because water can travel under flooring and wick into walls within minutes.

Identify The Pipe And Leak Type

Plastic water lines in homes are usually one of the following:

PVC: white, rigid, common outdoors and for cold water. Typically solvent-welded.
CPVC: off-white or light yellow, rated for hot and cold water indoors.
PEX: red, blue, or white flexible tubing with crimp or clamp fittings.

Leak patterns to look for:

Pin-hole spray or weeping at a joint
Drip at a threaded adapter
Crack from impact or freeze
Hidden leak signs: meter moves while fixtures are off, warm spots on slab, hissing in walls

If floors feel warm or you hear water under concrete, note that any leak in a pipe located under a home’s concrete floor or foundation is considered a slab leak. Slab leaks need professional detection and repair.

Temporary Fixes That Actually Work

These are short-term methods to slow or stop the leak until a permanent repair is made. Use them only after shutting off water and draining pressure.

Rubber and clamp method
- Wrap a piece of rubber (old hose or gasket) around a pin-hole.
- Tighten with a worm-gear clamp on each side of the hole.
Epoxy putty for plastic pipes
- Dry the area fully. Knead the epoxy until uniform.
- Press and shape over the crack, feather edges, and let cure per label.
Pipe repair tape
- Self-fusing silicone tape can seal small weeps. Stretch and wrap tightly 2 inches past each side of the leak.
Push-to-connect cap for PEX
- If a PEX line was nicked, a push-to-connect stop-end can cap it fast. Cut square with a PEX cutter and push the fitting on fully.

These are band-aids. Heat, movement, and water pressure can make a temporary seal fail. Plan a proper repair once the area is safe.

Permanent Repairs: PVC And CPVC

For rigid plastic lines, the best fix is to remove the damaged section and reconnect correctly.

Prepare the work area
- Keep water off. Drain the line from a lower faucet. Towel-dry the pipe.
Cut out the damage
- Use a ratcheting PVC cutter or fine-tooth saw. Make two square cuts at least 1 inch beyond visible damage.
Deburr and clean
- Smooth edges with a deburring tool or utility knife.
- Wipe dust away. Clean with approved cleaner.
Dry-fit a repair coupling or union
- For PVC/CPVC, measure a replacement segment and include solvent-weld couplings or a compression repair coupling.
Solvent-weld method (PVC/CPVC)
- Apply primer to the pipe and fitting socket.
- Apply solvent cement. Seat the pipe fully with a quarter turn. Hold 30 seconds.
- Repeat on the other side. Support the pipe while it sets.
Cure and test
- Follow the cement label for cure times based on temperature and pipe size.
- Pressurize slowly and check for weeps.

Pro tip: Match materials correctly. Do not glue CPVC to PVC with the wrong cement. Use CPVC-rated cement for hot water lines.

Permanent Repairs: PEX

PEX is flexible and forgiving, but fittings must be right.

Choose your system
- Crimp rings with copper and a go/no-go gauge
- Stainless clamp rings with a ratcheting tool
- Push-to-connect fittings for tight spaces and quick work
Cut and square
- Use a PEX cutter for a clean, square end.
Insert fitting and secure
- Slide ring 1/8 inch from end, insert the fitting fully, then crimp or clamp to spec.
Support and protect
- Use bend supports and sleeves through studs to prevent abrasion.

For a crack in the middle of a run, install a short repair section with two couplings. If the line is old or scuffed along its length, repiping that run may be smarter.

When The Leak Is In A Wall Or Under Concrete

Chasing a hidden leak can lead to unnecessary damage if done blind. Our team uses non-destructive technology to locate leaks before opening walls or floors. Included among these are sensitive audio equipment that can detect the sound of an underground leak and tiny waterproof video cameras that can travel through pipes allowing us to see the condition of your plumbing from within. These tools greatly minimize the need to damage floors, walls and ceilings.

In Dallas–Fort Worth, shifting clay soils and seasonal drought can stress lines under slabs. If the problem is not too extensive, we can complete a spot repair to the affected area. On the other hand, if the damage is more considerable, and the pipe in question is showing signs of age, it may be necessary to replace the entire length of the pipe.

Leak At A Fitting: Fix The Root Cause

Leaks at plastic fittings often come from these issues:

Over-tightening threaded adapters that cracks the hub
Wrong thread compound or tape on plastic threads
Misaligned piping that puts the joint in a bind
Thermal expansion on hot lines, especially at water heaters

How to correct it:

Disassemble and inspect for cracks.
Replace cracked fittings. Do not reuse stressed plastic threads.
Use thread sealant rated for plastics. Two wraps of PTFE tape plus a light pipe dope works on male threads unless the manufacturer says otherwise.
Add proper supports or expansion loops to reduce strain.

Burst Or Gushing Leak? Handle It Like An Emergency

If water is spraying, do the following immediately:

Shut the main water off at the meter or main valve.
Open a hose bib or lowest faucet to drain the line.
Call a licensed plumber who offers 24/7 emergency response.
Start drying within 24 hours to reduce mold risk. Use fans and a dehumidifier. Document damage.

Our first priority will be to stop the flow of water or waste into your home to limit the amount of damage caused. Then, we will get to work finding the source of the problem and repairing it.

Prevent The Next Leak

A few low-cost habits prevent repeat problems:

Soften or condition hard water to reduce scale that weakens plastic fittings.
Add pressure regulation if static pressure exceeds 80 psi.
Install water hammer arrestors near quick-closing valves.
Insulate and protect exposed lines from freeze.
For slab homes, avoid deep-root watering near the foundation that can shift soils. Maintain even moisture around the perimeter during dry spells.
Schedule an annual whole-home plumbing inspection. Small weeps are far cheaper to fix early.

DIY Or Call A Pro? How To Decide

DIY makes sense when:

The leak is accessible and on a visible straight run
You own the correct tools and materials
You can shut off water for the needed cure time

Call a pro when:

The leak is in a wall, ceiling, or under the slab.
You see multiple leaks or signs of aging pipe.
There is hot water involvement near the heater or recirculation loop.
You need camera inspection to confirm the source.
You want permit and code compliance for insurance.

Insurance And Documentation Tips

Photograph the leak, the shut-off, and any visible damage before and after work.
Save receipts, model numbers, and permits if applicable.
If flooring, drywall, or cabinetry were affected, file a claim promptly.
Ask your plumber to note the source of failure and the repair scope on the invoice.

Local Insight: DFW Slab Homes And Hidden Leaks

North Texas clay expands when wet and shrinks during drought. That movement can stress lines under slab foundations. Watch for these signs:

A water meter that moves when no fixtures are on
Warm spots on floors
Sound of running water in a quiet room
Cracks widening in tile or baseboards

If you suspect a hidden leak, check your water meter. If it indicates that water is still being consumed, you probably have a hidden leak. Call for professional locating so you avoid tearing up floors unnecessarily.

Why Non-Destructive Leak Detection Pays Off

Opening walls without a clear target multiplies costs. Our technology pinpoints leaks so access is minimal and precise. Sensitive audio detection can hear a pin-hole under concrete. Tiny waterproof cameras reveal pipe condition from inside. With a clear picture, we recommend the right fix:

Spot repair for isolated failures
Section replacement when pipe shows wear nearby
Full-length replacement when age or damage is widespread

This approach protects finishes, shortens job time, and often lowers the total bill.

What Homeowners Are Saying

"Their first plumber who came to inspect the water heater was able to immediately flag a possible water leak. We scheduled another appointment for the next day with another plumber who had special water leak detection equipment and they were able to confirm and locate the water leak. I was given a few different options for the repair and had the job done yesterday. I finally have hot water!"
–Erica S., Leak Detection

"They came out within 30 minutes of me calling them. Ryan McGinnis was super professional... He made quick work of the leak under the cabinet replacing dated plumbing. Would highly recommend Ryan and Baker Brothers."
–Anthony T., Under-Sink Leak Repair

"Pedro did a fantastic job of repairing the water leak in my front yard. I expected the process to take longer than it did. He was fast and efficient."
–James P., Yard Leak Repair

"Javier was professional and knowledgeable. I had a slab leak that was difficult to trace and fix - Javier was able to pinpoint the leak and provide the least invasive option for repair. Highly recommended."
–Carl B., Slab Leak Repair

Frequently Asked Questions

How do I know if my leak is PVC, CPVC, or PEX?

Check color and flexibility. PVC is white and rigid. CPVC is off-white or light yellow and handles hot water. PEX is flexible and often red, blue, or white.

Can epoxy putty be a permanent fix on plastic pipes?

No. It is a short-term seal for pin-holes or hairline cracks. Movement, heat, and pressure can break it. Plan a proper cut-out and replacement soon.

Is it safe to use push-to-connect fittings on PEX for long-term repairs?

Yes, when installed to spec and supported. They are code-accepted in many areas. In high-heat zones, consider crimp or clamp systems.

What if the leak is under my slab?

Call a pro for non-destructive locating. Rerouting lines above the slab is often faster and less invasive than breaking concrete, but each case is unique.

Will insurance cover a leaking plastic pipe?

Policies vary. Many cover sudden water damage but not the pipe itself. Document with photos and invoices, and call your carrier promptly.
