Why You Need a Plumbing Test After Foundation Repair in Arlington

Foundation repair is common in Arlington because of expansive clay soil. When a crew lifts or levels a slab, the water and sewer pipes under it move too, and joints can crack or separate. A plumbing test after foundation repair checks the water lines and drain lines for new leaks, so problems are found while they are small. Call (817) 285-5426 to schedule one.

Can foundation repair damage plumbing?

Yes, it can. Raising a slab even an inch or two changes the angle of the pipes underneath. Supply lines can crack at fittings, and cast iron or PVC drain lines can pull apart at joints or lose their slope. The damage may not show for weeks, while water quietly soaks the soil under the home.

Many Arlington homes built from the 1960s to the 1990s have cast iron drains and copper supply lines that are already decades old. Older pipe is less forgiving when the slab moves. Read about slab leak signs to know what to watch for.

What does a post-foundation plumbing test check?

A complete test usually has two parts. A static pressure test checks the water supply lines for leaks. A hydrostatic test checks the drain and sewer lines under the slab by filling them with water and watching the level. A sewer camera can then show where a drain line cracked or separated.

Should I test before or after foundation repair?

Both is best. A test before the work shows the condition of your plumbing, so you know what was already there. A test after the work shows whether lifting the slab caused new leaks. Many foundation companies recommend a hydrostatic test, and some warranties ask for one, so check your paperwork.

1. Get a plumbing test before foundation work starts.
2. Keep the written report and any camera video.
3. Have the foundation repaired.
4. Test again, ideally within a few weeks of the work.
5. Compare the results and share them with your foundation company if needed.

What are the signs of a plumbing leak after foundation work?

Watch for a higher water bill, the sound of running water, warm or damp spots on the floor, slow drains or gurgling in several fixtures, a sewer smell, and new cracks after the first few weeks. If the slab keeps moving after it was leveled, a hidden leak under the home may be the cause.

• Water meter moves with all taps off
• Slow drains or gurgling toilets
• Sewer smell indoors or near the slab
• Damp carpet near exterior walls
• New cracks after the foundation was leveled
