Key facts: Burst Pipes in High Pointe
- Gray polybutylene line, used from around 1978 to 1997 in several million homes, is the first material to rule out.[1]
- One listing dates a Bradford Park at High Pointe home to 1993, within that period, but your house may differ.[2]
- Cedar Hill permit reports list residential plumbing permits for repairs and replacements.[3]
Know your pipe
Identify your pipe before it fails
Look at where lines are exposed: at the water heater, under sinks, behind the washer and in the attic. Note the color and material. Gray plastic may be polybutylene. White or cream rigid plastic may be CPVC. Flexible red, blue or white lines are probably PEX. Copper is easy to recognize. Take a photo, and ask a plumber what you're looking at.
Remember that a house might have more than one type, especially if it was partly repiped. A listing's date doesn't tell you what's in your walls, and many homes of this period have been altered. The goal is simply to find out, on your own schedule, rather than discover it at 2 a.m. with water running down the stairs.
Materials
Pipes by rough period and how they tend to fail
| Pipe | Common era | Typical failure | Your next step |
|---|---|---|---|
| Polybutylene | About 1978 to 1997 | Fittings or brittle sections | Plumber's opinion on replacing |
| Copper | Many decades | Pinholes, joints | Check for green crust at joints |
| CPVC | Later builds | Brittleness at bends | Careful handling during repairs |
| PEX | Most recent | Fittings or poor installation | Check any visible connections |
First steps
What to do when a High Pointe line lets go
- 1
Close the main
Know where it is, and check that it still turns.
- 2
Turn off the water heater
Gas or electric, follow the label.
- 3
Drain the lines
Open a low faucet and flush a toilet to take pressure off.
- 4
Check the ceiling below
In a two-storey home, water may already be over your head.
- 5
Keep clear of sagging ceilings
Move people out and turn off the circuit if you can.
- 6
Get help for both sides
A plumber fixes the line, and a restoration contractor dries the building.
Overhead lines
Attic runs and two-storey leaks
Many homes in this age range have supply lines in the attic, particularly the runs to upstairs baths. If one of those fails, the first sign could be a bulging ceiling rather than a puddle. Insulation will soak up water for some time before the drywall shows it. Have a look at any insulation that gets wet, as it usually needs to be replaced even if it dries on the surface.
Check for attic lines after any cold snap. February 2021's freeze showed that North Texas attics can get cold enough to split a line, and a split may only start leaking after a thaw.[4] The ceiling stain guide goes through how to tell a line from a roof leak or an AC drain.
Valves and hoses
The small valves that make a big difference
Stop valves under sinks and behind toilets are often original. They may not have been turned in years, and they can seize, or begin to leak when finally turned. Test them gently, one at a time, with the main accessible. Replace any that don't work. It's a small job, and it gives you a way to stop a leak without closing down the whole house.
Washer hoses deserve the same attention. Rubber hoses degrade, and a failure on an upstairs laundry can be severe. Braided hoses are a common upgrade, and some people shut the valves whenever they leave for a long trip.
- Test each stop valve
- Replace seized ones
- Upgrade rubber hoses
- Label upstairs shutoffs
Bigger questions
Is it time to think about repiping?
- You have more than one leak in a short timeRepeated failures suggest a wider problem.
- The material itself is a concernPolybutylene is the common example.
- Walls are already openDrying work may give access that won't come again.
- The water pressure is hard to controlA pressure test and regulator may help.
- A plumber can show you evidenceAsk to see failed sections and photos.
Rules and records
Permits, plumbers and insurance
Plumbing repairs go through Cedar Hill's Building Inspections system where a permit is required, and state-licensed trades must register with the city.[5] Monthly city reports show that residential plumbing permits are routine.[3] Ask your plumber to confirm what applies to your job.
For a claim, keep photographs, the failed section and the plumber's invoice. Burst pipes are generally covered according to Triple-I, though the age or type of pipe may come up, so read your policy.[6]
After the repair
After the plumber: drying the two-storey path
Once the line holds, the water it released has to be found. Follow it from the source downward: floor, cavity, ceiling, wall and lower floor. Extraction and drying in High Pointe explains that sequence for these homes. See also the burst pipe service page and the High Pointe page.
Water heater
Water heaters on the same schedule as the pipes
A water heater fails with the same result as a burst line. City permit reports list water heater replacements among residential plumbing permits, so it is routine work here.[3] Check the base for rust, and the flex lines at the top for crust. Know how to close the cold inlet, because you may need to act quickly in a garage or closet. Triple-I suggests inspecting water heater hoses yearly and replacing them about every five to seven years.[6]
Garage lines
A note on garage lines
Lines along a garage wall are worth insulating, as garages are rarely heated and they're easy to reach on a free afternoon.
Laundry
One more place to look
Check an upstairs laundry pan and its drain too, if you have one.
Questions
High Pointe burst pipe questions
How can I tell if I have polybutylene pipe?
Look for flexible gray plastic lines at the water heater, under sinks and in the attic, often stamped with PB codes. It isn't always visible everywhere, so a plumber is the best way to confirm it, and to tell you how much of the house has it.
Does polybutylene always have to be replaced?
Not necessarily immediately, but many owners choose to, given its failure history. A plumber can assess its condition and fittings. Some home insurers ask about it too, so check your policy and talk with your agent.
Why did a pipe fail in a house only 25 years old?
Fittings, water pressure and installation details can matter as much as age. A single failure doesn't always say much about the rest of the system, so ask the plumber to check the failed part and test the pressure.
How do I know whether a ceiling is safe after a leak above?
Treat any sag, bulge or soft patch as unsafe, and stay out from under it. A contractor can check moisture and open the section carefully, and it's worth turning off the room's light circuit until someone has checked.
