The whole house
All the supply pipe, from where it leaves the meter connection to every tap, comes out and new pipe goes in through small cuts in drywall that are patched once the work is done.
Rusty water from the hot tap, pressure that drops when a second fixture runs, or pinhole leaks turning up in one pipe after another are signs that the supply piping is wearing out. Repiping replaces it, all at once or one run at a time.
The sections below cover the ways to repipe, what Garland’s service line map shows and where permits come in.

All the supply pipe, from where it leaves the meter connection to every tap, comes out and new pipe goes in through small cuts in drywall that are patched once the work is done.
When only one bathroom, the kitchen or the hot line to the heater is giving trouble, that single run is swapped and the remaining pipe stays in use.
The buried line from the water meter into the house belongs to the property owner, while the city owns the line from the main up to the meter. A leaking or undersized owner’s line is replaced from the meter to the house.
Flexible PEX snakes through walls with few joints, while copper goes in as straight rigid pieces soldered at every bend. Which one fits depends on the house and the route, and the plumber explains both.
Garland Water Utilities keeps an online Service Line Inventory Map with the recorded material of each service line. Addresses with a galvanized line show a yellow marker and those with an unknown line a grey one, and both were sent a Notice of Service Line Material letter.
Unknown means the material has not been confirmed yet; it does not mean the line is lead. The city says it has encountered few lead service lines over the years and replaced any lead it found, and homes built before the 1988 lead ban are being inspected first.
Garland’s permit pages do not name whole-house repiping on its own. It counts as plumbing systems and repairs, which the city lists among projects that may need a permit, and pipe repairs under a slab come under the separate Under-Slab Repairs permit.
State law makes a permit the rule for plumbing work in Texas cities above 5,000 people, and new supply piping is not among its short list of exceptions. The Responsible Master Plumber on the job obtains the permits and requests the inspections.
A leak in one spot may only need leak detection, and the water heater page covers the tank at the end of the hot line. The rest of our services are on the homepage.
