Plumbing in Dallas Homes

Dallas has houses from almost every decade, and the older the house, the more its plumbing has been patched over the years. In a house from before the 1970s, it's common to find galvanized steel water lines that have narrowed inside, or cast-iron drain lines under the slab. Either one can show up as low water pressure, slow drains or a leak. Most Dallas homes also sit on the same shifting clay as the rest of North Texas, which is hard on slabs and the pipes beneath them.

Dallas homes get their water from Dallas Water Utilities, which draws on six reservoirs, including Lewisville Lake, Lake Ray Hubbard and Lake Tawakoni.

"Mario and his helper arrived on time, asked what was needed and prepared a quote. They then proceeded to replace stems in three sets of faucets and rebuild a toilet. They were friendly, efficient and most knowledgeable. When they needed to go to the supply store for older parts, they returned quickly."

"I now know who will replace our water heater, which is aging, and I have found my plumber. Thank you Mario."

Frequently Asked Questions

Do you charge extra to come into Dallas?

No. There's no trip charge anywhere in our service area. We don't generally schedule work outside it.

My water pressure keeps dropping. Could it be old pipes?

It could. Older galvanized water lines narrow inside as they corrode, and a hidden leak can lower pressure too. We'll find the cause before suggesting a fix. Our post on low water pressure covers the usual suspects.

Where does Dallas get its water?

Dallas Water Utilities supplies the city from six reservoirs, including Lewisville Lake, Lake Ray Hubbard and Lake Tawakoni.
