Harris County
Plumber in Houston, TX
Houston is flat, humid and built on expansive clay, which makes it one of the toughest cities in the country on buried plumbing. Slab foundations dominate, so a leak under the floor or a broken sewer line under the house is a common call, and heavy Gulf storms test every drain.

Houston homes and their plumbing
Older neighborhoods like the Heights and Montrose have early 1900s homes with cast-iron drains, while most suburbs are post-1970 slab construction with copper or PEX supply.
Water and sewer
Houston Public Works provides water and wastewater service inside the city; many suburbs are served by municipal utility districts (MUDs).
Permits
Plumbing permits inside city limits are issued through the Houston Permitting Center; unincorporated Harris County areas follow county and utility-district rules.
Local plumbing issues in Houston
Shifting clay and slab leaks
Houston's clay swells in wet months and shrinks in drought, cracking cast-iron drains under slabs and stressing supply lines.
Hurricane and flood season
Tropical storms and heavy rain can back up sewers and flood low-lying neighborhoods; backwater valves and clear main lines matter here.
Rare hard freezes
Homes built for heat often have pipes in attics and exterior walls, so an occasional deep freeze can split lines across the city at once.
