The blocks on either side of Ball Road are largely single-family tract homes, many from the 1960s and 70s, built slab-on-grade. Inside, they commonly had copper or galvanized water lines and cast-iron drains; outside, a lateral of clay or cast iron ran to the street.
Decades later, these homes vary widely. Some have been repiped or had laterals replaced; others are entirely original. The only way to know what is under a given slab is to ask about past work and, when in doubt, look with a camera.
What is under a typical older home
| System | Common original material | Common issue |
|---|---|---|
| Water supply | Copper or galvanized steel | Leaks, corrosion; a separate system from drains |
| Branch drains under the slab | Cast iron | Scale, corrosion, repeat clogs |
| Main building drain | Cast iron | Buildup, occasional breaks |
| Sewer lateral | Clay or cast iron | Roots at joints, offsets, sags |
Signs the original drains are aging

Questions to ask a plumber

- What did the camera show about corrosion and scale?
- Is lining an option for my pipe, or would replacement be needed?
- Would any of this work need a permit from the City of Cypress?
Common questions
How do I know if my drains are original?
Past permits, receipts and a camera inspection are the best sources. Visible pipe in the garage or under sinks can also give clues.
Is galvanized pipe a drain problem?
Galvanized pipe in older homes is usually part of the water supply, which is a separate system from the drains.
Who handles permits for sewer work here?
The City of Cypress. Check with the city before major drain or lateral work.
