Plumbing in Houston: what locals should know
Water quality
The water in Houston is on the harder side. You may notice mineral spots on fixtures. For water heaters, this means flushing the tank annually is essential to prevent sediment buildup.
Freeze risk
Freezing is uncommon in Houston, but the risk isn't zero. During rare cold snaps, homes here are actually MORE vulnerable because plumbing isn't typically winterized. Keep pipe insulation on hand for outdoor runs.
Material recommendation
For Houston's hard water, PEX piping is ideal — it doesn't corrode or develop pinhole leaks like copper can in mineral-rich water. It's also the most cost-effective option for whole-house repiping.
Local tip
Many Houston homes built in the 1970s-80s have polybutylene (gray plastic) water pipes, which are prone to unexpected failures. If your home has them, most plumbers recommend proactive repiping before a catastrophic leak.

What pitfalls should I watch for hiring a plumber in Houston's HOA neighborhoods?
Be cautious of plumbing work contractors in Houston who pressure you to sign same-day. Legitimate contractors expect you to get competing bids and will hold their price for 30 days. High-pressure sales tactics correlate with inflated pricing. Any Houston contractor who asks for more than 30% upfront before materials are ordered is a red flag. Standard practice is 10-15% deposit, materials-on-delivery payment, and final payment on completion. In fast-growing Houston, some contractors take on more work than they can handle. Ask about their current project count — a reputable plumbing work contractor runs 2-4 jobs simultaneously, not 10-15.
