Texas-specific toilet issues in Katy
Katy's hard water can shorten fill valve life to about 5 years versus 10 in soft-water areas. Low water pressure in some Katy neighborhoods may cause weak flushes—check your pressure first. Pre-1980 homes in Katy might have non-standard rough-in distances (10" or 14") instead of the common 12". Measure before buying a new toilet. These Texas-specific factors affect repair and replacement choices.

Toilet Repair FAQs – Katy, Texas
- Should I repair or replace my toilet in Katy?

- Is a smart toilet worth it in Katy?
- Smart toilets ($700-2,200) offer heated seats, bidet, and self-cleaning. In Katy's humid climate, they can be comfortable. Payback is mainly from water savings, but upfront cost is high.
- How long should a toilet last in Katy?
- A typical toilet lasts 20-30 years. Hard water in Katy may shorten fill valve life to 5 years, but the porcelain itself holds up. Replace when cracks appear or flush performance drops.
- Can I replace the wax ring myself?
