Terms of use
In this guide
Effective date: September 24, 2026
By using usaexpertplumbing.com you agree to these terms. If you do not agree, please do not use the site.
Information only, not professional advice
Our guides provide general information about home plumbing. They are not a substitute for an inspection or advice from a licensed plumber, electrician or gas technician who can see your specific situation. Plumbing codes, permit rules and licensing requirements vary by state and city.
Safety
Work involving gas, electricity, sewer lines or pressurized hot water can cause serious injury, property damage or death. Our guides point out steps that should be left to professionals. If you choose to do any work yourself, you do so at your own risk. If you smell gas, leave the building and call your gas utility from outside.
Costs and prices
Cost figures in our guides are national estimates based on published pricing data at the time of writing. Actual prices depend on your location, your home and the contractor. Always get written quotes.
Accuracy
We research our guides carefully and update them, but manufacturers change products and codes, and mistakes can happen. We make no warranty that the information is complete, current or error-free. If you find an error, please tell us.
Trademarks
Brand names such as Rinnai, Navien, Rheem, A. O. Smith, Bradford White, Noritz and State are trademarks of their respective owners. We are not affiliated with or endorsed by any manufacturer, and we use brand names only to identify the products our guides discuss.
