The Questions

- Can you send a certificate of insurance naming us as additional insured?
- Are you licensed in this state, and may we have the license number?
- Do you have certified backflow testers, and do you file reports with the water utility?
- Do you offer 24-hour emergency service, and what is the call-out fee?
- Do you camera-inspect drains before recommending replacement?
- Is the quote flat-rate or time and materials?
- What warranty do you give on labor and parts?

Tips From Common Practice
- Label every main and zone water shutoff before you need them.
- Your water utility usually sets the backflow test deadline; keep its notice on file.
How Often to Schedule
Facilities usually schedule plumbers yearly for backflow tests and water heaters, plus repairs as needed. Your lease, insurer, local code and equipment manuals can require more, so check them first and add the dates to your preventive maintenance schedule.
Then line up offers in the quote comparison tool, and see how to verify a license and insurance.
