Plumbing is a skilled trade. But running a plumbing business requires a second skill set most plumbers never signed up for — writing estimates, answering emails, handling complaints, training helpers, and marketing to homeowners who found you through Google.
CNN Business ran a story on the nationwide plumbing shortage in 2023. The demand is real. The challenge is converting that demand into booked jobs — and handling the communication required to run the business professionally.
ChatGPT handles the business side. These 35 prompts cover everything from writing a tight quote to drafting a response to a bad review. Use them on your phone between calls.

Putting These Prompts to Work
The most effective way to use ChatGPT as a plumber is to treat it as your off-the-clock business manager. On your phone. Between jobs.
Three habits that make these prompts stick:
- Voice note your field observations, then paste the transcript into a documentation or estimate prompt. You'll stop losing upsell opportunities because you forgot to write them up.
- Use the triage scripts for real calls. Read the script in your phone browser during the first 30 seconds of a call — it sounds like experience.
- Respond to every review the same day. Paste the review into the negative review response prompt and send it within an hour. Payers and potential customers see the response more than the review.
