AI prompts for plumbers
Free, copy-paste prompts you can use today — under the house, in the ute, or at the kitchen table doing paperwork.
Short version: Plumbers use AI as a fast writing and thinking mate. You paste a prompt, swap the bits in [square brackets] for your job details, and it drafts the quote wording, the text to the customer, the follow-up, the review request or the supplier email — in seconds. You still check it and send it. It doesn’t replace your trade or your licence; it clears the paperwork so you can get back on the tools.
How to use this page: pick a prompt below, copy it into ChatGPT, Copilot, Gemini or Claude, replace every [bracketed] bit with your real details, then read it before you send. The AI never signs off gas or compliance — that’s your licence, your responsibility.
1. Quoting & variations
Quotes win or lose work on how clear they read. These get the wording tidy and professional without you staring at a blank screen after a day under houses.
Act as an experienced licensed plumber writing a customer quote. Turn my rough notes into a clear, professional quote in plain English. Customer: [customer name]. Job address: [job address]. Scope in my words: [scope, e.g. supply and install new 250L gas hot-water unit, remove old unit, replace tempering valve and isolation cocks]. List the work as clear line items, add a short friendly intro and a "what's included / not included" section. Keep the pricing blank for me to fill in. Australian spelling.
Write a short, polite message to [customer name] explaining a variation to their job at [job address]. Original scope: [original scope, e.g. swap the kitchen mixer]. Change now needed: [what changed and why, e.g. isolation stops under the sink are seized and corroded, need replacing before I can fit the new mixer]. Explain in plain terms why it's needed, that it adds [extra cost/time], and ask them to approve before I proceed. Friendly but clear. No jargon.
I'm quoting a [job type, e.g. full re-pipe of a 3-bed house in PEX] for [customer name] at [job address]. Scope: [scope]. Break this into logical stages a customer can understand (e.g. rough-in, changeover, fit-off and testing), and suggest a fair progress-payment schedule for each stage (deposit, then stage payments, then completion). Explain what happens at each stage in one line. Leave dollar amounts blank for me.
Write 3 short options for a friendly closing paragraph on a plumbing quote. My business: [business name], a licensed plumber in [area]. What we're good at: [e.g. tidy work, on time, licensed and insured, compliance certificate supplied, clean up after ourselves]. Keep each option to 2-3 sentences, confident but not salesy. Australian tone.
Act as a senior licensed plumber reviewing a job scope before I quote it. Job: [job type, e.g. bathroom rough-in] at [job address]. My current scope: [paste your scope / line items]. List anything commonly forgotten on this type of job (materials, prep, access under the house, water isolation, disposal of old fittings, making good, tempering valve, backflow, compliance certificate). Just a checklist of "did you allow for..." questions. Don't invent prices, and don't make compliance calls for me.
Great for catching the stuff that eats your margin later.
2. Customer comms
Half the complaints plumbers cop are about communication, not the work. These keep customers in the loop with almost no effort.
Write a friendly, professional reply to a new job enquiry. Customer wrote: "[paste their message, e.g. hot water's gone cold and there's water pooling near the unit]". I'm a licensed plumber in [area]. Thank them, confirm I can help, ask the 3-4 questions I need to quote or triage it ([e.g. address, photos of the unit and its data plate, is it gas or electric, is water still leaking now]), and say I'll get back to them. Keep it short and easy to read on a phone.
Write a short, apologetic text to [customer name] letting them know I'm running about [X minutes/hours] late to their job at [job address] because [reason, keep it honest, e.g. a burst-pipe emergency ran over]. Give them a new arrival time and thank them for their patience. Warm and genuine, not corporate.
Help me write a calm, honest message to [customer name] about a problem on their job at [job address]. The issue: [what went wrong / what I found, e.g. the drain's blocked by tree roots in the main line, not just a simple clog]. What I recommend: [your fix / next step, e.g. CCTV the line then cut the roots and quote a repair]. Acknowledge it, don't over-apologise, explain the options clearly, and reassure them I'll sort it. Keep it steady and professional.
Explain [technical issue, e.g. why an old hot-water unit needs a tempering valve fitted on changeover / why the blocked drain keeps coming back without a proper root cut] to a customer who isn't a plumber. Use a simple everyday comparison, keep it to a short paragraph, and end with what it means for them (cost/time/safety) without scaring them. Plain, friendly Australian English.
A customer says my quote for [job, e.g. the hot-water changeover] is more than they expected. Help me write a polite, confident reply. My quote covers: [key inclusions and quality points, e.g. quality unit, licensed work, tempering valve, removal of old unit, compliance certificate, warranty]. Don't be defensive or drop the price. Reinforce the value, offer to walk them through the quote, and leave the door open. Short and respectful.
3. Scheduling & follow-ups
The jobs that go cold are usually the ones nobody followed up. Let AI write the nudge so you actually send it.
Write a friendly follow-up message to [customer name] about the quote I sent for [job, e.g. the bathroom re-pipe] at [job address] on [date]. Check if they've had a chance to look at it, offer to answer any questions, and keep it low-pressure. 2-3 sentences, sounds like a real person, not a chase-up bot.
Write a short confirmation text for [customer name] for their job at [job address] tomorrow. Include: arrival window [time], roughly how long I'll be there, anything they need to do first ([e.g. clear access to the hot-water unit, keep pets inside, know that water will be off for about an hour]), and my number to call if anything changes. Clear and friendly.
Write a message to [customer name] to book the next stage of their job at [job address]. Last stage done: [what was completed, e.g. rough-in passed]. Next stage: [what's next, e.g. fit-off and testing] which takes about [duration]. Offer [2-3 date options] and ask which suits. Friendly and easy to reply to.
Help me reschedule [customer name]'s job at [job address] from [original date] because [honest reason, e.g. an emergency burst pipe callout]. Apologise briefly, offer [2 alternative dates], and reassure them their job is still a priority. Keep it warm and short.
Here are the jobs I've got on this week: [list jobs with rough location and duration, e.g. Mon - Smith hot-water changeover (half day, Newtown); Tue - Jones blocked drain / drain snake (2hr, Marrickville); Wed - Lee bathroom rough-in (full day, Ashfield)...]. Suggest a sensible order to run them to cut down driving between suburbs, and flag anything that looks too tight to fit. Keep it as a simple day-by-day list.
4. Chasing reviews
Reviews are how new customers decide to call you. Most happy customers just forget to leave one — a good ask fixes that.
Write a short, warm message asking [customer name] for a Google review now their job at [job address] is finished. Thank them, say it genuinely helps a small local plumbing business, and make it easy: mention I'll send the review link. Keep it humble and no-pressure. 2-3 sentences.
Send it the day after you finish, while they're still stoked with the hot water working again.
Write a genuine, friendly reply to this 5-star review for my plumbing business: "[paste review]". Thank them by name if given, mention something specific from their job (e.g. the hot-water changeover or the leak repair), and keep it warm and human. Don't sound copy-pasted.
Help me reply to a negative review for my plumbing business. The review says: "[paste review]". My side / what actually happened: [your notes]. Write a calm, professional public reply: acknowledge their experience, don't get defensive or argue details publicly, and invite them to contact me directly to sort it. Short and level-headed.
Write a casual message I can send to past happy customers asking them to keep me in mind for friends and family who need a plumber. Friendly, not pushy, no discount gimmicks. Sounds like a local plumber who does good work and appreciates word of mouth.
5. Supplier & admin
The boring paperwork that piles up on the passenger seat. Knock it over in a couple of minutes.
Write a polite but firm email to [supplier name] chasing an order. Order: [what you ordered, e.g. 250L gas hot-water unit and tempering valve] placed on [date], order ref [number]. It was due [date] and I've got a customer changeover booked that depends on it. Ask for a firm delivery date and to be called if there's a delay. Professional and to the point.
Write a short email to [supplier name] requesting a price and availability on the following for a job: [paste your materials list, e.g. PEX pipe and fittings, isolation cocks, tempering valve, flexi hoses]. Ask for trade pricing, lead time, and whether they can deliver to [job address / suburb]. Keep it brief and businesslike.
I'll list what I spent on a job and I want a tidy cost summary. Job: [job / customer]. Costs: [list each item and amount, e.g. hot-water unit $1180, tempering valve $95, copper and fittings $140, skip/old-unit disposal $60, apprentice half day $220]. Group them (materials / labour / hire / disposal), total each group and the whole job, and format it so I can drop it straight into my records.
Don't paste anything you wouldn't want stored — keep customer bank details and the like out of it.
Draft a starting-point Safe Work Method Statement for [task, e.g. working in a confined subfloor replacing corroded drainage pipe]. List the main hazards, the controls I should have in place, and PPE required, as a simple checklist. Note that I need to review it against my site's actual conditions and local regulations before using it. Don't treat it as final or compliant on its own — gas and compliance sign-off stays with my licence.
Always have a qualified person check safety and compliance documents against current regs and the actual site.
Write a short, friendly email to send with an invoice to [customer name] for their completed job at [job address]. Thank them, note the invoice is attached, state the total [$amount] and due date [date], mention the compliance certificate is included where relevant, and how they can pay [payment methods]. Warm and professional. Australian tone.
Write a polite reminder to [customer name] about an overdue invoice for their job at [job address]. Invoice [number], amount [$amount], was due [date]. Assume it's an honest oversight, keep it friendly, restate how to pay, and ask them to let me know if there's any issue. Firm but respectful.
Want this to just… happen, without the copy-paste?
Prompts are a great start. The real win is when the phone gets answered on the burst-pipe call, the quote drafts itself from your voice notes, the invoice chases itself and the review request goes out — automatically, wired into your email, calendar and jobs.
