AI receptionist for plumbers: emergency, after-hours and urgent calls

An AI receptionist for a plumbing company answers the calls you can’t get to while you’re under a sink or halfway through a repipe. Buildrok’s asks what’s happening, whether water is leaking right now and when they need someone, then emails you the job. When it’s an emergency (a burst pipe, sewage backing up, no water at all) it takes the caller’s number first, tells them it’s marking the call urgent, and your email arrives with URGENT in the subject line. It does not put urgent calls through to you automatically. If a caller asks to speak to a person and you’ve set a transfer number, it offers to put them through; otherwise it takes the message and tells them you’ll call back.

The calls that can’t wait

Water does its damage by the minute, and the people calling you know it. Triple-I’s figures, from ISO data that leaves out Texas, Alaska and Puerto Rico, show water damage and freezing made up 22.6% of homeowners insurance losses in 2023, and the average claim for that cause over 2019 to 2023 was $15,400. That’s the homeowner’s insurance bill, not your invoice. But it’s why the person standing in an inch of water calls the next plumber the moment yours rings out.

Every plumbing receptionist starts with three urgent cases:

• a burst pipe or active leak
• sewage backing up
• no water at all

You add your own to that list. A water heater dumping onto a finished floor, a restaurant with no hot water before service, a slab leak pushing water up through the tile: whatever you’d drop a job for.

Winter adds its own version of the last one. The Red Cross tells homeowners that if they turn on a faucet and only a trickle comes out, they should suspect a frozen pipe, because water expands as it freezes and can break the pipe holding it. The receptionist won’t tell a caller that’s what they’ve got. It writes down “no water since this morning, it’s 18 degrees out” and lets you decide.

What it asks a plumbing caller

It asks one question at a time, in whatever order the conversation goes. For plumbing it’s told to find out:

• what is happening, in the caller’s words
• whether water is leaking right now
• when they need someone

Then the things it gets on every call: a name, the best number to call back (read back once, so a wrong digit gets caught), the town or address, and whether it’s urgent. If a caller won’t give something, it moves on instead of asking twice. Our post on questions your AI receptionist should ask covers what’s worth asking and why.

This is a made-up call, with an invented company, caller, number and address, at 9:47 on a Tuesday night:

Receptionist: Thanks for calling Rivera Plumbing. Calls are recorded so we get your details right. How can I help?

Caller: Hi, my water heater’s leaking. There’s water all over the garage floor.

Receptionist: Sorry to hear that. Is it still leaking right now?

Caller: Yeah, slowly.

Receptionist: Okay. What’s the best number to reach you?

Caller: 512-555-0147. It’s Dan.

Receptionist: Thanks, Dan. I’m marking this as urgent for Luis. If you know where your main water valve is, you can shut it off. What’s the address?

How an urgent call actually reaches you

This is the part worth being exact about, because “it handles emergencies” can mean a lot of things. Here’s what happens, step by step:

1. Your cell rings first. Conditional call forwarding only sends the receptionist the calls you don’t answer, or miss because you’re already on another call. You keep your number and your carrier.
2. If you don’t pick up, the receptionist answers. As soon as a call sounds urgent, it gets the number before anything else, then tells the caller it’s marking the call urgent. If the line drops right after, you still have someone to call.
3. It finishes the call and you get an email with the subject “URGENT: Dan needs a callback”. The email lists Name, Phone, Address, Service, Details, Best time to call and Urgent. The same lead is in your Lead Inbox with the recording and the transcript.
4. You call back.

What it doesn’t do: it doesn’t transfer a call to you because the call is urgent, it doesn’t text you, and it doesn’t text the caller. It also never promises a time, so Dan isn’t told someone is on the way when nobody is.

The transfer only happens when the caller asks for a person. If you’ve set a transfer number, it offers to put them through, and if they agree, it does. The call reaches you showing the receptionist’s number rather than the caller’s, so save that number in your contacts under a name you’ll recognize. Leave the transfer number blank and it takes the message instead.

Since the email is how urgent calls reach you, set your phone to notify you for those emails, even when other mail is silenced. Many mail apps let you do that for a single sender.

The shut-off valve rule

For an active leak, the receptionist may suggest the caller shut off the main water valve, if they know where it is. That’s the only repair advice it gives. It won’t walk someone through finding the valve, won’t tell them to open a cleanout or drain the water heater, and won’t guess at the cause.

There’s a reason for drawing the line there. Shutting the main is the step most plumbers would tell a caller to take anyway, and it only suggests it to someone who already knows where theirs is. Anything past that is a stranger following repair instructions from your business’s number in a flooded basement, which is a conversation you’d rather have yourself. And if anyone is in danger, it tells them to hang up and call 911 first.

The gas smell rule

If a caller says they smell gas, the receptionist tells them to leave the building and call 911 or their gas company now. It doesn’t troubleshoot the water heater or the stove with them. Plenty of plumbers run gas lines and service gas water heaters, so you’ll get these calls, and the caller needs to hear “get out” before anything else.

Water heater calls and the price question

“Any idea what a new water heater runs?” comes up on a lot of water heater calls. The receptionist never gives a price, a range, a ballpark or an estimate. It says something like “I can’t give prices, but Luis will go over that with you,” and moves on. It won’t say whether the heater needs replacing, either.

You already know why. Tank or tankless, gas or electric, the venting, the expansion tank, whether there’s a permit, how hard it is to get to, haul-away: a number said on the phone becomes the number you’re held to at the door. If one of the answers you give the receptionist has a dollar figure in it, that answer is left out rather than read to a caller.

What it can answer is what you gave it: your hours as you publish them, your service area as towns, ZIP codes or a radius, your services, and up to 15 questions with your own answers. “Do you do tankless?” “Do you work on commercial buildings?” “Do you do sewer camera inspections?” If it doesn’t know, it says you’ll cover it when you call back.

After-hours callers

Forwarding has no clock. A call you don’t answer at 9:40 PM goes to the receptionist the same way a call at 2 PM does. If a caller asks, it gives your hours as published and never says whether you’re open right now, so the person with a running toilet at 11 PM gets their details taken instead of a “we’re closed” that sends them elsewhere.

That leaves the decision with you. Call the URGENT one back tonight, or first thing, or not at all if it’s outside what you do. Some plumbers charge for after-hours work and some don’t take it. The receptionist doesn’t commit you either way. We wrote more about this in after-hours calls on a job.

The next morning

Open the Lead Inbox, start with the urgent leads, and play the recording on any where the details are thin. Mark each lead contacted, quoted, booked or lost as you go, so a quote from Tuesday doesn’t go quiet. If you have a Buildrok website, the form enquiries are in the same list, labeled “Website form” beside the “Phone call” leads. You can export the lot to CSV whenever you want it in a spreadsheet.

When an answering service is the better choice

If you run true 24-hour emergency service and need every urgent call put through to an on-call tech by rule, a live answering service that dispatches is the better fit today. The receptionist doesn’t route calls by urgency. The same goes if many of your callers would rather speak Spanish, since it speaks English only, or if you regularly get several calls in the same minute, because answering several at once isn’t something we promise today. We compared the options fairly in AI receptionist vs answering service vs virtual receptionist.

If your problem is the calls you miss on a job or late in the evening, and a written lead with URGENT on it is enough for you to act on, that’s what this is built for. To put a rough number on what those calls are worth, read what a missed call costs a trade business.

Getting it on your phone

We set it up with you on a call, from your services, hours and service area, or from your Buildrok website if you have one. Before it takes a real call, it rings your cell from its own number so you can hear it. That test call makes no lead and uses no minutes. Then you dial your carrier’s forwarding code, and you can change anything or switch it off from the dashboard later. The plan includes 150 minutes of calls a month, and when they’re used up it switches to taking messages instead of charging you more until the 1st; see pricing for the rest.
