Missed call text back for plumbers: the Sunday night call, answered.

Plumbing emergencies do not keep business hours. Burst pipes, blocked drains and hot water failures cluster into evenings, early mornings and weekends, which is exactly when nobody is sitting by a phone.

The pattern is specific to the trade. An accountant's phone rings on Tuesday morning. A plumber's rings when somebody walks into a flooded laundry, and that happens whenever it happens.

During the day the problem is different but the result is the same. You are under a house, in a roof cavity or holding something that will spill if you let go, and the phone is in the ute.

So the calls that go unanswered are not the quiet ones. They are the urgent ones, from somebody with water where it should not be, who will pay whatever it takes to make it stop tonight.

Almost nobody leaves a plumber a voicemail. A person with water coming through a ceiling hangs up and rings the next number, so the call leaves no record anywhere you would look.

That invisibility is the reason this goes unfixed for years. A missed call that leaves a message is an annoyance you deal with in the morning. A missed call that rings out is not an event at all, and it does not appear in any figure you review.

It also means the loss is systematically underestimated. Ask most plumbers how many calls they miss in a week and the answer is a shrug, because there has never been a number attached to it.

What makes it worse for plumbers than for most trades

• The customer is in a hurry by definition.

  Nobody rings a plumber to browse. They ring because something is wrong now, and they keep dialling until somebody picks up.

• The urgent jobs pay best.

  An after-hours call-out carries a premium before any actual work is quoted.

• There is no receptionist.

  On most plumbing businesses the person who answers the phone is the person holding the tools.

An emergency call-out is worth several hundred dollars before anything is quoted, and the customer who does not reach you rings somebody else within about a minute.

The arithmetic gets decided quickly at that point. Recovering one call-out a month more than covers a text-back, and most plumbing businesses missing calls are missing considerably more than one.

The larger loss is the one after it. A blocked drain becomes a repair, the repair becomes a hot water replacement two years later, and the customer who found somebody else that night takes all of it with them.

There is a version of this where the number really is close to zero, and it is a plumber with somebody reliably on the phone. If that is you, none of the rest applies.

When a call to your number goes unanswered, a text goes out within seconds in your own words, saying you are on a job and asking what they need. They reply in writing and you deal with it when your hands are free.

The reason it works is that a reply in seconds stops somebody dialling the next plumber. It is not the quality of the message that does that, it is the speed, and speed is the one thing a person on a job cannot offer.

It is not pretending to be you. It says the business is busy, which is true, and it asks enough that when you do ring back you already know the address and what is wrong.

What it does not do

• It does not answer the phone.

  A customer who wants to talk to a plumber right now still cannot, and for a genuine emergency that sometimes matters.

• It cannot text a landline.

  Those calls alert you directly instead, so the enquiry is not lost, it just comes to you rather than to them.

• It does not do the ringing back.

  It holds the job. Winning it is still yours.
