Blocked Drain or Leak Call: The Questions Worth Asking Before You Book It

A leak or blockage call is rarely what the caller first says it is. "My drain's blocked" can mean a hair-clogged shower trap or a collapsed pipe run. "There's water coming through the ceiling" can mean a weeping joint or a tank that has let go.

The first minute of the call decides whether you turn up with the right kit, whether you send the right person, and whether you quote something you can stand behind. Here are the questions that earn their place, in a sensible order.

Start with safety and urgency

Before anything else, find out whether this is happening right now.

• Is water still escaping? Active flow is a different job from a stain that appeared last week.
• Can they reach the stopcock, and can they turn it off? If not, talk them through finding it, or note that you will need to locate it on arrival.
• Is water near electrics? Water around sockets, light fittings or a consumer unit changes the urgency. Tell the caller to keep clear of anything electrical that is wet.
• Is there any smell of gas? That is not a plumbing job. Tell the caller to follow the gas emergency advice for their area and call you afterwards.
• Is sewage involved? Foul water coming back up inside a property needs a faster response and different equipment.

Pin down where and what

Vague locations cost you a wasted visit. Ask for specifics.

• Which fixture or area? Kitchen sink, upstairs toilet, outside gully, driveway.
• Is it one fixture or several? One slow sink points to a local blockage. Several fixtures gurgling or backing up usually points further down the line.
• Is it inside or outside? Manholes, gullies and shared pipework change who is responsible and what you need to bring.
• When did it start, and what changed? A sudden failure and a slow decline suggest different causes.
• What have they already tried? Chemical drain cleaners, plungers and rods all affect how you approach the job, and chemicals matter for your own safety when you open the pipe.

Establish who decides and who pays

This is the part people skip, then regret.

• Are they the owner, tenant or managing agent? A tenant may not be able to approve spend.
• Is the drain private or shared with neighbours? Responsibility can be unclear, and the caller may need to speak to someone else before work goes ahead.
• Will they be there? If not, who can give access, and are they contactable?
• Is the job going through an insurer or landlord? If so, they may need paperwork from you, so say so early.

Keep this to facts you can note down. Avoid giving opinions on who is liable; that is for the caller to sort out with the right party.

Confirm the practical details

Then the basics that stop a booking falling apart:

1. Full postcode, so you can check the job is inside your area.
2. A mobile number that will be answered on the day.
3. Parking or access constraints, such as a gated yard, a shared passage or a locked side gate.
4. A photo, if they can text or email one. A picture of the stain, the manhole or the pipe under the sink often settles half your questions.

Say what happens next

Callers in a panic remember very little. Finish by saying, in plain terms, what they should do now, when you or a colleague will arrive or ring back, and what the call-out covers. Only quote what you have already decided to quote. If the real cost depends on what you find, say that clearly rather than guessing.

Make the questions work when you can't pick up

You will not always be free to ask them. You are under a sink with the phone in the van, and the caller moves on to the next firm on the list. Voicemail rarely helps, because many callers simply won't leave a message.

One option is an AI answering service for plumbers, which takes the first call in your company's name and passes the job on by text and email. The service is only as good as the questions behind it, so write your list before you talk to any provider. Then ask how they would handle the points that matter to you:

• Does the call cover what the problem is and the caller's postcode, so the job can be checked against your area?
• Will it quote only what you have told it to quote, such as a call-out charge?
• Can genuine emergencies, like water near electrics or sewage inside a property, be passed to your on-call engineer on rules you set?
• Does a caller who hangs up before the call is answered get a follow-up?

If the answers are vague, keep looking. If they are clear, test it with a few calls of your own before it goes live.

A simple way to start

Take the questions above and cut them to the six you would never want to skip. Put them on a card by the phone, or in the notes app on the phone you carry. Whoever takes the call, you, a partner or a service, should be working from the same list. After a week, check which answers actually changed how you ran the job and trim the rest.
