Réseau Tubulure on TF1: Plumbing Scams in Paris
On 18 January 2025, Réseau Tubulure took part in a report on plumbing scams in Paris for "Sept à huit", a weekly current affairs programme on the French channel TF1. Fake diagnoses, invented techniques, prices unrelated to the work and pressure to sign: here is what the report shows and how to protect yourself.

Why TF1 came to Réseau Tubulure
At the end of November 2024, the "Sept à huit" team contacted us. They were preparing an investigation into plumbing scams in Paris: fake diagnoses, outrageous prices, techniques that do not exist, psychological pressure on vulnerable customers.
They were looking for plumbers to:
- explain what the real job involves;
- help set up hidden-camera traps;
- show the difference between an honest professional and a scammer.
We said yes, because these practices destroy trust in our trade and make people believe every plumber cheats.
Three weeks of filming in December 2024
Filming took three weeks in December 2024, in several Paris flats, with hidden cameras and microphones and staged plumbing problems. The team documented three situations.
A victim of a late-night scam
Before the traps, the team met a Parisian woman cheated at 11 pm by so-called plumbers. Their method: turn up as an emergency, invent technical jargon such as a "cold weld", a technique that does not exist in plumbing, demand an immediate deposit and promise to come back the next day. They never came back. The scam relies on urgency, fear and impressive words.
The sink trap set-up that went wrong
First trap: a sink trap with a slight leak, a minor problem. The fake repairmen spotted the cameras and turned aggressive. The TF1 team had to leave the building by the back for safety reasons. It shows these networks are not just "chancers" who overcharge.
The water heater trap
Second trap, around a water heater in perfect working order. This time the cameras recorded everything:
- the fake diagnosis: "your water heater is dangerous, it must be replaced right away", although it worked fine;
- the outrageous price, unrelated to the real cost of a replacement;
- the pressure: "it's urgent, it could explode, you have to sign now", to stop the customer thinking or comparing.
The most common scams
"Everything needs replacing"
A dripping tap or a leaking flush, and you are told "they don't make that part any more" or "the riser is rotten", to replace the whole toilet or tap. Often a seal or a standard mechanism is enough. Ask to see the faulty part. A professional tries to repair before replacing.
The vague or missing quote
The tradesman starts, takes things apart, then gives the price at the end, when you can no longer say no. No work should start without an accepted quote (devis), even in an emergency at 11 pm. The quote should itemise travel, labour and parts.
The surprise surcharge
"It's Sunday, and it's a special pipe, so it'll cost triple." A night or weekend surcharge can exist, but it must be announced before the plumber travels. Be wary of "file opening fees" or "van fees" appearing on the invoice.
The fridge magnet in your letterbox
"SOS plumber" magnets left in letterboxes often lead to repairmen who are impossible to identify. Save the number of an identifiable professional before you need one.
5 warning signs
- An unrequested visit: they "happened to be in the area". Say no.
- A deposit demanded before the work for a repair call-out.
- A disaster diagnosis in two minutes: "everything needs redoing, it's dangerous".
- A price with nothing in common with what you were told on the phone or online.
- Pressure to sign immediately: "if you don't sign now, I'm leaving". Let them leave.
Good habits
- Insist on a written quote before any work.
- Check the company's SIRET number, the French business registration number (on societe.com or annuaire-entreprises.data.gouv.fr).
- Compare with typical prices. For a rough idea, see our prices.
- Never pay cash without a detailed invoice.
- Ask for the tradesman's insurance certificate.
- Prefer a local, identifiable professional with an address and reviews you can check.
Our article on plumber certifications in France covers the checks in detail.
What an honest plumber does
- Listens on the phone, asks questions and tells you what to do first to limit the damage.
- States their terms and a price range before travelling.
- On site, shows you the fault and explains what they will do.
- Writes a quote before larger jobs.
- Arrives with tidy tools and common spare parts, protects your home and cleans up before leaving.
- Gives you a detailed invoice.

Think you have been scammed?
- Do not sign an "end of works" form (bon de fin de travaux) if you are not satisfied.
- Dispute the invoice by registered letter with acknowledgement of receipt (lettre recommandée avec accusé de réception).
- Report it on SignalConso, the platform of the DGCCRF, the French consumer fraud authority.
- If you were threatened or money was extorted from you, file a complaint with the police.
FAQ
Which TF1 programme covered plumbing scams with Réseau Tubulure?
"Sept à huit", in a "Sept à huit Life" report broadcast on 18 January 2025 and available on the TF1 Info website.
How do I recognise a fake plumber?
They arrive unannounced or suspiciously fast, use jargon you cannot follow, announce a disaster, refuse to give a price before starting, ask for a deposit and push you to sign at once.
Can a plumber charge more on a Sunday?
A surcharge can apply in the evening, at night or at weekends, but it must be announced before the visit, not discovered on the invoice.
What if a plumber asks for a deposit for a repair call-out?
Refuse and ask for a written quote. For a routine repair, a professional is paid once the work is done.
