Local drainer for screen wash in adblue tank in London
Do not turn the ignition, not even to check the dashboard. For screen wash in the adblue tank anywhere in London, a drainer attends with a pump and a sealed tank, empties the fuel system and refills it. From £89 call-out, usually 1 to 3 hours on site; ring 01295 380724 for the price before you commit.
Screen wash thins the AdBlue out of its precise concentration, and the SCR system will throw a fault; the tank needs draining and flushing. Left sitting in the tank, it is a small job.

What to expect from the drainer in London
Expect a van with a pump and a sealed waste tank. The drainer drains the tank, flushes the system through, refuels with enough clean fuel to reach a forecourt, then starts the engine and lets it settle. You do not need a garage and the vehicle does not move until it is ready.
Questions worth asking before you book a drain in London
None of these are awkward questions. Any drainer worth calling will answer them before setting off.
- What is the total, not just the call-out, if it is a straight drain?
- Can you work on the forecourt, or does the car need to be moved?
- Do you take card payment at the roadside?
- Will you check the filter and pump if the engine ran?
- How long until you reach me in London?
What to do right now
- Leave the key out of the ignition and do not unlock the steering to push the car.
- If you are at the pump, tell the cashier; most forecourts will let the car stay in a bay.
- Call 01295 380724. Say what fuel went in, roughly how much, and where you are.
- Agree the price on the phone. Nobody travels until you have.
- The drainer pumps out the tank, flushes the lines and adds clean fuel.
- They start the engine, check it runs cleanly and take the old fuel away.

From the drainer's notebook
Fuel Fixer, the company behind Wrong Fuel Drain, holds a rating of 4.8 out of 5 from 2,190 reviews on Trustpilot, on a profile claimed since 2017.
Across recent reviews, the themes customers raise most often are staff who stay polite, professional and reassuring during what is a stressful situation, and how quickly a technician arrives and gets the vehicle back on the road in London.
The most common criticism is price. Some customers have felt the cost of an emergency drain was steep for a job that takes under two hours, and that is fair comment on an emergency call-out. It is why the misfuel call-out fee now starts at just £89 and why the full figure is quoted on the phone before a technician sets off — so nothing about the cost is a surprise at the roadside.
Common questions
Is the drain messy?
No. The fuel is pumped into a sealed tank on the van, and a drip tray catches anything from the connection. The area is left as it was.
Can I drive to a garage with screen wash in the adblue tank?
No. Every mile pushes the fuel further through the pump and injectors. A drainer comes to you, so there is no reason to move the car under its own power.
Will you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
I only put a little in — do I still need a drain?
In most modern diesels, yes. Even a small amount of petrol reduces the lubrication the pump depends on. A drain is cheap compared with a pump.
How quickly can a drainer reach me in London?
Usually the same day and often within a couple of hours. The operator gives you an arrival window on 01295 380724 before you agree.
Can I pay by card?
Yes. Card payment is taken on site once the job is done.
