Water in the AdBlue tank in Reading: a local drainer comes to you
The single most useful thing you can do now is nothing — leave the engine off. Then call 01295 380724. A drainer who works Reading drains water in the adblue tank on the spot, flushes through and refuels, typically in 1 to 3 hours, with a call-out from £89 confirmed up front.
The mechanism is simple. AdBlue is a precise mix. Extra water takes it out of specification and the exhaust treatment system logs a fault.

The drain itself, step by step in Reading
The job is quieter than people expect. Tank drained into the van, lines flushed, clean fuel added, engine started and watched for a few minutes. The waste fuel is logged and taken for licensed disposal, and you get a receipt showing what was done.
Five things to ask a drainer before they set off
You are going to pay for the job, so it is worth two minutes on the phone first. These are the questions that separate a straight quote from a surprise at the roadside.
- How long until you reach me in Reading?
- How much more if the engine has already been started?
- Will you check the filter and pump if the engine ran?
- What is the total, not just the call-out, if it is a straight drain?
- Is there an extra charge at night or at the weekend?
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.

Where drainers work in Reading
Most drains in Reading happen on the forecourt where the mistake was made. The rest are at the roadside after the car cut out, or on a drive the next morning. All three work; the vehicle does not need to be towed anywhere.
The drainers who cover Reading also work Tilehurst, Burghfield and Whitley, so a call from any of them is handled the same way.

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 Reading.
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
Can you drain a hire car or a company car?
Yes. Tell the hire company or fleet manager too; many prefer a drain on site to a recovery.
Do I need to stay with the car?
Ideally yes, so the drainer can confirm what happened and hand the keys back. If not, agree access on the phone.
Will the car need a service afterwards?
Not after a straight drain. If the engine ran on the wrong fuel, the drainer will tell you whether the filter should be changed.
Can I pay by card?
Yes. Card payment is taken on site once the job is done.
What does it cost in Reading?
The call-out starts at £89. The full price depends on the vehicle and how far the fuel got, and it is confirmed on 01295 380724 before anyone travels.
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.
