Water in the diesel tank in Keynsham, drained on the spot
Leave the engine off. With water in the diesel tank in Keynsham, the fix is a local drainer who comes to the vehicle, pumps the tank out, flushes the lines and puts clean fuel in. Call 01295 380724: the call-out starts at £89, the job usually takes 1 to 2 hours, and you hear the full price before anyone sets off.
Water is heavier than diesel, so it sits at the bottom of the tank and reaches the pump first, stripping lubrication and stopping the engine.

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 Keynsham.
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
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 you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
Do I need to move the car off the forecourt?
Only if it is blocking a pump. Push it into a bay with help and the engine off; the drainer can work there.
What happens to the fuel you take out?
It goes into a sealed tank on the drainer's van and is taken for licensed disposal and recycling. It is never tipped away.
Can I drive to a garage with water in the diesel 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.
How long does a drain take in Keynsham?
Usually 1 to 2 hours on site once the drainer arrives. Longer if the engine was started, because the filter and lines need flushing as well as the tank.
