Water in the diesel tank in Christchurch: a local drainer comes to you
Leave the engine off. With water in the diesel tank in Christchurch, 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.
What matters most is whether the fuel has moved beyond the tank. 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.

On arrival in Christchurch: what happens next
A good drainer asks three questions before touching anything: what fuel went in, how full the tank is, and whether the engine was started. The answers decide whether it is a straight drain or a drain plus a flush of the filter and pump. Either way it happens where the vehicle is parked.
Five things to ask a drainer before they set off
None of these are awkward questions. Any drainer worth calling will answer them before setting off.
- Will you dispose of the contaminated fuel, and can I have a note of it?
- Can you work on the forecourt, or does the car need to be moved?
- How long until you reach me in Christchurch?
- Do you take card payment at the roadside?
- Will you check the filter and pump if the engine ran?
What to do right now
- Don't turn the key.
- Check what went in: the receipt and the pump number tell you the fuel and the litres.
- Call 01295 380724 with those details and your location.
- Get a price that covers the whole job, then book.
- The drainer arrives, drains the tank, flushes the lines and filter if needed.
- You get clean fuel, a running engine and a note of what was removed.

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 Christchurch.
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 van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
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.
Do you work at night in Christchurch?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
How quickly can a drainer reach me in Christchurch?
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 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.
