Water in the screen wash tank in Wembley: a local drainer comes to you
Do not turn the ignition, not even to check the dashboard. For water in the screen wash tank anywhere in Wembley, a drainer attends with a pump and a sealed tank, empties the fuel system and refills it. From £89 call-out, usually 45 to 90 minutes on site; ring 01295 380724 for the price before you commit.
The mechanism is simple. Plain water in the washer bottle freezes in winter and can crack the bottle, the pump or the lines; it is drained and refilled with proper fluid.

On arrival in Wembley: 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.
- How long until you reach me in Wembley?
- Do you take card payment at the roadside?
- Will you check the filter and pump if the engine ran?
- Is there an extra charge at night or at the weekend?
- Is the vehicle over 3.5 tonnes, and does that change the price?
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 Wembley.
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.
Does insurance cover water in the screen wash tank?
Many policies exclude misfuelling. Some breakdown cover and optional add-ons include it. Check your policy wording before assuming either way.
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.
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.
Do you work at night in Wembley?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
