A drainer's view of Constantine
The first question from the drainer is always whether the engine ran. In Constantine, as elsewhere, most callers have not started it, and those jobs are over in about an hour.
When a drainer arrives in Constantine
First they confirm what went in and how much, and whether the engine ran — that decides how far they need to go. Then the tank is emptied into a sealed container, the fuel lines and filter are flushed where needed, clean fuel is added and the vehicle is started and checked before they sign it off.
Five things to ask a drainer before they set off
A drainer should be happy to answer all of these on the phone. If they will not give a price before travelling, ring someone else.
- Can you work on the forecourt, or does the car need to be moved?
- Do you take card payment at the roadside?
- Is the vehicle over 3.5 tonnes, and does that change the price?
- How much more if the engine has already been started?
- Will you dispose of the contaminated fuel, and can I have a note of it?
What drainers deal with in Constantine
What to do right now
- Leave the ignition alone — on many cars even unlocking it powers the fuel pump.
- Push the car clear of the pump if needed, with someone steering and the engine off.
- Call 01295 380724 and give the fuel, the amount and your exact location.
- Ask for the whole price, not just the call-out, and agree it.
- The drainer drains the tank into a sealed container and flushes the lines.
- Fresh fuel goes in, the engine is started and the waste fuel leaves with the drainer.

Where you can be drained in Constantine
Across Constantine, Cornwall the common locations are the filling station itself, a lay-by a mile or two down the road, and home. If you are on a motorway hard shoulder, call the emergency services first; the drainer can meet you once the vehicle is somewhere safe.
Coverage takes in postcode district TR11 in Cornwall. If you are just outside, call anyway — the drainer covering the next area will usually come.
The drainers who cover Constantine also work Falmouth, Mylor Bridge, Flushing and Mawnan Smith, 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 Constantine.
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
How long does a drain take in Constantine?
Usually 45 to 90 minutes on site once the drainer arrives. Longer if the engine was started, because the filter and lines need flushing as well as the tank.
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.
Do you cover all of Constantine?
Yes — forecourts, roadsides, homes and workplaces across Constantine and the surrounding area.
Does insurance cover petrol in a diesel car?
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.
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
