Water in petrol tank in St Austell? Drained where it stands
Before anything else, keep the key out of the ignition. A drainer covering St Austell can be with you the same day for water in the petrol tank, drain it where the car stands and have you moving in about 1 to 2 hours. The misfuel call-out is £89 and the total is quoted on 01295 380724 before they travel.
The mechanism is simple. Water in petrol gives misfires, stalling and non-starts; the tank is drained, the lines flushed and fresh fuel added.

What the drainer does when they reach you in St Austell
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.
What to ask on the phone before a drainer travels to St Austell
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.
- Is there an extra charge at night or at the weekend?
- 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?
- Will you dispose of the contaminated fuel, and can I have a note of it?
What to do right now
- Don't press the start button or turn the key.
- Take a photo of the pump display: it shows the fuel type and the litres.
- Ring 01295 380724 and describe where the car is.
- Agree the price before booking — the call-out starts at £89.
- The drainer empties the tank and flushes the system where the car stands.
- They refuel, start the engine and check it before handing back the keys.

Forecourt, roadside or drive: where we drain in St Austell
Most drains in St Austell 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 St Austell also work Trewoon, Charlestown and Carlyon Bay, 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 St Austell.
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
Will my engine be damaged?
Not if it has not been started. The wrong fuel sitting in the tank touches nothing that a drain cannot clear. Damage starts once it circulates.
How long does a drain take in St Austell?
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.
Can I drive to a garage with water in the petrol 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.
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.
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.
Does insurance cover water in the petrol tank?
Many policies exclude misfuelling. Some breakdown cover and optional add-ons include it. Check your policy wording before assuming either way.
