Detailed Reviews
1. Shurflo 4008 Water Pump — £39.99
Rating: 4.7/5
The Shurflo 4008 is the industry standard for 12V water pumps. At £39.99, it delivers 3GPM at 40psi, enough pressure for a proper shower experience. It is quiet, reliable and has been the default choice in motorhomes for decades.
2. Dometic Electric Water Pump — £54.99
Rating: 4.5/5
The Dometic pump is the premium alternative to Shurflo. It is slightly more expensive but the build quality is exceptional and the integrated pressure switch means it turns on and off automatically when you open the tap.
3. Flojet 28 Series Water Pump — £44.99
Rating: 4.4/5
The Flojet 28 Series offers Shurflo performance at a lower price point. It is quieter than expected and the brass fittings are a step up from plastic alternatives.
4. Rule 12V Self-Priming Pump — £69.99
Rating: 4.3/5
Rule's marine-grade pump is the most durable option. Self-priming means it can suck water from a tank below the pump, useful in deep van floor boxes. At £69.99, it is the most expensive but built to last 20+ years.
5. G Interpret 12V Diaphragm Pump — £24.99
Rating: 4.2/5
The G interpret diaphragm pump is the budget option at £24.99. It is not as quiet as the Shurflo but delivers adequate pressure for a standard sink. Perfect for budget builds.
Buying Guide: What to Look For
Key factors when choosing a campervan water pump:
-
Pressure — 3-4 bar (40-60 psi) is the sweet spot for UK shower pressure. Too low and the shower is tepid; too high and you will spray water everywhere.
-
Flow rate — 3GPM (gallons per minute) is standard. This delivers a comfortable shower without wasting water.
-
Noise — The Shurflo 4008 runs at under 50dB, quiet enough to hear music playing. Louder pumps are fine for daytime use.
-
Self-priming — A self-priming pump can suck water from a tank below the pump. Essential for deep floor boxes in van builds.
FAQ
What pressure do I need for a campervan shower?
You need 3-4 bar (40-60 psi) for a comfortable UK shower experience. The Shurflo 4008 delivers 3GPM at 40psi, which is the sweet spot. Too little pressure and the shower is tepid; too much and you will spray water everywhere when turning on and off.
How much water do I need for a 5-day UK camping trip?
A typical UK van lifer uses 10-15 litres per day (drinking, cooking, basic washing). For 5 days, carry 80-100 litres. The Shurflo 4008 pump delivers water at 3GPM, enough for a comfortable shower in 5-7 minutes.
Conclusion
The Shurflo 4008 at £39.99 is the industry standard for campervan water pumps. It delivers reliable pressure, runs quietly, and is widely available in the UK. For budget builds, the G Interpret Diaphragm Pump at £24.99 is a proven alternative.
