💧 WHY WE USE THIS PUMP
We use the Seaflo Series 33 12V fresh water pump in our campervan conversions for reliable, quiet water delivery to sinks and showers.
 
It’s a solid choice for small to mid-sized van water systems where consistent pressure and dependable self-priming matter more than high flow rates.
 
For most campervan setups, this pump offers a good balance of performance, durability, and noise levels.
