Finding 12v Water Pump Supplies

If you’ve already decided you need a 12v water pump or maybe several for your low voltage plumbing project you might be wondering where is the best place to get one. Unfortunately there is no single correct answer because of the considerable effect that location has on availability. You might live near an electrical wholesalers for example, but after making enquiries they just don’t have the elusive 12v water pump that you need. Or maybe they don’t have any at all. That’s because these little pumps are really used a great deal in mainstream plumbing and building jobs. A better bet probably is to visit a motor home, caravan or boat supplies yard if you are lucky enough to have one within a reasonable distance. Or you could try to find one second hand or order one online from one of the big mail order and delivery websites, whether general goods suppliers or parts specialists.

To find a second hand 12v water pump you’d probably need to find a scrap vehicle that uses water, again such as a camper van or houseboat. The water pump that’s used for cooling engines is no good because that’s mechanically driven and the pump that powers a domestic washing machine is probably AC I think. If anybody has any suggestions for sourcing water pumps that run of a 12 volt supply I’d be very grateful if you’d leave comments which I will collect and republish for the benefit of all my readers.

The 12v water pump is a versatile device which unlocks the solution to a number of problems associated with remote or mobile lifestyles. There’s at least one 12v water pump in nearly every caravan, motor home or boat, for example.

The more unusual applications involve the use of solar power, wind turbines or non-mains water supplies.

If you are in need of several, perhaps many small 12V water pumps for a good price, it may be an idea to go to a boat supply store or a camper van fitters.

Or you may be looking for a 12v water pump to drive up to 4 water misters for maintaining a humid atmosphere in a specialty greenhouse. Wherever you need to pump a fair volume of water and have a car battery. A 12v water pump can pull from a water reservoir and provide cooling hydration through the misters.

Water Cooled Computer System with 12v Pump

Another use for a 12v water pump is in a water cooled computer system. Why would you want to cool a computer with water? Well because the usual electric fan can get too noisy if the processor is busy doing huge amounts of processing work such as rendering video or serving multiple users. Overclocked processors, modified to run faster will also generate a lot more heat and require a water cooling system, usually powered by a 12 volt water pump and a reservoir.
