The 12v Water Pump for the RV:Showering that Travel Dirt Away

Anytime that you see an advertisement for an appliance that works at 12 volts DC, you know that they've thought of yet one more indulgence for the mobile enthusiast: the car lover who likes to kit out his car with every known electronic device, the boating enthusiast who loves the idea of showing off how every convenience of a normal home finds a place in his boat, and of course the cross-country fan who loves the idea of towing his own RV home all over the country. Appliances need to run at 12 volts DC to be able to accept a connection to a standard car battery, the only reliable power source when you are a hundred miles from nowhere. For the boat or RV enthusiast, the convenience of running water, sometimes even a shower at the touch of a button, can seem like a king's life; and this is made possible by your trusty old 12v water pump.

In motor homes and on boats, the 12v water pump is used for more than one reason. Boats have a tendency to collect water at the bottom, the area known as the bilge. It is unhealthy to allow water to stagnate around there, and no one ever has the stomach to muck about down there to bail it out. A level-activated automatic 12v water pump can be just the solution to this problem. When coupled with a float valve, these pumps can kick in whenever water collects in there, and can get rid of it overboard on their own. Above-deck, in the living quarters on the boat or in the living quarters on the RV, a pressure-activated 12v water pump can kick in whenever you open a tap. The pump is connected to its own car battery, and it can perform double duty, pulling in water from a sump outside, and then pumping water upstairs to the living quarters.

Owners of 12v water pumps often notice two annoying qualities to their ownership experience: the water out of the tap doesn't run uniformly, it pulses instead; and of course there is the problem that these pumps can be quite noisy. Modern 12v water pumps tend to be made with hard wearing plastic parts and not heavy bronze like before. While this does bring down the noise level quite a bit, careless installation can often broadcast the noise, and sometimes even amplify it quite a bit. Most of the rules for how to properly mount your water pump are pretty easy to think of yourself. Make sure is that the pump is mounted on rubber feet: it should be connected to your RV's plumbing with flexible hoses that do not transmit the noise to the plumbing,the pump should not make contact with the frame of your vehicle through anything other than its rubber feet, and so on. If your pump happens to be quite old, there are rebuild kits available too that can help you replace the parts that are most likely to be worn out.

But if the water put out by a 12v water pump has a pulsating quality to it, that is quite normal. It is just that these pump are always set to cut off water at a certain pressure; it checks constantly to see if it finds the pressure going out of its range. Whenever it senses that the pressure is too much or too little, itcorrects for this: hence the pulsing effect. Traveling with your own plumbing system can be quite a heady experience: especially, everyone must try the feeling of taking a shower, parked on a desert road. These pumps come very reliable these days, and with common sense applied during installation, all should go well.
