A dripping faucet can quickly drain freshwater reserves while dry camping.  Drips are generally the result of a worn seal.  Tools needed to repair a leaking faucet include a screwdriver, WD-40, slip-joint pliers and replacement washers.

Start by turning off the water supply and be sure the water pump switch is turned off.  Locate the screw at the faucet handle, which may be hidden under a disc that snaps or threads out.  If the screw is stuck tight, use WD-40 to help loosen the screw.  Once the faucet handle is removed and the assembly is exposed, use pliers to remove the packing nut.  Twist the nut in the same direction as the faucet turns on.  While removing the nut, be careful not to scratch or damage surrounding fixtures.  Locate the washer and remove the screw holding it in place.  Examine the screw, stem and washer and replace parts that appear worn or damaged.

You will need adjustable wrenches to replace a whole faucet assembly.  Assure that the new faucet will completely cover the mounting holes from the former faucet.  Prior to removing the faucet, turn off the incoming water supply, including the water pump switch.  Loosen nuts from under the sink, disconnect the water supply lines and remove the faucet assembly.  Carefully clean the mounting area.  Position the new assembly in the mounting holes and carefully align all the gaskets.  One by one, install washers and nuts on the studs and hand tighten.  Finish by tightening the nuts using a basin (spanner) wrench and reconnect the water lines.

The bathroom sink faucet will usually also include a pop-up drain plug.  Locate the place in the linkage where it can be disconnected from the faucet, and follow installation instructions the new assembly package for reconnecting the drain linkage.  To replace the shower faucet you will have to access the pipes through a wall panel.

Frequently inspect the outside shower faucets to assure they are snugly closed.  A slightly opened faucet will waste water and force the water pump to frequently cycle.

The spray hose at the kitchen sink may wear over time and produce dripping.  Dry the hose thoroughly and inspect the connection at the head.  If water appears at the head, tighten the connection.  Continued weeping may require replacement of the head and hose assembly.  Tightening the connection will usually repair water at the spout connection under the sink.

At least two times per year, remove the aerator screen in the faucets and spray head.  Flush the screens with a strong spray of water, using caution to prevent parts from washing down the drain.  Dry the screens and then clear away build up using a stiff wire brush.  Stubborn deposits can often be removed by soaking the screen in vinegar.
