Chameleon has dual pressurized water systems onboard.
The potable system consists of a filtered control manifold that allows switching between up to 3 water sources (2 currently installed). This manifold feeds the pump which then distributes water through another manifold that controls where that water ultimately goes.
We have a 10 gallon bladder stored under the aft dinette bench.
The main water tank is a 25 gallon poly tank installed under the starboard side vberth. Filling the tanks is accomplished via a deck mounted stainless flush mounted deck fill.
The secondary water system pumps seawater to a seperate sink faucet for times when you don't necessarily need fresh water. This is controlled by a foot switch mounted at the base of the galley and covered by a strip of aluminum allowing hands free operation.
