.........................--- Master Water Manifold and Pressure Tank --

======================================================

The following can look a little confusing but it lets you direct water to the galley, head and cockpit from either the high 6 gallon gravity tank, the four 20 gallon tanks in the bilge using the high pressure pump or from a hose connected to the outside of the cockpit coaming at the yard or dock.

This manifold is mounted high up in the starboard side cockpit lazarette. Up in the bottom of the coaming. You get to it by lifting the hatch to the lazarette and it will then be right in front of you mounted to the coaming side facing the water.

On the other side of the coaming, from where you see “Water in at Dock or Yard” in the picture below, you can connect a hose at the dock or yard. This would give you high pressure water in the boat and you wouldn't be using the water in the tanks. The tanks can be filled either by taking a hose down to the manifold at the tanks that controls their output or you can fill them down in the boat from containers you bring from shore.

Depending on which valves are open or closed you can direct water to the sink or to the head or cockpit from a dock/yard hose or from the bilge tanks using the high pressure pump. You can also run water to the sink from the 6 gallon gravity tank up in the coaming just ahead of this manifold.

The valve from the gravity tank is opened to use it for the galley sink and the other valve in the preceding picture going to the sink is closed as it is from the high pressure pump or the dock/yard hose.

The boat had a high pressure water tank but it was rusted out. We bought a new one and then found out that you shouldn't use one with the high pressure pump that is currently in the boat. The previous owner must not of know that. We did buy a spare replacement pump and if it is installed then the tank will be put into use.

The picture above shows some of the original plumbing and what we added. We are not using water in the head at this time and also not using the cockpit shower but there are lines to those places and the sink in the head is plumbed to the new thru-hull there.

The picture above is taken of the outside cockpit coaming on the starboard side of the boat. There is a fitting there with a valve on it where you can attach a hose to at the boatyard or at a dock. With it you can have high pressure water at the sink when the hose is attached. When you don't have a hose attached this valve is kept closed. With it closed you can fill the upper 6 gallon tank with the boat's high pressure tank from the bilge tanks.

Also in the picture is the vent for the 6 gallon high tank. To fill or use the high tank the valve between the vent and the tank should remain open.

======================================================

Instructions to fill the 6 gallon high tank in the cockpit coaming:

1. Turn on the high pressure water pump.

2. Make sure the hose fitting outside the coaming is closed ....

3. Close valve from tank to sink (it is open in picture) ….........

4. Open all 4 vertical valves (they aren't correct in picture) ..

5. Water will flow from bilge tanks to high tank.

6. When water starts to come out of the vent line from the high tank close 3 of the valves leaving only the vent valve for the high tank open.

7. Reopen the valve from high tank to sink (see step 3)

This doesn't take much time. Just the amount of time for the pump to fill the tank and opening and closing the valves.
