[C320-list] Replacing Water Hose to Cockpit Shower

[Jeff Hare]

Hi,Think of it this way.There is one line from the forward tank that passes down the port side, under the sink and then pops out into a valve where the water pump lives.The aft tank has a line that crosses under the prop shaft into the compartment with the pump and into a valve.The output of both valves join and feed the water pump.The output of the pump runs back out along side the forward tank feed and ends under the galley sink.So the project is simple.  You cut the forward tank line to end and join into a valve under sink (instead of going back to the pump).  You replace the line from the aft tank with a longer one that goes from the tank, into the compartment with the pump but continues out and up to a valve under the sink.NOTE: The leftover piece from the foreward tank that heads back to the pump area is frequently a bit too short to reach between the output of the new valves under the sink and the input to the pump. Otherwise, that's the line that feeds the pump. It's easy to tape a new longer hose to the old one and pull it through. It is a piece of cake for those non-gridliner (deep bilge) models to just poke a new line from the pump area to out under the sink.  So in summary, you need to run one new line from the aft tank up under the sink.  And possibly replace the fragment of the old bow tank line between the sink and pump with a slightly longer one.

Wouldn't you need to run two new lines to under the sink. I'm thinking...1. Line from the forward tank to the aft valves gets shortened and diverted to under the sink new valve location.2. Line from the aft tank gets extended forward to the new valve location.3. Line from the new valve location runs aft to the water pump under the aft cabin bunk.4. Existing line from the water pump to distribution points remains unchanged.On 6/29/2022 12:09 PM, Jeff Hare wrote:> BTW, this is an excellent time to do the simple change to move the water tank valves up under the galley sink.  It's super easy to push a single line from the water pump and have it pop out under the sink.  This was one of the first projects I undertook and it was ridiculously easy for a novice.>> Then you can simply swap tanks using the little access door under the nav station.  I understand some older hulls don't have this access door, but it's easy to add.>> Cheers.> -Jeff Hare>
