Water leaks



This is the offending leak.  The boat has copper water lines from the hot water heater and go under the galley sink.  The copper lines also go to the aft head sink and the forward head sink.  They are in good shape but, and there always is a but, they are metric.  Oddly enough the fittings used to connect to the hot water heater are standard fittings.  That hose attached to the copper line with 2 hose clamps is 1/2" and the copper tube is a little smaller.  Doesn't matter says the previous owner, clamp the shit out of it.  Well guess what?  It leaks.  The copper line runs under the floor boards and when it rears it's face under the galley sink, there is a connection there.  This connection is 3/8ths.  Go figure.  So I replaced that short run of copper with reinforced 1/2" tubing and clamped it.  No leaks.  Next job is to rerun all those lines under the sink and get some really storage out of that area.


So this is a view under the sink but not a good one.  Hard to get a sense of the clutter.  Anyway, Appa has 3 water tanks and the hoses run from the tanks to under the galley sink.  They go into this manifold so we can switch from where we are drawing the water from.  From the manifold, the three hoses become one hose that runs to the water pump and from there to the water filter.  Out of the water filter, the hose splits to the aft  cockpit shower then splits again to the watermaker flush system, then splits again to the forward head cold water and then splits again to the foot pump and then splits again to the galley sink.  All of this happens under the sink.  Crazy.  I am trying to figure out how to fix this.  I think I have a good plan.  We'll see.

 This is the foot pump for the fresh water system.  This is how stupid I can be when thinking about boat systems.  I thought that the pump was failing because when I pumped it the lever would not spring back after being pushed down.  Well turns out that these pumps are supposed to be BEFORE the electric water pump, or preferably on a waterline that has no other pump.  Basically the water couldn't get into the foot pump because the electric pump was stopping it.  If I was to turn on the electric pump and let it run, the foot pump would work.  Duh.  I also think that this foot pump might be the source of my gremlin in the electric water pump. I keep losing pressure and I'll bet that this is the cause.
I was about to pull this foot pump out and then rebuild it.  Then it hit me while I was drawing the fresh water pipe schematics.  I won't post that chicken scratch, as I am the only one who can read that shit.
