[C320-list] Water under holding tank

I had the same mystery water under the holding tank.
Which is also water under the galley cabinets.
Hand pumped it out several times.
Turned out to be continuous slow leak from 15mm ' quick connect' elbow fitting from tube to water heater threaded fitting.
So I cut out access opening in the bottom plywood of the galley cabinet.
Now I remove the lower drawer to look into the bilge for water.
Easier to hand pump water from here into the galley sink than to fit a suction tube down below the holding tank.
The boat has 2 bilges, the upper pan with keel bolts and the bilge area below.
Wish I had a cross section of this area. Tried to take pictures to make sense of this bilge area, no luck.

Had the same issue and found it was the pressure relief valve on the hot water service. The water does not drain into the bilge normally but I believe there is a mod you can do to allow this. Could also be the fresh water pipework, the push on fitting split, (I've had this happen too!), requiring replacement of all of those.

I am looking for some ideas. As I was reinstalling my supports under my starboard settee, of course I dropped my screwdriver under the holding tank. When I looked under the tank with a flashlight, I noticed a decent amount of water. I plan to go buy a wet/dry shop-vac tomorrow morning, as we are shoving off for Cape Charles early. Here are my questions:
1. Any ideas for the most likely point of entry if it is almost midship? It could have come from an overfilled forward water tank, as I have not been here since TS Isaias. It also could have been the TS.
2. Where does this water drain? I expected it to flow to the bilge; however, after emptying the bilge (I need to replace bilge pump and switch), the water has not moved.
I smelled the water (I did not have the intestinal fortitude to taste it) and it smelled like fresh water. I am assuming it is from the torrential rains. However, I have never checked under there before, as I assumed all water entering the boat would find its way to the bilge.
Any thoughts are greatly appreciated.

Jeff-
Does your boat have a macerator pump and associated thruhull?? My boat does not,? but if you had one the thruhull might be leaking?
It is possible that water could get into the structural grid below the bilge.

Actually another thought....my boat has water lines to the head sink that run right next to the holding tank (behind it next to the head bulkhead).? I realized I had a leak in one of these lines and need to replace both.? The leak fed water into my structural grid and eventually seeped up into the bilge around my keel bolts.

If that is the case, I think I could put a few drops of food coloring, maybe more than a few, to see if the water color matches the tank. It smells fresh so I do not suspect the macerator thru-hull. We did pump out recently and flushed the tank with fresh water (back through the pump out hole).
Thanks,
Jeff

I installed a second pump in that area on my hull 169. That lower bildge did not have a pump installed by Catalina. The water in mine usually comes from rain or washing.?Michael

You do not want to cut a limber hole from that compartment into the bilge.
In case of a spill with any of the plumbing, including the macerator, you want to contain the liquid.

I discovered water in that spot a year ago.? In my boat that is a low spot.? My guess now is that fresh water had been there a long time (source unverified) and simply had nowhere to go.? Without tasting, the smell was obviously NOT from the tank, so all I did was sop the puddle up with a microfiber cloth and wait.? It stayed dry so I was good to go.? My conclusion was the leak had been repaired by the PO or was a one-time occurrance.? Good luck!? Neil Kornblatt #973? Harmony

Jeff,
I'm close to hull numbers with you, and I too have been getting some water
in that area for a few years now, yet to find the source. I was also first
concerned it was waste water, but mine is clearly not (no smell, very
clear). I keep a Lithium battery powered DeWalt wet vac on board, and once
a month suck up the water to prevent a bilge smell from that area.
A while back, someone posted that leaking/overfilling after tank can cause
water to pool there.
If you find the source, please share.

We used to get this on my previous 320 (#303) after sailing in a fresh wind on a port tack. I came to the conclusion that water from the bilge was spilling into this area but getting trapped when the boat righted
The battery cables pass through the floor matrix to reach the starboard side then up to the electrical panel
That floor matrix doesn?t seem to me to be water right. There are couds at each end so once the boat is heeled over water can get in. Never cured it but my new C320 (#366) doesn?t have the same problem

Graeme-
Did you heel a lot on the port tack?? Could you have been taking in water around the side mounted holding tank vent?? That would be located where such a leak might settle near the holding tank.?
