Unintended Water in the Bilge of a PSC 34

In December I found another way to get water into the bilge of my Crealock 34. While looking for the source of a water leak in the galley, I closed the ball valve behind the galley drawers that shuts off flow to the thru hull on the port side that is just above the water line. That thru hull is the exit both for my electric bilge pump and for the deck drain on the port side. The water from the bilge pump gets to the valve and the thru hull via a vented loop mounted against the hull just below the deck. The water from the deck drain (which is higher than the vented loop) joins the hose from the electric bilge pump in a wye between the vented loop and the valve. In the rain with the valve closed water from the deck ran backwards over the vented loop and backwards through the bilge pump filling the bilge.

I heard the water running into the boat, saw what was happening, opened the valve, and pumped the bilge dry. My guess is that if I had not caught it, the bilge float switch would have started the pump and pumped the water back out onto the deck. In any event closing the valve might have unintended consequences, especially if the bilge pump did not start.

Bill, PSC must have made a change along the way in this regard (maybe for the reason you describe?). My '97 PSC 34 has two separate / dedicated thru hulls, one for the deck drain hose, the other for the bilge pump hose.

My '91 PSC 34 also has two separate thru hulls.

Ditto on the two separate thru hulls on our 1990 34.

Bill - what is your hull number? I have #142 and also have the two thru hulls.

My current favorite way to fill my bilge is to fill my aft freshwater tank. It took me a while to summon the courage to taste the bilge water to verify that was the source.

I am guessing I will find the fiberglass is cracked. Anyone have a suggestion for which compound to use to re-seal? I am thinking something flexible would be my best bet. Maybe food safe silicon?

Are you sure it's just not overflowing the tank via the vent? I don't know
where the vent is on the aft tank of the 34.

I was doing the same a few years ago, maybe it's not a cracked tank.

My aft freshwater tank was leaking and i found it to be the plastic thru hull was cracked that penetrates the tank from the freshwater deck fill. I took the lid off the tank and replaced the fill, vent, and freshwater suction thru hull fittings for that tank all at the same time (why not since i was already in there).

I'm guessing it may be slightly different for a 34 than an Orion, but my aft tank is also under the quarterberth.

PS. If you don't have them already. when you take the tank lid off install two screw out watertight deck plates into the lid so you can get full access for cleaning and inspecting the tank. Get them big enough let your arm in.


Dictated, but not read.

RainDog, my boat is hull number 118.

It is good to see that the later boats do not share the problem.

I too have had the bilge fill with fresh water. In my case the branch broke off a plastic tee under the sink filling the bilge. It does take a lot of nerve to taste the bilge water.
