2001 356 wash down question

[MV Necessity]

IMG_1677.jpeg

HI everyone. First time poster here. I have a new to me 2001 356. On the bow (near the anchor roller), I have a wash down outlet. (See picture 1) On the aft deck, I have another wash down outlet (see picture 2). I assume that these are fresh water wash downs because the wash down pump breaker on my 12v panel is blanked (see picture 3).

When I open these outlets, I get nothing. I have left them open hoping to have air bleed out of the lines but I still get nothing. Does anyone have any suggestions on how I can get water flowing through these outlets? Am I missing a valve somewhere? I appreciate everyone’s help!

My fresh water wash downs are looped into the boats main water system. If yours are fresh water wash down, they would run with your main water pressure switch on the panel. Ensure you have water in your main water holding tanks

By the description you gave it sure sounds like potable water wash downs. Reminds me of the first time I used those valves, could not understand how to operate them until I figured out they were quarter turn valves and not a standard turn a few revolutions to open or close spigot style valve. The plaque beside them should say fresh or raw water wash down. This is assuming they are the same or similar to the ones on my boat.

Welcome to the forum.

Could there be an isolation valve for this washdown system somewhere? I would guess it may be near a feed point from the main tank between the tank and the washdown valves so winterizing would be convenient. Any of the pumps are pressure triggered so when a valve opens you should hear a pump start ( if powered ), even a small leak will create intermittent pump cycles. I will say those plastic valves can break internally.

We had raw water wash downs and the pump just went bad ( no water and no noise), went down and clobbered it and got it working but had to be replaced....that system had a thru hull valve to isolate.

Hopefully someone with the same boat can help, but you never know what has been altered by previous owners etc.

I have a 2001, 356 as well. As mentioned above, both spigots are tied into the boat’s main water system…unless a previous owner did some modifications. What happens when you are connected to shore water? Both spigots should work when connected to shore water or drawing water from the onboard tank, assuming there is water in the tank and the pump is in working order. I had to replace my pump a couple years ago. Did it myself and it is NOT a fun job.
What about interior spigots, galley and heads…are they working? They all should be working or all NOT working.

FYI, one of my spigot handles broke, so I replaced both of them. After some searching, I found a universal one at Lowe’s that fit. Google Blue Hawk, part #0041960.

quick question...do you have an ice maker and sink on the aft deck? Are you getting water to it as the same water line feeds it and the aft wash down.

So, what’s the latest on this? Inquiring minds want to know.

Sorry for the delay in updating this. I got hijacked by another project. All of the interior faucets work fine. I do have an ice maker on the aft deck and it also works fine. I feel like there has got to be a valve somewhere that I just haven’t found, yet. Or, It is possible that a previous owner disconnected these washdown lines for some reason (a leak perhaps). The water pump is behind and under the port engine. So, it looks like I’m going to have to get my head lamp and go bilge diving to see what I can find down there!

Ok, do any faucets work on shore water? Do they work from internal tank and pump? We need better info.
If you need to replace the pump, I’m assuming it is mounted on the bulkhead between the engine room and aft cabin. If it is placed like mine is, you need to be a midget contortionist to change it out from inside the engine room. My boat has an opening in the bulkhead, I’m guessing about a 1’ - 1-1/2’ square. I changed mine out laying on the floor in the aft cabin with my head and arm inside the opening. If I recall, I could only get one arm inside so I had to do the job one handed. It was 3 years ago, so my memory is a little fuzzy, but it was a very difficult job that took a couple hours to do.

Nothing works on shore water when the pump is not turned on. Except for the wash downs, everything works fine from the internal pump and tank. The hot water heater works great and as long as the pump is turned on, the faucets in the heads and galley all work great.

I know what opening you’re talking about in the aft cabin. I wondered if that would be the best way to get at the pump.
