vacuflush leak and smell in head unit

[cpoint]

Viper Thanks for the info. I will research the vacuum leak issue. In case of the Y-Valve, I am going to go along with your suggestion for now to bypass. When the boat is out of water for maintenance, I will have the issue fixed permanently. I did take some pictures (attached), it did look disgusting, I will be cleaning that next time I go there before working with anything.

I think that by posting that pic you have shown the problem.....the thru hull with the blue handle is open and allowing water to leak back into the system thru the pump and Y valve .....maybe there should be a check valve in that set up.....anyway just close the thru hull valve ( handle 90 degrees to direction of flow), I bet no more water.....oh and if you are not going to use that overboard discharge may disconnect pump wiring there, that way you are sure it is dead...

I was thinking about that, was not sure which way way open and which way closed. So this is open, that would explain

Yep definitely open, and if you're on an inland lake, that's an issue as the system should be disabled, and given that the hoses are still hooked up and hardware is in place, the seacock should be closed. Having said that, there still needs to be certain conditions in place for the tank to take on lake water as I mentioned above. There are many of these setups out there that are actually being used for overboard discharge off shore without the problem of their tank filling with water.

If you're in an area where you need to be winterized, get rid of the overboard discharge system altogether or it will come back to haunt you. What ever you do, don't leave the seacock closed for the winter.

Thanks viper. Yes I am thinking about getting rid of it, I do not believe I will ever need it. For now I will shut it off when I get back to it. One positive though the head tank is clean as a whistle, since I been having it pumped out every week for last 2 months with the water was filling in

The front head problems are now completely resolved, no smell no water filling. and because I had it pumped out so much, holding tank is clean and I am keeping it that way. But the back one has some issues. It started smelling when flushed. You can smell it from main cabin and outside (stern) briefly after a flush. So now I started to fill it water and vinegar, etc and have it pumped out and I see stuff being pumped out that came from previous owner I think. So I thought I would check it out but can't find the aft holding teank. I see the vacuum chamber and see the line going from that as well as I see the pump out line from aft holding tank, but can't see the aft holding tank. Not under bed, not in engine compartment, not behind wall. Any ideas. I see it in the manual, but do not see it in where its suppose to be. Can anyone clearly point me to right direction. I think I also need to replace sensor. The light is green after a pump out, but at same time red is flashing? why?

Cpoint it should be in the aft cabin under the carpet and under the second removable panel toward the door to the aft cabin. Make sure in the head that the vacuflush system is in the run mode and not the sleep/silent mode. Are you using a good tank additive for smell etc? If the system is in the sleep mode less vacuum in system and you will get smell if flushed, the admiral pulled that one on me just last week! Also I have suspicion there are charcoal filters on the waste tank vents that to date I have not located, but believe I read in a manual they should be replace annually, if I find them I'll update with the locations or maybe someone else may already know where they are and help us both out.

Thanks Mike. I do not believe there is any opening under carpeting in aft cabin. There is a panel sort of in the middle of the wall. I opened it, but there was sponge like material covering a tank, assumed it was gas tank (based on documentation/drawings), next to door of aftcabin I will have to take a look again, I did not notice any openings when I was there. About the silent/sleep mode, did not know anything about that. How do you turn that on/off? or know it's setting? And in regards to filter, please post here if you find it. Thanks.

Our 355 has the mode switches in the head next to the toilet. Carvers parts drawings show it centered in the aft cabin at the foot of the bed? The aux fuel tank should be behind the head of the aft cabin bed. Ain't this fun!!!! Mike

[cpoint]

yes its very fun, if you read my other postings loaded with problems, still have not taken it out for a fun ride since purchase As far as carver parts drawings, I do not think they are accurate, I am looking at the drawings and they are not matching real location on my 356.
