Vacumn Leak

I have the same problem . Bought aftermarket parts off inter net was the worst thing I could do. They were junk. I had more leaks then i could count. Bought the right parts and that fixed all the leaks
 
Hello, I am having a problem with my master head. I replaced everything from the floor up in the head, down below I replaced duck valves, I replaced the bellows, I replaced the vacuum switch twice because Dometic and a local repair shop said they are having major problems with their switches because they are no longer made in-house. I checked with a vacuum gauge and the leak is down below. To make matters a little worst while the pump is running I could just slightly touch the vacuum switch and it would turn off and hold the vacuum for hours if not days, meaning it is right at the edge of making enough vacuum. Now it will not go off at all, so the next step is to change the seal at the elbow of the accumulating tank. A little crazy but I am thinking of going ahead and replacing the hose as well, a couple of suggestions were to hook the hose to the new hose and pull through. Sounds too easy, any thoughts would be appreciated especially from somebody who has done it in the past.
I just did a huge detailed write up with pics on replacing the hose on my 330 that I just did this weekend. In doing so I found the hose to be severely weathered and dry rotted. Apparently sea ray left the hose outside in the sun for a long time before it was installed on my 08 330. I also found out during the replacement that they had installed 3” screws on the aft access door which is 1/2” thick plywood….. so at least 1.5” of screw was in my sanitary hose from the factory.

I was able to do this all myself by connecting the new hose to the old with a couplet I found online. It was the biggest PIA to date on the boat. Those of you thinking about doing it see my post it may help.

You are certainty right about the PIA part.... I did the same to my boat but replaced the bulk of it with PVC pipe. Page 2 of this link gets into the actual work.

@BobFino - PM me your email address and I can send you the instructions for replacing the sanitation hoses...

too big to post here...

I haven't checked in here in quite awhile, but a slow day in the office afforded me some time. As I was reading through this thread I was wondering when you'd weigh in....and here you are. I knew you had the instructions from Sea Ray. I don't envy anyone replacing sanitation hoses on a 58. If we had kept ours it was the one job (other than MAN maintenance) that I would have definitely contracted out. Hope all is well, my friend.
