I get the pleasure of replacing my vaccuflush hoses this spring.

While scoping out the job I saw a plate on the firewall that the hose is attached to or goes through. I can't really tell yet. That is my question, is the hose attached to this plate or does it go through the plate?

Trying to determine what my best course of action will be to replace.

Thanks in advance
 
I replaced one of mine a couple months ago. The first thing you need to do is find ALL of the access panels in the floor which provide access to the hose. The hose can't stop at the firewall. It runs from the head to the vacuum pump. Be sure do suck as much water out of the line with a shop vac before disconnecting anything. Then make sure you have removed ALL of the cable ties in all of the access panels. Then you can disconnect and pull out.

A few extra points:

1) Unless you like this task get a quality sewage hose. The cheap ones will allow the smell to permeate the hose in only a year or two.

2) be sure to seal around the hose where it goes through the firewall so bilge odors can't seep inside.

3) When you disconnect the hose to pull it out, plug the end to prevent the remaining sewage water from running out. Then check the access panels good and clean if it did. Otherwise the odors will take over.
 
The best thing to do before taking this project on is to get a really good pump out. I'm talking a cup of powdered Tide no bleach detergent in a toilet bowl full of water and then getting a pump out while you are holding the flush pedal down for two minutes. Then fill the holding tank up by running more clean water in from the dock side fitting and from the head. Keep pumping out until you are pumping clear, clean appearing water. Then comes the fun part. This initial step makes the job much more tolerable. Plug the ends of the sanitary hose as soon as you can. Hopefully you will be looking at "clean" water coming out of both ends as you disconnect things.

If the hose is "attached" to something, it will have clamps on it. Or, it should have clamps.
 
Thanks for the info. The cup of powdered tide is a good idea. I planned on definitely running copious amounts of water through the system before I did anything.
Plugging each end is a good idea also.
I bought my hose already from my local, not a national, marine store. This guy and his wife run the store and he has never steered me wrong before. I trust him. He said what I bought is what I need. It will not stink.
 
I say just use a toilet plunger... that'll fix anything with a vacuflush.
 
I changed my hose over the winter. It is clamped and secured every few feet. Some places in the salon were not accessible. The worst was the silicone tru the bulk head. I used the white sanitation hose as I was not doing this again. I wish u luck.
