The time has come I plan on replacing all my hoses this is a big job and will need a lot of hose. I not it is best to use as much PVC as possible but where I need to use hose would the Max Flex hose be good enough the top of the line hose is crazy expensive. If there is some other brand that it as good but cheaper I would love to here about it.
Not sure if I want to do this job now or in the Spring. Any pros or cons to this? Maybe the hose is harder to work with in the Spring because in has been cold for so long.
Thanks
 
Thanks Jim this is the more expensive hose I'm hoping someone will tell me that the model below this is more then adequate:) They come in 50' rolls and I'm thinking I will need more then 50' I really don't want to spend $900 on this hose! There are so many bends in my system I'm not sure I will be able to use all that much PVC which is unfortunate being it is 1/10 the price.
 
Dave that is what I have used the SeaLand Odor Safe sanitation hose. Look at it this way using high quality sanitation hose will increase the time between replacing the hoses they don't last forever. I did my original hoses in 2006-07. 6 season later I just replaced them but it was because I changed 80% of the hoses routing & configuration and since I was already scraping knuckles and hurting the arthritis in my hands, knuckles and fingers I wanted to restart the clock. I really hate working on the sanitation system and I have the final configuration now this should last a long time. Since the sanitation hoses are so expensive I always make sure I don't have any residual effluent in the hoses, no low spots and when leaving the boat I flush the freshwater head 3 times the last time I add an enzyme treatment.

Dave, no way you should need 50' of hose, especially if you also using PVC. My vacu flushes are right under the hatch by the galley and MS. Hose from MS head to that, maybe 3'. Guest head is mostly a straight shot. Estimate 10' of PVC with one elbow and another 3-4' of hose from there to vacuflush. From the vacuflush it with be a foot of hide each into a Y and the 6' or so of PVC to tank. From the tank it is a straight shot through the bulk head to engine room. Straight from there to port side and straight up to discharge. Total, 15' PVC with a 90 and a 45 degree elbow. Imay use 6" or so of hose to connect pPVC to discharge. So 10' of hose should be more than enough. If you do this also replace your vent line with PVC. If possible I am going to increase the size of the vent line too.

I plan to do mine when I pull up my floors to put the wood floors in this winter. I am thinking of adding a new waste tank monitoring system at that time too.
 
My problem hoses are the feeds to the pump out. These hoses are the low spots and fluid is always sitting in them. I too flush the lines whenever I'm leaving the boat but never really stopped to think about the pump out lines and the fact that they are gravity feed to the pump and there will always be waste in them. The hoses feeding the tanks seem just fine but I will replace them as well. I believe the hoses to be original making them 16 years old I would say it's time! I have seen this hose for as little as $5.79 a foot but I still think I can do better. Again where I can I will try to use PVC but this is likely to be limited do to the bends. It may not even pay to attempt the PVC it may end up taking more time then it is worth but I will try.
 
John if your tanks are poly/ plastic ABS type the Raritan multi-tank system works well. I use it on my boat to monitot the holding tank and 2 freshwater tanks. They are easy to install,. calibrate and maintain. I can usually tell when it's time to clean the holding tank when the sensor starts to read higher then normal. I have never had to recalibrate or clean the Poly freshwater tanks.
The negative long term for me is I would love to see someone make a foil strip sensor system for multipule tanks like the Raritan I installed but be able to output in NMEA2000 sentences.

I used one 50 foot roll for my 47. Yes, you should use the most expensive hose, the cheaper stuff is not good enough.
 
Yes you can buy it buy the foot for $9 Per foot but it's about $6 per foot if you buy elsewhere by the roll.

John I have a very different set up then you. I have two waste tanks both feed to a y valve in the engine room then to the pump out and macerator. Each head has it's own tank all of the hoses seem to have huge bends in them not much in the way of straight runs. I hadn't thought about replacing the vent lines I suppose they may be an issue as well but I'm not sure.

John I pulled up my carpet to get access to the hatches and man did it smell in there! I believe I have a picture of my wife cleaning the bilge I'll see if I can find it. The two waste tanks are in the center line of the boat and the water is off to the side. Every other Trojan I have seen have one waste tank and one water tank in line with where my waste tanks are.

I have two long hoses to the engine room and then I have to vents yes I have two vent filters also.

The good thing is the carpet is like new and came up and lays back down without any damage.
 
Well now you have me wondering what I will find when I pull up the floor :-). Do you also have two tank lever monitors? I have looked in the space on the starboard size and have nothing there. It would seem strange to put 100 gale of water off to one side like that. Especially since it has a bit of a v shape to it. But looking at your space, I do not see how a 100gal water and 100gal waste tank would both fit in that space. Hmm, questions, questions.
 
John I still have not seen what's under my galley floor but I believe I have two water tanks connected so they self level port and starboard. Yes I have two waste monitors one in each head. The hoses are real tight to the floor I don't see how I will be able to slide PVC into that space it is to shape a bend I would kink the tube trying. I have my hands full. I have looked at a friends boat which I believe is what you have. Both the heads feed into one tank through a y fitting and one output much easier to do and his hoses route differently and I think it would be easier to use PVC in his boat less turns and bends. I would consider rerouting but I need to get the old hose out anyway so it may be easier to just pull the new hose through at the same time yes more costly but may be quicker.
 
So I am wondering if (contrary to the manual) I have less than 100gal of each then.

Btw - thanks for posting the picture.
 
I don't believe you have a 100 gallon waste. Water yes but not waste I forget what it is but it's not that big.

I just asked a friend, He thinks his is 88 I'm not sure it's that's big but in that ball park.
I thought it was more like 60 but I'm not sure Hogan and Starry would know for sure!
 
I just pulled up my Owners Manual. I have that and the specs scanned and online in a blog. It is only 88 gallons for the holding tank. I thought it was more.

It is funny in that appearance wise my boat is the same as yours inside and out. However, underneath it appears to be more in line with a 98.
 
This is the schematic from the owners manual. Oddly, this shows two tank. Yet the plumbing on my boat is nothing like this. The spec sheet for the boat says one 88 gallon tank. But the owners manual says 104 gallons. I also do not have the overboard discharge pump or discharge.

Here is the one for the fresh water, which appears to be in the same location as the waste tanks (and people wondered why I would not drink the water tank water) . I also only have one water heater and no plumbing for a second.

I believe the water is 104 and waste best I can find is 88. The waste is in front of the water but in line. My friends boat like yours doesn't have a discharge pump either the pump out hose look very difficult to replace there doesn't seem to be access. Looks like it is routed behind the guest stateroom closet and up to the gunnel, not sure how you replace this? But it is a shorter length of hose. My hoses go to into the engine room the route up to the pump out and or to the discharge pump. I have a lot more hose to deal with and again two vent hoses which vent all the way in on the bow my filter(s) are in the anchor locker. So many differences for better or worse I'm not sure.

88 gallons is a lot of poop to haul around! Mine is 14 gallons.

When I replaced my hoses, I pulled them out and measured them so I would only have to buy what I needed. Of course this meant I had to buy them locally at the high priced store so I'm not sure if I saved anything. Next time, I'll know. It was 22 feet.
 
Ron I thought about them and measuring them but I'm hoping to pull the new hose through as I remove the old hose. I'm thinking I will pick up a couple of couplers and glue them in so I can pull the new hose while removing the old. Granted I will waste a small piece of hose and a connector in this process but I hope it would make life a little easier. I can't see the entire run it goes under the bilge making this a project I need a little luck for this to go smooth which is why I'm thinking of paying someone to do it for me. I not sure my back will permit me to do this job.
