Holding tanke

That is a good idea Ollie.

Jeff,
Do Prevosts only have one holding tank, as opposed to other DPs which have both a grey & black tanks?
-
Tim Libertys only have one tank some others have grey and black two tanks , you can bypass the grey water to not go in black tank so lots of room for black water. Sorry I know you asked Jeff , I replaced my black tank with new stainless tank it had a aluminum tank they are no good for black water earlier models had stainless tanks before 1997 not exact sure of that date might be a little one way or other but after that they had aluminum tanks , and they rot out you will have to replace it
-
Our 1999 Liberty (1998 chassis) has a stainless steel holding tank, at least that is what Jeff told me when Peter standing next to him at Eastern Tennessee Luxury Coach in January.
For the life of me, I don’t understand why a coach/motorhome builder would install separate grey/black tanks. The only reason I can think of is having a separate grey water tank gives the owner the ability to possibily “dump” the grey water separately without needing to dump it in a sewer of some kind. But in my eyes it takes up additional room in the bay, additional plumbing to separate the two, more weight for the additional panels, more seams to leak, etc.

Dick what are you saying my mind is going ,, I dont think so !!!!! I said its some where in that year .. I have replaced tanks in 1999 prevost 2000 liberty’s that had those aluminum tanks !!!!!!!! I have had coaches with both and I liked both types , fits in the same bay but gen is not in the same bay as the tanks like the Libertys , some of the coaches I have had , had two water tanks and black tank and grey water tank, one water tank and grey and black in same bay and in other bay next to it had another water tank , gen in another bay that coach had no over the road air but did have more room in all the bays for storage than the liberty I have now but it has over the road air takes up two bays!!!!

I think each converter has their own way of designing the holding tanks.
I have had both separate and combined. If the tanks are separated the only advantage I can think of is once the black water is dumped, following with the gray water tends to clean the hose. Other than that I’m not sure of the benefit.
I now have only one holding tank, but do have a gray water by-pass. That is a feature that makes sense because if access to a sewer is unavallable for an extended period it allows all waste water except from the toilet to drop to the ground.
-
I have heard that there is a requirment by the RVIA (recreation vehicle industry association) that mandates black and gray tanks,I also have heard that some states like Oregon has a law that mandates the 2 tanks therefore Marathon will always have 2 tanks.Liberty cannot be a certified RVIA manufacturer with only one waste tank.The S&S must have the RVIA seal or the lenders will not deal with the product.This is what I have heard over the years about 2 tanks,it might not be the truth.
-
Interesting background from Jack on the subject.
I wonder what the logic is for requiring separate tanks. Often requirements like this are based in some kind of logic; whether flawed or not.
-
This sounds crude, but when the tanks are separated there is less water in relation to solids in the black tank. I think there is a significant benefit to have a higher volume of water relative to solids to slosh everything around so when dumping the tank it carries the solids out of the tank.
I will use the gray water by-pass for example when I am not going to have access to a sewer connection but under all but those instances I want all the waste water we generate to go into the tank so there is a vigorous flow to carry the poop downstream.

I have a 1999 Liberty, Jeff will be replacing the aluminum tank with a stainless one in about 3 weeks for me. I also would have not noticed the leak if Jeff had not pointed it out to me. Little black spots on the tank with white corrosion running down.. I am glad he found it… Can you imagine the mess……………………….

getting a new holding tank installed today. the white spots had grown in size and number since last fall. figure would be best to do that now, rather then wait and have ot fail while we are on the road this spring//summer/fall.
josh and dan were wishing peter was still here to help them out 🙂

I cannot think of any part of that process that is fun. The guys doing it need to get hazardous duty pay.
