Dick,
You probably have a 1 1/2 straight PVC coupling that dumps the gray. I got fittings at the Depot to reduce down to a garden hose male and then could just hook up a hose and let er run. Your vintage may be different.
Similar to this then reduced to garden hose. I didn’t glue it, just pushed it in when needed.

i WISH we had a Crestron. We have something called Logictech installed by previous owner. Its only suitability is to be placed at the forty yard line……

Jim & Chris, so sorry….didn’t think it could get worse. Jeff’s electronic whiz kid is supposed to be pretty good. Geo.

We only have two days

I keep this little guy onboard. Connects to any of our coaches.

That cap won’t fit a liberty you would need a adaptor to fit the thedford connection, but on a Liberty it has a grey pipe all by it self , the black has the big pipe like that cap but it’s a thedford
Dick if you let the grey just come straight out under coach if you are on grass or dirt you can get stuck in the mud when you get ready to leave you should get hose and put it out away from coach , if on pavement it is not a problem
-
What pipes, adapters, fittings, hoses, thedfords, are you guys talking about. Dont you just have a button you push and the dump hose pops out and stopes about 6in. from the inground septic connection provided by the campground..I,m confussed.

Something I’ve never given much thought to but if a coach does not have the capability to hold its own grey water and discharge it at a later time with a garden hose that would be a deal breaker for me.

Vantare also uses Thetford connections, but they are available. We use ours frequently.

I’m having trouble understanding how sewer tanks and their outlets can become deal breakers.
I’ve had both kinds, separate tanks for black and gray, and combined. I have had gray water bypass and a macerator. Maybe there are some other variations but I think I understand the positives and negatives of each.
I have never wished I had something else. No matter what waster water system and drain configuration I have had it worked. 99.9% of the time when it was time to dump I opened the valve and the waste drained into the sewer connection. It might have been one of two tanks, or a combined tank, but either way emptying the tank was simple.
If I had two tanks I drained the black first, and flushed the hose with the gray. If it was combined i just drained the tank and flushed the hose with the water faucet in the bay. On my two tank bus I never had both tanks fill simultaneously. One or the other filled first and that determined when I had to drain the tanks, but it was nice letting the gray water flush the hose. When I had a single tank as I do now that one tank decides when it is time to dump. It is less of a hassle with a single tank in my opinion.
I have a gray water by pass, rarely used because of growing regulations. Way back when we first started fewer places objected to the gray water discharge on the ground. Now it seems there are many more. But when I can use it my time between dumping is extended. I have had one that just dumps straight down, and one with a hose connection. If I used the gray water by pass more frequently I would add a hose connection to the by-pass to carry the water away from the coach.
The macerator is a nice but rarely used convenience. When dry camping in places where there was a sewer cleanout it was nice being able to pump my waste into it if I could not get the bus close to it. But that situation is equally rare. I also have two side discharge for my holding tank, but have never used the passenger side.
Bottom line, I don’t care how my holding tank is set up. Or for that matter if I have a macerator or gray water by-pass. They are conveniences used so rarely they would have no impact on my coach purchase decision.
Maybe I don’t go to places where a specific type of holding tank or sewer system is required.

Before this extended conversation on waste tank variations, I had never given it a second thought. I was aware of the two options (single/dual) and that sometimes a macerator is part of the system. Other than that, I would happy to accept whatever the configuration was if the rest of the bus was in line with my expectations & requirements etc. Personally speaking, it would be like rejecting a bus because it had an LCD TV instead of LED. I think there are far more important things to worry about, as well as there not being that many buses to choose from in the first place for any given age & condition.
I do like the idea of the grey water bypass though, but wouldn’t lose any sleep if I didn’t have it.

If the coach is used exclusively in RV parks then the tank choice would be immaterial. My experience is twin tanks makes my life much easier if I dry camp much. If one has not taken advantage of the separate gray tank capabilities when dealing with gray water then you would not miss anything having a single tank. I have found that having flexibility makes my life much easier and twin tanks gives me that flexibility. I have used this feature to its full capabilities with twin tanks. To me it would be a deal killer to go back to a single tank that I had in the 2 Newells that I owned. This might not bother anyone else but this is my experience.
-
You say it makes your life easier when dry camping, but never explain how that is so.
What exactly makes two tanks work when dry camping as opposed to a single tank? It must be a huge benefit to make it a deal killer.
-
Andy, it’s not quite like rejecting a bus over its TV. That can be easily swapped out. I’ve done it. Reconfiguring the plumbing system on a bus however would take a little more time and money.
Jon, for me it’s a deal killer because of the benefits associated with how I use my coach. For example, over this summer the coach was approaching full on the grey tank and a load of laundry was being done, no sewer connections were available. We can all see where this scenario is going…the tank was full just as the washer decided to dump. So I had a few options: (1) let the tank backflow into the coach (big mess) or (2) open the grey tank for a few seconds and let it go on the ground. If I had a single tank option 2 might not have been an option.
I also use my coach without reservations. Meaning I might decide to head to CO and not make any reservations along the way. Now I might stop in rv parks or I might stop at a rest stop. Depends on my mood. But the ability to hold all my waste, black and grey, with the option of discharging only the grey water is a necessity for me. Therefore a single tank would be an inconvenience for how I use my coach.
Both configurations work without hiccup. Simply put they hold waste for disposal at later time. I just like the option to dispose of the grey water while holding the black until I get to a sewer connection.
Similar to the bus air debate. Seems to be a deal breaker for many coach owners. While at the end of the day all coaches have the ability to cool themselves going down the road.

Regarding dual tanks vs. single tank. At most dry camping events you are not allowed to dump gray water. However, late at night I understand some people drain their gray tanks. This allows them to get substantial longer times between dumping or getting pump outs. While I would never do this…. the opportunity to do so would be very important to me. With a single tank there is no flexibility in this situation. Therefore, it would be a deal killer for me.
