House sanitary line to trailer

Buy the pump. I like the way the camper travels with extra weight so I bring my waste home. I put a 12 volt outlet right by the dump valves, plug in the pump, hook up the hose and in a couple minutes all gone. If you go into the 2" line you may plug it. I would not want to clean it up.

Why don't you just say black water too ?
You cannot dump a BW tank thru a 2 inch line, w/o a chopper pump, period !

I have to agree with this. Going from a larger to a smaller line with sewer flow violates every rule and code - for a good reason.
Use a macerator and do it right. You won't be sorry and it may even cost less.

Should be pretty simple to dig down a foot or so and saw off the 2" abs/pvc cleanout pipe, then glue a 2"x 4" abs/pvc reducer onto the 2" pipe and then glue on a short piece of 4" pipe, then a 4" abs/pvc threaded female cleanout fitting so it ends up flush with the ground......then you can screw your threaded RV sewer hose hookup elbow into the 4" abs/pvc cleanout fitting just like you do in an rv park.....put a 4" abs/pvc plug in it when you are not using it....thats the way I would do it anyway....abs/pvc is really easy to work with and fittings are cheap & easy to find at any hardware store.....

I wonder if it might be an alternative for you to get a macerator pump that can pump the tank stuff uphill into the cleanout, as opposed to replumbing. A Flojet costs $300, and I have no clue how much it would cost to trench in a line just for a "sewer clean-out" near the RV.

or a sewer solution costs about $130?

If I can make this work, it would be a full hookup in my driveway where I store the trailer. Cable, phone, internet, 30amp, water.

Ok, The cap for the trailer will work for attaching a small hose.

I would rather have the trailer sanitary flexible hose connect to the DWV line though. This would all be gravity fed as the cleanout is +- 12" lower than the trailer pull valves.

does an adapter for the trailer hose to 2" or 3" abs exist?

Thank you for the suggestions.

You should be able to find an adaptor for just about any application at a plumbing supply store or in the local plumbing section of a home center.

At an RV supply you can get a sewer cap with a garden hose connector on it to fit your grey tank sewer connection, then run a garden hose from the RV to the clean out to dump your grey tank.
