Tapping into septic

[TinCanLand]

Aside from pulling off the lid and hanging the black water hose directly into the primary tank, does anyone have a fixture they have already cobbled together?

I have tried this, and, well, it stinks (literally!).

There is no room to access the main sewer line from the house to the primary tank, so going into the tank itself seems to be the way to go.

This is a LPP system, so cannot go into the secondary tank or the connector between them.

Appreciate any ideas. Thanks, Steve

Are we to assume that "no room to access" means that you cannot dig an interceptor line from your trailer location?

Get a pooper pumper and load that tank with a hose.

Is that concrete or metal in the picture?

Assuming the lid is concrete, I would hire a 4 inch diamond hole cutter to go with a powerful electric drill, cut a hole in the middle of the lid, and use some 4 inch domestic piping from the local hardware store to fabricate a suitable connection system with a cap. The joint between pipe and lid can be sealed gas-tight using spray foam such as "Really Great Stuff" from Home Depot.

If you get a sewer solutions system you would only have to cut a 1 inch hole, use 3/4 inch pvc and plumb the adapters with a hose fitting.

Surely there must be at least some clearance between the house and the tank. All you need is 12" or so to get a wye in there. Often the lines aren't especially deep so you can hand dig. Then you can run 4" PVC from there to wherever you want to park your trailer, with 1/8" to 1/4" drop per foot.

If there's no way to make that work you might be better off using a cleanout in your house somewhere.

In most cases all you really need to dump is greywater so you can get by with much smaller hose and pipe sizes.

You have got to have a sewer line "clean out" access between the outside of the house and the tank. Those are 4 inch fittings. Just plug in there.

Ditto, just make sure you use a tee with "sweep" fittings and don't spare the new cleanouts, with sweep fittings, also. 1/4" per foot drop will work fine, I've done it.

Thanks all for the ideas.

More I look at it, we may move the parking spot to a better location (more scenic!) and pump up hill a little bit.

Appreciate any experience/comments with the water jet and/or macerator equipment.

Thanks, Steve

All you need to know and yes it works as advertised. A couple years ago we would have weekly pump out parties here at the house. I had not one but four RV's needing to be pumped. We would break out an 8 pack of cold beverages and have the pumping out done before the beer ran out. FWIW it was fellow crew members working on a project. I had plenty of room and lived closer to the jobsite than the nearest campground.
