Hooking up to house sepitc

If your septic system is a holding tank and a dispersion field, I would make sure that what you have can handle the volume that you are going to introduce. It's not just the liquids that have to be dealt with. These systems are designed to deal with a flush at a time. Is there a pump or is it gravity......?

If you are connecting to a municipal sewer system, you should have no problems. You probably have a
4" PVC pipe with gravity flow to the main in the street. Find the end of the pipe and install a cleanout if you plan to extend it later. Make sure the pipe is capped upstream of the cleanout. If not, just install a 4" sweep (not an elbow) and extend it to the surface. Find an adaptor like you would see on an RV site and make sure it has a screw adaptor on top. Just hook up like you do at a camping site.

Ask your local RV site who their suppliers are........

The link below shows a typical arrangement from google. Or Google it yourself if the link scares you.

I'm curious if anyone has actually overflowed their septic system by dumping all at once? My holding tanks are 36 gallon which is about the same size as a standard bathtub. What would be the difference?

Am wondering if any one has done it. I have a piece of land (free parking!) and the house has been removed but a very new septic system is still there. Not sure how to pull it off like holding tank bypass,connections, parts, hoses needed?

You say the septic system for the old house is still intact? have your local Plumber come out and hook you up with a simple systems like the local state park has.

Easy enough...use your regular sewer hose and the clean out from the septic system.

As already posted, don't dump everything all your tanks all at once or you may, "over dose" the system. Dump some and then let it rest for a while and dump some more.

I am in process of doing just this same thing on some land we just purchased All I am doing is running a 4in line to side of slab & turning up , then putting on cap to seal while rv gone.
I all ready have a adjustable 3in pipe with rv connection on one end & a 3/4 rubber reducer coupling We use at our rented site at the lake.
You can just use your flex hose to hook up but long term will deteriorate quickly in the sun.i wouldn't worry about amount dumped at one time if you just using your land as occasional get away place as we will do

Lots of people have used home septic systems for dumping their trailers. My desert buddy even built his own septic system at home to dump his trailer even though he has city sewer hooked up to his house. Most put the regular trailer waste hose into a clean out in the yard.

The general consensus is to not release the black tank all at once as you could flood the septic vault and over flow the solids but other than that proceed as normal.
