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?

Not the same. The washing machine isn't dumping all 40 gals at once but only a percentage of the 40 gals over a period of 30-60 minutes. A washing machine will only dump 5-7 gal at a time at the end of each cycle.
A septic tank water level will be equal to the bottom of exit port in the tank and below the inlet port.
Overflowing a septic tank one time is not likely to damage the leach field. It's the accumulated effect over a period of time that causes the damage.

The outlet baffle prevents the floating scum layer from entering the outlet when the water level rises as waste enters the baffled inlet. All that happens with a larger influx of waste water is the scum layer rises a couple of inches higher on the baffle briefly as the water moves into the leach field, dry well, transpiration mound, etc.

Just be careful of putting it all in at one time. there can be a he!! of a big burp and you will have a mess and a half on the hose side. Ask me how I know.

Dosing a septic tank with large quantities of water is good for the drain field, Google it. They make dosing tanks specifically for that purpose.

OP--If you have a septic field, this is what you need to know! Find out what you have.

A septic tank vents back through the roof vent(s) in a house. With no house, you may need a vent pipe directly from the septic tank which would be added by breaking into the inlet pipe to the tank. Might only need to be 2-3' above grade and would have a couple of 90 degree elbows together to make a 180 degree inverted bend along with a P-trap sort of like in the right side of the photo. Should have a cleanout at the inlet to the tank.

I have been living in a home with a septic tank/field for almost 60 years. When your 1000gal tank is filled with liquid and starts to leach into the drain field tiles, any new liquid (and its' contents) will cause an equal amount of liquid to go from the tank into the drain field. When you empty your RV tanks it is more than a drop in the sea! 50 gallons in equals 50 gallons out! :E This many be more than your drain field can handle at one time.

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?


well my SIL overflowed hers by running too many laundry loads thru in too short a time.

Either dump frequently (1/2 tank) or use a macerator pump if you are worried about overloading the system.. at 6 GPM a macerator should not overload it.

Plus it breaks up some stuff.
