We have an areobic septic at home. We are shopping for a 5'er or TT now. Is it OK to dump the blackwater in the septic when it has the chemicals mixed in there?

I'm not sure what an "Aoerobic" septic system is?

When we built our house 4 yrs. ago, our system is called a "sand Filter", has a drain field plus an intricate sand filter waste is sent through. I put a drain access on both sides of my driveway, connected to the system and have no problems whatsoever. We cleared it with the installer, said would have no effect on system.

The Areobic type is the one with the air pump and sprinklers.

Welcome charliez, if your sprinklers are for the "water" in the septic, I would think you need to make sure you have enough water, (not black tank water) in the system. I would read the contents of your chemical first to make sure. Good luck

I live out in the country and also have a septic system. Mine is an older design base on 2 fields that work on drain and evaporate. I switch between the fields every month via a "bull valve".

I use to dump my class C in mine all the time as I could drive it up close enough to dump via and "inspection" tap. Now that I have a 37' class A I can't do that any more.

I dont' use any chemicals in my system as they are not in the "holding tank" long enough to do any good. If you use LOTS OF WATER and clean your tanks you will not have any problems.

I clean my tanks with DISH WASHER Powder and CALGON Water Softener Powder. I mix a cup each or so in a 5 gals of warm water and dump in a 1/3 full holding tank, drive to the camp ground/RV park and dump as soon as I get level. I have no odors and my sensors work.

Also consider the volume of your Rv tank versus the volume of the septic system. Dumping 40-50 gallons of black water into a small septic system can be quite a shock and might overwhelm it. Older systems may be quite small, designed for max of 300-500 gallons of waste capacity. But if your system is geared for a 1000 gallons or more of waste processing, dumping in another 50 gal is probably not a big thing.

We have dumped into both an aerobic system and a leach field systems and never experienced any problems. Generally bout the most we have dumped in was about 35 or 40 gallons of black and about the same amount of grey. We use the Potty-Tabs in our black tank. Fellow that put in our aerobic system said it would be OK as seldom as we were doing it.

Stop and think how many gallons of water you dump in there when you you empty one on the huge "garden tubs". Got to be closer to 100 gallons.

I suggest you check with your local authorities. I say that as in Minnesota they changed it so that you must have a seperate system or holding tank for the RV. The reasoning is that the house system is designed for a cartain amount of waste volume per day. Dumping the tanks of a RV all at once normaly exceeds the capacity the system is designed to handle.
