You don't need to buy a drum, just dig the hole as deep as you can and put rocks, then gravel, then 6 inches of soil on top. Putting a perforated PVC pipe down the middle helps, but is not essential. It's called a "dry well" if you want to research options.

Since you didn't put put any infomation in your signature about what type and model Ethyl is this may not apply.

Some RV's have more than one grey tank and I've seen people (myself included) forget to drain the second tank.

I did indeed figure out why the gray tank filled so quickly, it appears that rain water had somehow gotten in thru the plug in top of the RV that my son-in-law left open *grumble*. Hooked up the drain hose, dug a hole and no the tub is emplty, no smell and I have my gray tank safely draining into a *french* drain ( the 55 gal drum buried with holes punched into the bottom and sides.)
How well over $100 for the blue boys? And what kind of septic company? I put some RV digest-it in the black tank to help but I have no idea how much or often it was used before I bought Ethyl. Also, the gray water tank was used before I got her. She and I are learning each other =)
I plan to eventually get the LP gas hot water heater hooked up/filled so I will be totally self-contained. Haven't figured out how a lot of the stuff in here works yet but I'm getting there. Thanks for all your help.

I think I added a signature. Ethyl is a 1986 Holiday Rambler Class A Imperial and that's about all I can tell you about her. I don't think she has a secondary gray tank according to the owner's manual but I could be wrong.

I need a little more information about Ethel. Does she have the bathroom in the back or in the middle? Twin beds or queen? Dinette or wardrobe?
I have a 1984 Holiday Rambler Imperial. It has the middle bathroom which required the grey tank to be separated from the black tank. There are separate dump valves on either side of the rear tires. Makes dumping a little awkward and extra work.
If you have a rear bathroom, it is an entirely different arrangement.

WHAT plug???

Never heard of a "plug" in the top of an RV.

If you are talking about the gray water VENT pipe, this must NOT be plugged, or you will force truly noxious vapors into your rig.

Unless Ethel has a concave roof, I can't imagine enough rain getting in a vent to fill a tank. As I said in my earlier post, I believe you might have a tank flush fitting with an open valve that filled the tank when you filled the fresh water tank.

I found the PO had rigged up such a plumbing situation in my rig. He had put a Y hose fitting on the hose bib from the FW tank, back flow preventers, then hoses to flush fittings on each waste tank. I disconnected the hoses and capped them, I just didn't like a physical connection between FW and waste, even with a back flow preventer.

Yup, your gray tank is full and backs up through lowest the P trap first. usually shower or tub. Dont depend on your tank gauges to be accurate.
