Flushing Tank Question

Picked up my new Georgetown 2011 378 last week and have a question on tank flushing procedure. After hookup to sewer I flush Black Water First, close valve, flush grey water, close valve. Then I attach hose to flush connection. Here is where I am a little lost. How long do I run this flush and do I just open the black water valve. Is this correct or is there a better way?

Jim

Start by getting one of these, Amazon.com: Valterra T1023 90 Clearview Adapter: Industrial & Scientific or Amazon.com: Valterra T1026-1 45 Clearview Adapter with 3" Bay Lug: Industrial & Scientific



and you will know exactly for how long to flush the black tank. And yes only the black tank valve needs to be open.

Frank is right on. After using the clear elbow with our camper, I see why I was always in the penalty box for dumping the black tank when we used to rent a TT before we bought.

Without that adapter you don't even know if it is actually empty or if you have a blockage that is preventing a full dump. The idiot lights are NO HELP since they can indicate "full" for a LONG TIME after you dumped due to crud on the tank walls.

Always dump from Black FIRST (then turbo flush till it runs clear); THEN dump gray water. That way you get to flush out your hose with soapy water before you put it away.

Thanks for the tips, I was not sure if Black tank should be open when flushing.

There is a big warning in the manual and several threads here about why it needs to be open during turbo flushing.

HI Folks

Thanks for these hints. I followed the advice, bought a clear adapter and flushed with no problems.

my black tank flush seems blocked

Has anyone else had a problem with the tank flush just backing up with pressure? Mine seems to be blocked with something, can only imagine what, and am not sure how to clean it.
Does anyone have any good suggestions of what to use to clean out the tanks?

Just about everyone here has had good luck using a product called RV-Digest-it made by Unique. RV-Digest-It.com - RV-Digest-It

I carry a quart with me at all times. Fill tank with water and a full quart; then wait 24-48 hours and a full dump. Repeat if needed.

Regular use of 2 capfuls of Liquid Calgon; a couple of gallons of flush water; and 2 capfuls of laundry detergent AFTER every dump will keep this from happening again.

I assume you are talking about the tank flush that you hook your water hose to. Is there any water going into the tank...the tank flushes on the Georgetown's do pressurize and spit back at you when you disconnect the hose..Is this what you are talking about????

Lou, could you please give a little more detail. I like the sound of the RV Digest as it is environmentally friendly. So:

Do you use this product, RV Digest, as your regular tank usage treatment? Add a quart every time after black tank dump? Or just for when the system blocks/clogs up?

2 capfulls of Liquid Calgon and 2 capfulls of liquid laundry detergent. This is to prevent what? Smell? Blocks/clogs?

I buy the packages of the little plastic blue product that treats the sewage holding. Are you saying not to use these. Use the above methods? Thanks.
