And DON'T keep the valve to your blank tank open while at the campground thinking "stuff" will roll right through. Dried up tank in the summer full of "stuff" won't make for a pleasent experience

I never have a stinky camper because I forgot
I would use more than I gallon. The pipes on the way to the shut off valve take almost a gallon depending on your trailer.

We've never had any issues with our black tank (like the dreaded clog) and follow a few rules:

- Thick rubber gloves that come almost up to my elbow whenever handling the sewer lines.
- Using an old hose to stick into the toilet to fill it or rinse it. (Never use your drinking water hose)
- Never messing with the black tank at dumping stations. Always quick in and out as people are waiting.
- Never dumping the black tank unless it's almost full and NEVER leaving the valve opened when parked at a full-hookup. If we need to bug out and it's not full, we'll start the night prior by doing long flushings to get it filled up.
-After dumping it, put about a gallon in there with some disinfectant or detergent. (Simple Green is cheap and smells great.)
- When dumping, always dump the black tank first than the gray to flush out the line.

I always keep a package of baby wipes in my truck to clean up after doing just about anything...setup/teardown/sewer management.

As some others have stated the Rhino hose is the way to go. I debated on if it was worth the higher price when we bought our 5er. Would not have anything else now. Ours was a kit with 2 10' hoses, the elbow and caps for the hoses. Have since bought the clear 45 elbow.

Strongly reccomend Thetford aqua-kem liquid. You can get 6 bottles (8oz) at Walmart very inexpensively. I pour a bottle in after each dump and flush a few times. This is the only stuff that cleans the sensors (which everyone says are a bad design) so the tank indicators actually show empty. I also agree with all who mentioned the clear elbow so you can check on the flow

Always drain your black tank then your grey, that way the gray water flushes out the hose. Double check on the black tank flush, most of the new RV' have them. That is something that will help flush out the black tank. The flush king is great for breaking a plug at the valve. If the pipe doesn't go directing into the tank (travel trailer), but up (motor home and/or 5th wheel) you'll need the flush king with the extra valve on it.

Good luck

X2 on the Rhinoflex - buy NOTHING else. Cheap sewer hoses are a disaster waiting to happen

Check and make sure you do not have a water hookup for a black tank rinse.

a Great chemical system for black tanks is made by

Finally, remember to NEVER keep the black tank valve open! Keep it closed until it's time to leave or the tank is over 3/4 full. Then dump black, rinse black, flush hose with gray tank water.

I put a gal. of water in both gray and black tanks after dumping. This way any debris left behind won't get a chance to harden and be very difficult to remove.

I like the variety at Camping World, but they don't always have the best prices. Sooner or later you will learn that Wal-Marts across the nation have a section reserved just for RVers. They carry Camco, Dometic and other familiar names for a lot less than you could get elsewhere. Here is my black water story: (everybody has one) I told the family we had a limited amount of water in our holding tank, so flush the toilet with the minimum amount of water...BIG MISTAKE! What we ended up creating looked like one of the great pyramids. Thankfully, another camper told us a quick solution: at the first opportunity, dump in a 25 pound bag of ice, then resume driving. The back-and-forth action will help loosen the mess. And, be sure to use a good chemical additive after every black water dump and every few days if you don't dump.
