Hi from virginia!

My fiancé and I just bought a 2015 Rockwood HW296 last week. We are excited to take our first trip with it but we have never had a camper that required us to use hookups. Any tips on emptying and maintaining the black and grey tanks is much appreciated!

Welcome to the Forums from Huntsville AL Harpbone!

Do a forum search on sewers and you will learn more than you ever thought you would need to know on sewers

Your first purchase MUST be this: Camco 39761 RhinoFLEX 15' Sewer Hose Kit with Swivel Fitting: Automotive

If you were given a sewer hose just toss it. You want peace of mind and a Rhinoflex will give you that.

If you have trouble finding sewer info, PM me and I will help you out

Hello from Ohio. If using full hook up, keep valves closed til ready to dump, dump black first, then grey. Oh, keep an eye on the grey tank gage, you don't want to have to dump it in the middle of a shower, when it's chilly, when you have lots of shampoo still in your hair.

I use Black Tank Chemicals. I let the Black tank fill to almost full. I dump the Black tank first then shut off Black tank then open the Galley tank then open the other gray tank that is for the Bath wash water. I also have a Black tank flush system.

When flushing your Grey and Black tanks. Flush your black tanks first empty. When empty, lift the drain hose several inches. Open the gray tank and back flush into the black tank. the soapy water from the sink will clean out the tank. When the water levels are even (you will have more 'grey water' that black water), close the grey tank (still half full) and let the hose down and empty the black tank. repeat once more, lift hose slightly and open grey tank handle and flush back into black tank, when 'even' let the hose down and let both tanks empty. You will now have a fairly clean black tank. Also, only use 'approved' (that works) paper for the bath stool that dissolves.

Welcome from the middle of the US.

You've gotten a good deal of great advice here, and that is one of the best things about this forum - other than the people we've met both on line and in person.

Here's one more "be sure"...before you remove the cap to attach the hose to the dump valve, BE SURE both the black and grey valves are CLOSED!

And then, just go out and

Welcome to the forum, you now have access to tons of info from people who use the systems. You can have all your questions answered here in detail. The best PDI around. I am new to camping also this site has been a lot of help. On my first trip everything worked great just like they said it would. Have fun and enjoy.
