The number one question most seasoned RVers get from newbies is almost always about the sewer or ‘black water’. It really isn’t a big deal IF you know what you’re doing! There are some very specific steps to take to make this necessary part of RV camping painless.
How-to Empty the Black Water Tank
5 Simple Steps
Get GlovesSome people get a box of disposable gloves and use a new pair every time they clean out the black water line. I actually recommend a pair of heavy-duty plastic gloves like you’d wear to do dishes. You can find them specifically made for RVers too. Make sure they are the ones that go up your arm a bit too. These are easy to wear, flexible, and clean off easily.
Start with the Black WaterBefore you pull any valves, make sure all your connections are very tight on both ends of the hoses. Then, gently pull just the black water tank valve open. You’ll hear a swishing sound. That’s is the waste from your toilet moving through the hose.
Empty the Gray Water SecondOnce the swishing sound of the black water line ends, gently pull the grey water valve open. This is the wastewater from your shower and sinks. In addition to getting rid of that wastewater it’s also cleaning out the hose – that’s why you run the gray water AFTER the black water.
Shut the ValvesOnce all the tanks are completely cleaned out, you’ll want to shut the Black Water valve first and then the Grey Water valve.
Hose Down the HoseSome RVs come equipped with a flushing system that will flush out the sewer line. If you don’t have that, just take a regular hose and wash down the sewer hose if you think it needs it. Leave your sewer hose connected the entire time you’re at the campground, keep your eye on the tanks’ gauges inside the RV, and when in doubt, flush your tanks daily.
