An RV Dump Station with Two Faucets
If an RV dump station has two water faucets, one will be for drinking, the other will be for rinsing. If it only has one faucet, it is meant for rinsing only. However, there is more to this. Read on…
RV Dump Station with Only One Faucet
RV dump stations with one faucet are painted red is because they know people will use them for rinsing out their black tanks, and end up touching the handle and threads with unsanitary hands. Owners are not willing to accept liability should someone get sick from drinking the water.

Basic Clean Drinking Water Equipment
If you’re new to RVing, there are a few basic items you’re going to need. The first are drinking water hoses. RV fresh water hoses are either white or blue. You might be tempted to save a few bucks by using extra hoses you may have around, but don’t. Just…don’t. Here’s why.
Getting Your Drinking Water System Clean
It’s just not possible to get clean water out of dirty plumbing. So the first step in your journey toward drinking your RV’s water is to get your water system clean, and free of any contaminants.
Inline Hose Filters
These are the ubiquitous small, disposable cartridge filters that you hook up directly to your freshwater hose for filling your tank or hooking up to city water. These are really the “entry-level” RV water filters. Right now, there are two kinds of them readily available: Blue and Green. The two kinds have differences besides just the color.
Other Portable Water Filters
A quick search will turn up lots of options for portable RV water filters. The one pictured here, the Clearsource Ultra, is the one we’re traveling with now. We use it outside the RV to filter water on the way in. We’ve taken to calling it “The Beast” for obvious reasons. This is what we use when we’re serious about filtering the water.
Permanently Installed Filters
It’s also possible to install a water filter in your RV so that it’s just there all the time. This has the advantage that you’ll never have to remember to hook it up. Many of the permanently installed filters look and function the same as the portable ones.
Other Clean Water Technologies
Besides filters, there are other technologies to satisfy the three water criteria of clean, tasty, and safe. In our home, we have a reverse osmosis (RO) system.

Make sure to pick some up before going on a trip where you know you’ll have to harvest water from a questionable source, no matter what kind of filtration system your RV has.
