Camco RhinoFLEX 22990 25-Ft RV Tank Flush Hose
Camco RhinoFLEX 22990 25-Ft RV Tank Flush Hose — Product description
The Camco RhinoFLEX 25-foot tank flush hose is the orange PVC hose you keep with your sewer gear for rinsing black, gray, and tote holding tanks. Standard garden hose threads on each end connect it to your water spigot and your tank's flush inlet, and the bright orange color keeps it from ever getting mixed up with your drinking water hose.
Every RV owner learns the same lesson at the dump station. You want a dedicated hose for rinsing your tanks, and you never want it anywhere near the hose you drink from. That's exactly the job the Camco RhinoFLEX 22990 is built for. It's a 25-foot orange PVC hose made to flush out black water and gray water holding tanks, plus portable tote tanks, so you can clean up properly after every dump.
The bright orange color is the whole point, honestly. It means nobody on your crew is going to grab this by mistake and hook it up to the fresh water fill. Keep it coiled with your sewer hose, your gloves, and the rest of your dirty-side gear, well away from your white or blue potable hose, and you've got a simple, no-guessing system. This one is for waste-tank rinsing only. It's not a drinking water hose, and it shouldn't ever be used as one.
Both ends carry standard garden hose threads, so hooking it up is about as easy as it gets. Screw one end onto your water source and the other onto your RV's built-in tank flush inlet, if your rig has one, or onto a tote tank's rinse fitting. Because it threads like a garden hose, it also works with any standard garden-hose-thread connection you already run, and it fits right into the rest of the Camco RhinoFLEX system.
The 25-foot length matters more than you'd think. It gives you room to reach the water spigot from most sites without repositioning the rig, which is a real help when you're backed into a tight spot and the water hookup sits off to one side. You get to leave the camper where it is and still run clean water to the tank, and that alone saves you the headache of unhitching just to line things up.
PVC construction keeps the hose light and easy to coil, and it stands up to the everyday abuse of a dump station. Drag it across gravel, leave it in the sun between rinses, roll it up while it's still wet. It takes all of that in stride. There's nothing fussy here, just a straightforward tool that does one job and does it well.
So who's this for? Anybody who dumps their own tanks and wants the job done right. First-time RV owners putting together a proper sewer kit for the first time. Weekend campers who only dump now and then. Full-timers who are at the dump station every few days and want gear that keeps up. Even boat owners running portable waste totes will get good use out of it. If you rinse holding tanks at all, you want a dedicated hose for the task, and the orange keeps everything honest.
A quick word on getting the most out of it. After each rinse, run clean water through the hose, drain it, and let it dry if you can before you coil it up. Store it separate from your fresh water equipment so there's never any chance of cross-contamination. Treat it like the dirty-side tool it is, and it'll give you season after season of service. Rinsing your black tank after a dump helps break up solids and keeps odors down, and a gray-tank rinse clears out grease and soap residue, so a good flush hose earns its keep fast.
It's a small piece of equipment in the grand scheme of an RV setup. But it's the kind of thing that quietly makes tank maintenance faster, cleaner, and a whole lot less unpleasant. Pair it with your sewer hose kit and a pair of disposable gloves and you've got the dump station handled, trip after trip.

Frequently asked questions
What is the Camco RhinoFLEX 22990 hose used for?
It's a dedicated hose for flushing and rinsing RV black water and gray water holding tanks, as well as portable tote tanks. You connect it to your water source to clean tanks out after a dump.
How long is the hose?
It's 25 feet long, which gives you enough reach to hit the water spigot from most campsites without repositioning your rig.
Why is the hose orange?
The bright orange color is a safety cue. It keeps you and your crew from confusing this waste-tank rinse hose with your fresh drinking water hose, which is typically white or blue.
Does it fit a standard garden hose connection?
Yes. Both ends use standard garden hose threads, so it screws onto a normal water spigot and onto a tank flush inlet or tote tank fitting.
Can I use this hose for drinking water?
No. This is a non-potable hose meant only for rinsing waste holding tanks. Keep it completely separate from any hose you use for fresh or drinking water.
What is the hose made of?
It's made of PVC, which keeps it light, easy to coil, and able to handle the everyday wear of dump-station use.
Can it flush a portable tote tank?
Yes. It's designed to rinse black and gray holding tanks along with portable tote tanks, so it covers the tanks most RVers deal with.
Will it connect to my RV's built-in tank flush inlet?
If your RV has a built-in tank flush fitting with standard garden hose threads, this hose threads right onto it. Check your rig's inlet to confirm the threads match.
How should I store the hose?
Rinse it out after each use, drain it, and let it dry if you can before coiling it. Store it with your sewer gear and away from your fresh water equipment.
Is this part of the RhinoFLEX line?
Yes, it's part of the Camco RhinoFLEX family and works alongside the rest of the line and any standard garden-hose-thread fitting you already use.
