Camco 20123 Brass Y Valve, Fresh Water Hose Shut-Off
Camco 20123 Brass Y Valve, Fresh Water Hose Shut-Off — Product description
The Camco 20123 is a solid brass Y valve that splits a single fresh water hose into two lines, each with its own quarter-turn shut-off. Hook up your dock or campsite water and a wash-down hose at the same time, and shut either one off without unscrewing anything. Low-lead brass and stainless steel valves keep it safe for drinking water.
If you've ever had one garden hose running to your RV or boat and needed a second line for washing down or topping off a tank, you know the dance. Unscrew one hose, screw on the other, then swap them back. The Camco 20123 brass Y valve ends that. It threads onto a single water source and splits it into two separate outlets, each with its own shut-off. Run two hoses at once, or shut either side down without touching the other.
This one's built to last. The body is solid brass, not plastic, so it shrugs off the knocks and line pressure that crack cheaper splitters right at the threads. Each outlet gets a stainless steel quarter-turn valve that's pressure seated, which means it actually seals tighter the more water pressure pushes against it. The handles are easy-grip, so you can work them with wet hands or in cold weather without fighting a thin plastic lever. A quarter turn is all it takes. Full open to full closed, no multiple twists and no guessing.
Because this valve is made for fresh water, the brass is low-lead. It meets California and Vermont regulations for brass content, which are the strictest lead rules in the country for anything that touches drinking water. So if you're filling a potable water tank or running a line you'll actually drink from, this is the right kind of valve for the job. Not every splitter can say that. The packaging is printed in both English and French.
Where does it earn its keep? At a campsite, thread it onto the spigot and run one line to your RV's city water inlet and the other to a hose you keep for rinsing gear or filling a portable tank. On a boat, tie it into your dock water supply and keep a wash-down hose live on the second outlet, ready whenever you come back from a day on the water. First-time RV owners like it because it takes the guesswork out of splitting a water source. And anyone who's spent a weekend swapping hoses back and forth will get why it's worth keeping one in the bay.
Using it is about as simple as gear gets. Screw the inlet onto your source, screw a hose onto each outlet, and open or close each side with its own handle. Want water going to only one hose? Close the other. There's no need to disconnect anything or shut down the whole supply. That's the whole point of a Y valve, and this one does it without drama. If your source runs high pressure, it's still smart to put a pressure regulator ahead of the valve to protect your hoses and your RV or boat plumbing, the same as you would with any fresh water hookup.
When the season winds down, take a minute with it. Disconnect it, open both valves, and let it drain fully before you store it. Water left sitting inside any valve can freeze and split the body, and while brass handles cold far better than plastic, it's still smart to get the water out. A little silicone grease on the threads and the valve stems once a year keeps everything turning smooth and the connections sealing clean.
A couple of honest notes. This is the valve only. Hoses aren't included, and you'll want good quality drinking-water-safe hose on both sides to keep the whole run potable. It's built for fresh water fill and supply duty, not for high-pressure industrial plumbing. But for the vast majority of RV and marine fresh water setups, it's exactly the kind of simple, solid part that just works and keeps on working season after season. That's the Camco reputation, and this little brass Y valve lives up to it.

Frequently asked questions
What does the Camco 20123 Y valve do?
It threads onto a single fresh water source and splits it into two separate outlets, each with its own shut-off. That lets you run two hoses at once, like a line to your RV or boat and a second wash-down hose, and shut either one off without disconnecting anything.
Is it safe for drinking water?
Yes. The valve is made from low-lead brass that meets California and Vermont regulations for brass content, the strictest lead standards for parts that touch drinking water. It's built for fresh water fill and supply duty. Use drinking-water-safe hose on both sides to keep the whole line potable.
What are the shut-off valves and handles made of?
The housing is solid brass, and each outlet has a non-corrosive stainless steel quarter-turn shut-off valve. The handles are an easy-grip design so you can work them with wet hands or in cold weather.
Can I shut off one hose without affecting the other?
Yes, that's the main reason to use a Y valve. Each outlet has its own handle, so you can close one side and leave the other running. No need to shut down the whole supply or unscrew a hose.
Does it fit a standard garden or RV water hose?
It uses standard hose-thread connections, so it works with common RV and marine fresh water hoses. Thread the inlet onto your spigot or dock water source and screw a hose onto each outlet.
How do the valves operate?
Each side is a quarter-turn valve. A single quarter turn of the handle takes you from full open to full closed, no multiple twists. The valves are pressure seated, so they seal tighter as water pressure pushes against them.
Does it come with hoses?
No. This is the brass Y valve only. Hoses are sold separately, and we'd suggest good quality drinking-water-safe hose on both outlets.
What does complying with CA and VT regulations for brass content mean?
California and Vermont have the country's strictest limits on how much lead can be in brass that contacts drinking water. This valve is made from low-lead brass that meets those limits, which is why it's suitable for potable fresh water use.
Can I leave it connected in freezing weather?
It's best not to. Before freezing temperatures or winter storage, disconnect the valve, open both sides, and let it drain fully. Water trapped inside any valve can freeze and damage it. Brass handles cold better than plastic, but draining it is still the safe move.
Can I use it on a boat as well as an RV?
Yes. It works anywhere you have a fresh water supply to split, whether that's a campsite spigot, an RV city-water connection, or dock water at your slip for a boat wash-down line.
