Finding a Watts 3-Way Fresh Water Valve

[zulutron]

Where can I get a replacement for this fresh water valve which is used to send incoming water to either the water tank or to the inside plumbing:

3-Way Water Valve - 5021846

It's called a 3-way valve and is available wherever plumbing fixtures are sold. Very common in RVs and marine use, so places like etrailer.com, West Marine, RVUpgrades.com, RecPro, etc have them. Also supply outlets such as Grainger Industrial. Even Amazon and Walmart.com! It's a commodity so Watts is just a brand name (a good one!) and there are a dozen others.

You do not need that brand many others will work as well.

I want a Watts because of quality and fit. Some of the 3-ways I looked at won't "fit" (screw holes) and some aren't suitable for potable water.

There's no spec on this cheap valve. Is it suitable for potable water?

True, they are very common, but it's been very difficult finding a 3-way valve spec'd for potable water. It should be lead-free and meets NSF 61 and 372.

For example, like this guy I just found:

Valworx 3-way

Valworx 3-way spec

NSF 61 certification

NSF 372 certification

OK, your call, but all brass, lead-free valves for potable water are available. They are more expensive, though.

I don't see the Watts brand 3-way (diverter) valve on Amazon, but plumbing supply houses have them if you are willing to pay their prices. Here is a 1/2", NPT-threaded model. Watts also makes 3/4" threaded and "sweated" (soldered) types.

Thanks, but I'll probably go with the Valworx it's half the cost plus Valworx lists all certs and then some.
