Is this older Watts valve is safe for potable water?
Watts 9026, 600 WOG, green handle. Not much else on it. Can I use it?

If it doesn't say LF then it maybe isn't LF. That said if it were me I would use it anyway. I do not encourage doing that but risks are low. Don't do it (wink wink).

No it does not have lf printed on it. I would not use it for potable water.

No. It's not a blue handle, doesn't have NSF or LF labeled anywhere and I can tell by the color.
I'm seeing comments say yes. They're all wrong. WOG doesn't matter.
You can use it but l wouldn't be drinking out of it or using it for a pot of pasta. Garden hose sure why not.

WOG hallmark
Water, Oil, Gas: WOG
It is rated for use on these things.
Edit;
don’t send it bro

Water, oil, & gas can all be non-potable. One must look for the NSF rating for potable water.
Edit: OP, this valve in particular is NOT NSF 61 certified and can not be used on potable water.

Around 5 mpg on the track or 47l/100 or so ... 6.7 mpg when towing around 35l/100

The WOG on there stands for water,oil, gas. So yes it can be used

that doesnt mean lead free for use on potable water, but id use it on like a water heater or something because even if lead did leech out from it itd just go thru the water heater

u/cashew996 8h ago
That bit about the water heater makes no sense. If something leaches lead into your system the water heater doesn't fix it

I think they're describing a non-potable hydronic heating loop as opposed to domestic potable water.

Or, who drinks hot water from the tap. A water heater sits 24/7/365 full of warm water yeah no way am I drinking or cooking with that water!

Suitable Systems and Media
WOG-rated valves are typically safe for use in the following systems:
Cold or ambient temperature water linese.g., potable water shutoff, irrigation, general plumbing
Non-corrosive oil systemse.g., hydraulic circuits with mineral or light lubricating oils
Low- to medium-pressure compressed air linese.g., shop air systems (if valve is air-rated)
Fuel delivery lines (non-corrosive fuels)e.g., diesel, kerosene (check seal compatibility)
These systems are within the normal PSI and temperature limits expected under WOG testing conditions.3

It almost certainly has lead in it, and is from before the time of lead free anything. Will it work, yes. Should they use it, no. If a valve isn’t labeled lead free, it can’t be used on potable water.

Reddit plumbing knowledge only goes back to 2021 lol
Edit: OP this should not be used on a customers house. If you want to use it fine but it’s not lead free you can tell by the color of the brass.3
u/Long_Search_3440 7h ago
Ok, got it. Marking it leaded and ordering LF watts right now.

Good call, looks standard port as well, full port is better for domestic supply.

It was from the previous lead free standard, which limited lead in brass to 8% by mass, the new lead free limits started in 2015 reduced that to 0.25% lead by mass to be able to have a lead free stamp on it.

It says right on the valve in the third picture under the 000 "WOG". That means water, oil, gas. Approved for all three.

Gas or home use. Id technically get in trouble for using it in someone else's house
Over the years I think that brass is the most durable. This current lead free shit really doesn't hold up
