Pluming Question...I need warm water.

At work we use warm water for mopping the floor. Currently that involves filling up a big stock pot with warm water and dumping it into the mop bucket a few times. What I’d like to do is just have a spigot (sillcock) at about mop bucket height so we can just put the bucket under it and turn it on. We used to have something like this, but we took it out for various reasons when we put in a new sink and re-plumbed everything. I could easily just tap into the hot water supply and do this, but washing the floors with hot water not only wastes a lot of hot water but isn’t so good for the floor wax, so I like to come up with a way to plumb both the hot and cold side to come out of one spigot. The easy way would be to just bring the hot and cold pipes to a T and have the spigot come off of that…of course that would mean warm water would come out of the faucets as well. So, what I’m wondering is if there’s a check valves I can sweat in-line and then connect the hot and cold after the check valves and bring that to a spigot, or if there’s some sort of all-in-one piece designed for an application like this.
Any ideas? I’ll take a look around Home Depot next time I’m there, I’ll check the Grainger catalog as well, but since it’s 11:30 at night, I’m not going to do that right now, so I figured I’d get a head start on it.

I hope you figure it out. It would really be a feather in your cap.

That was easy, and it works up to 3000psi to boot.
I’ll pick up two of these, plumb them to a T and then to a spigot.
Unless anyone has a better idea or some type of all in one thing, I think this’ll do it.

That check valve is for refrigerant, not water. They don’t specify a forward flow PSI, but anything that can hold back 3000 PSI might not flow anything at 45-60 PSI or whatever your domestic water is running at.

If you can easily tap the hot water line, can’t you also easily tap the cold line and just run both to a proper mixing faucet?

look for something like, similar from a few places

American Standard
Wall Mount Rough Service Sink Faucet with a Vacuum Breaker in Chrome

Model 8344.112.004

it is a wall mounted mixing faucet for above a utility sink, you can mount it where you need it. you might need a floor drain according to building code if not placed above a sink.

if you had hot and cold hose bib faucets (outdoor sillcock types) you can hook to a hose splitter backwards to mix the flows.

if you want or need check valves for water line use check in the heating section, they are used for the water supply in hydronic heating systems.

there are also hot/cold side-by-side and hot/cold mixing outdoor sillcocks that might work too.

What about just running a short hose from the faucet you’re currently using?

Whoops, didn’t notice that. Thought 3000psi was a bit high for water usage.

This is something that I’d like more or less permanently mounted. If every time they want to fill the mop bucket they have to hook up a hose, they’ll just use the stock pot.
Also, for everyone that suggested a faucet I’m staying away from that idea for two reasons. 1)It’ll be too big and bulky for where I need to put it, one of the reasons I want a spigot is because there’s a good chance we’ll just hook a small garden hose* up to it and use that for filling the bucket, it’s also helpful when you just need to hose the floor off and 2)I’d like this spigot to only dispense warm water, giving them the option means that they’ll just use hot water because they think that’ll work better the more idiot proof I can make this, the better.

*The sinks get used regularly throughout the day for everything else. The original setup had a hose attached to a spigot coming out from behind/under the sink. Pull the hose out, fill bucket, toss hose back under sink, worked great. I want to do that again, but I’m hoping for warm water.

you can get in-line mixing values and run that to a single sillcock faucet. you could also use in-line separate valves into a T and have a single sillcock faucet. you set the other valves at the right mix and people just use the single sillcock dispensing valve.

What about one of those standard temperature-control shower valves, like this one.

You could plumb the output into whatever sort of fixture you wanted (hose hook-up or whatever), and you would get the bonus of being able to choose cold or hot in addition to warm. (And you’d learn in one day where the perfect “warm” setting was on the dial for the mopping task.)

ETA: just noticed that you actually don’t want the hot water option available.

I guess I don’t understand. Why do you need a check valve.? That’s just a backflow preventer.

I would tee in to the hot, tee into the cold, add ball valves to each line. Then combine those with a tee, a there’s you spigot. Gonna need some ell’s of course

eta - Well my stick figure works before posting…I guess it’s the kern of the space.
