Washing Machine to mixed water hose?

[NitroPress]

(Okay, neither heating nor AC, but not electrical or general, either... mods free to move this topic elsewhere.)

I have a standard washer/dryer closet right next to a rear sliding door. For six years, I have scratched my head and tried to figure out how to run a mixed-temp hose outside for things like dog washing. (My big-picture plan was to replace the side-by-side units with a stack, then put in a very useful utility sink, and voilá... but that's for another day.)

So I have copper sticking out about three inches, soldered valves, and hoses to the washer. I have gone through every combination of plumbing and garden hose adapter and fitting to come up with something simple, either permanent or quick-swap, that would let me hook up a garden hose and mix the temp... all without endless leak points and hopefully without doing new soldering, as I seem to have lost my touch with copper plumbing.

Anyone have a simple idea for giving me this dual-purpose water connection, using more or less off the shelf parts? I don't mind if it takes a minute or two to swap out, as I really only need a warm-water hose about four times a year, during the colder months when the ground water hose is too cold for the dogs.

Ad(thanks)vance!

This with the right supply hoses. Dishwasher hoses should work as they go from 3/8 to 3/4

Personally, I would plumb in a thermostatic mixing valve. It will allow you to set a temp and not have to mess with it. I used one for the hot feed on my kids tub in my last house so I didn't have to worry about them accidentally making it way too hot when they were starting to do showers on their own

I installed one of these Woodford's at my house. Initially it sucked, but then I raised my well pump pressure settings and works fine now. They also have side-by-side vs vertical.

You might want to consider brushing up on your soldering skills and using a Moen Posatemp (SP?) mixing valve.

Thanks for all so far. The need for something like a temp-balancing valve isn't there — this is for infrequent use where manually monitoring the temp is no hassle. (I've lived with oil fired heat/water systems where the temp valve was a critical component — I understand their role.)

I'm mostly seeing if anyone has an idea about how to hook up this temp-mixing valve so I can easily connect the hose when needed, without a lot of plumbing work, and again with minimum chance of leaks. Looking for combinations of common or oddball hardware that might connect A (standard washer hookups) to B (two valves and a hose connection).

I dunno what to say about my copper skills. Did hundreds of joints over the years, often as fast as a pro, and for some reason I can't get a simple slip connector to seal any more.

I'd love to put one of these in with permanent plumbing, to have an outdoor mixed temp spigot. Just not quite arsed to do such major projects any more, not for this house, any way.

Something like this garden hose Y



connected backwards. Use it to connect to your washing machine valve outlets. Rework a hose to have two male ends. You’ll have to mess with the ball valves to get the desired water temperature, but that shouldn‘t be difficult.

Using some combination of Y splitters was my best idea. It's actually fabricating that two-input hose that's kind of a bear — my thought was two short F-F hoses and another Y splitter, which would then need a M-M hose to connect to a spray handle. Gets... super messy fast.

I guess a barbed T would work to connect a second M end to a hose, too. And once there, quick-change fittings might be better (over two permanent Y's) to swap the washer and hose connections... but sooooo many leak points over time.

Sigh. I hate this stuff in the middle, a little too complicated to do Rube Goldberg style, and a little too low-need to actually reconfigure plumbing. Besides, that cool dual-feed Woodford valve is ~$200...

I have a "warm water" bib in the shop. It was originally used to raise the incoming water temp for our RV so you could get a decent shower with a 6 gallon water heater in the winter.. But at the end of the day, all it is a single brass handled valve where I control the flow of cold water into the mix on the hot water side and that works well enough. A mixing valve would be more consistent if you're moving it around. I did it with PEX left overs (I do have a crimp tool). In your case, I'd just add two flexible connections at the washer bibs.

Nobody has suggested the easiest solution. Just get a washer Y hose. Amazon has them for $12 and that lets you mix hot and cold for exact temp you need and then hook to a single hose. Problem solved.

I have washed many a horse with a hot and a cold outdoor spigot and a wye hose. I often pondered how well a toilet mixing valve (tempering valve?) would work, would it flow enough?
