I am a automotive detailer enthusiast. I have a heated three car garage and I spend a fair amount of time cleaning my truck.

Here in Cincinnati I still wash my truck in the winter. I want to put a spigot in the garage that during the winter I can have a 50/50 mix of cold and hot water and in the summer use the hose outside. I have to drill through 8 inches of concrete to gain access to my unfinished basement. Which is not a problem I have already drilled for compressed air and natural gas.

I found a dual stem spigot that will work for my needs but ideally I would only drill one hole, is there a way to mix the two in the basement by adding check valves in the lines so they mix prior to getting to the spigot and in the summer I could turn the hot water side off in the basement if I decide to use it instead of the hose?

Not sure if this is making it more complicated than it needs to be mg just drill two holes and call it a day?

You want something like a tempering valve or hot water mixing valve. There are many varieties.

I myself would use a

Prier C-108D08 faucet.

Check ebay for best price. This brand is the best made for quality.

Try this just make sure you disconnect the hoses between uses during winter.

The OP wants to only drill ONE hole through the wall.
There are many options if you bring both hot and cold out through the wall.

The first option from joed looks like it is exactly what I want. I just want a warm water all year. If I want cold I can just go to the spigot in the summer. Thanks

Hot water packs a powerful energetic punch when released into the cleaning equation. This energy also causes a reduction in the water’s surface tension allowing it to easily and more effectively penetrate the molecules of grease and grime.

Careful with hot water and your pressure washer. Most pressure washers are NOT rated for hot water.

I don't want hot water I want warm. Maybe 80 degrees. I fill buckets with it and dip my hand in it. I can not say for sure what temp I want it at with out playing with it but just warm . Also it is to use while cleaning vehicles in my garage during winter not pressure washing. Thank you for the info but those were never my intentions sorry if I was not clear.

I've always wanted warm water in my garage to wash my car during the winter!

What are you planning to do about the water runoff? Are you installing a drain?

 

[chadwilliam1]

I have no plans on installing a drain. I don't plan on giving my truck a full wash in the garage just using buckets to wipe it down. Even when it is 70 degrees outside and sunny warm water would be really nice for washing the truck using the regular spigot and using the warm water for my two bucket wash.

Put a vertical faucet in a place where an upper story wall is perpendicular to your garage, then drop the supplies down into the basement through the floor. You'll need an access panel or a drywall patch but that sounds easier than hammer drilling through 8" concrete. If you get freezing weather, use a frost free faucet. The shutoffs are always inside the warm space of your house. Even though your garage is heated, it's possible that someday the heat could go out or a cat might run across the laser and your garage gets left open overnight.
