The plumbing for the garage sink originally went through the garage wall and ran to the sink on the garage side. I was advised to bring that plumbing into the house to protect it from freezing and to install freeze proof spigots for the supply on the garage side.
I worked with what I had at first. Took a full afternoon to drill holes in the drywall and install the outdoor spigots and connect to the existing drain pipe. I had used the back plates that came with the spigots and just bolted them to the drywall.
They seemed firm enough but upon reflextion there was nothing I could do to stabilize them if the drywall cracked from the pressure of turning them on and off. I had also created a huge turn around to the existing drain that just looked weird.
So I decided to take apart what I did one day and do it again the next. I installed a board to back up the faucets and support the drain pipe too.
I drilled holes through this board for the faucets and the drain rests on top of the board.
Then I cut out all of the drain I had assembled and realigned the drain pipe with a new cleanout and a new tee fitting that faced the right direction.
The new drain looks more normal and should function better too.
The faucets are now screwed through the drywall into the board making them much more sturdy.
Finally I completed the supply connections and the rough in was done.
I guess I’m glad I did think twice about this install.
