Is there a connector for a washing machine water outlet, that has two
separate water outlets?

One would supply water to the W/M, and the other could be used for an
external water hose like to water down an outside patio on the 2nd
floor of my condo.

A splitter, I guess you might call it.

How does it work?
How do you switch it back and forth?
Is this worth my trouble?
Any leaking to speak of?

I have very little experience with plumbing.

I also am 71yrs. old with bad pain in my hands did you need to know
that? :-)

Thanks for any help. I read this ng all the time...very good advice
given... :-)
