Upstairs Laudry supply

[ll1542]

I am moving our laundry room upstairs and I have a vertical sanatee to tie into for the drain which is also vented from an adjacent bathroom. However, all the water lines to that bathroom are 1/2 pex lines run from the basement trunk line to each fixture. There are three cold (two sinks, and toilet) and two hots (sinks) running from the basement to that bath. My question is can I tee off those sink lines for water supply to the washer? Or can I dedicate two for the washer and then use the other one for supply to the two sinks? Just a thought so I do not have to run another line from the basement all the way upstairs. I did pull permits so I am hoping one of these two scenerios will be leagal. Thanks for the help.

Good idea use hot and cold from one sink then tee off the other sink to provide hot and cold to the sink you stole water lines from . 2 lavs on a 1/2 inch are fine

Laundry is a start-stop water flow. I would avoid sharing 1/2 inch pipes carrying laundry load with bathroom shower.

I think there should separate set of pipes for the washing machine if practical.

A bathroom with a shower should have 3/4 for the cold.
