Vacation Drain & Fill

Getting ready to head out of town for a couple of weeks and I implemented an auto drain and fill for my Grobo.
I purchased 3/8” OD 1/4” ID tubing from a hydroponics store along with the 1/4” barbed connectors.
See images.
With the door closed, the drain tube inserted into the drain pipe that my water softener drains into, and fill tube currently in a 3 gal bucket (7 gal bucket on order). Ran the drain and fill without any error or issue.
I have the Grobo plugged into a KASA smart WiFi plug to reset the machine if the drain/fill stalls.
