Upon arrival, no one here was informed by the office, noticed water in in garage but water looked clean and unlike drain water so I tested the hot side hose and ran water for nearly 8 minutes no back up nor sound of back up, after further investigation noticed cold side plastic nipple in washer wash leaking thus leads me to the conclusion that a appliance repair man is needed in this situation. On my end I took supply lines off to inspect rubber seal and they appeared fine but were loose and dripping as well so I tightened them back and stopped leaking.
