I am dealing with the fixture in the photo. There are 2 water inlets, one for the washing machine, and one for a dish washer. The bottom valve opens and closes the water flow to to the bottom pipe. However, the top valve seems to have no effect whether open or closed and nothing but a drip comes out of this top pipe. Everything was working a few days ago until i shut off the top valve to fit a new dishwasher.
The turning mechanism of the top valve seems very light and I am thinking perhaps it could have broken loose from the valve so that the valve is shut regardless of the position of the handle. Is this feasible?
Would appreciate any pointers regarding the waterflow problem and how to resolve.
