Hello all, this is my first post and I hope someone can help.
The faucet in my galley seems to be stuck in the open position. When I turn on the pump the water just starts to flow into the sink ignoring the fact I have both valves turned off. Is there a way to fix this or do I just have to replace the entire faucet?

Thanks in advance for the feedback!!
