This place was useless. The guy I spoke with was too cocky to listen to my question before answering me. I tried to ask again, and again was presented with a solution to a problem that didn't exist. I finally got him to shut up long enough to complete my question. Then he told me there was no solution or replacement part available. He said the valve unit needed to be replaced at a cost of $95.00.I found a solution elsewhere for $7.
