I have recently opened a cafe. Yesterday the soda fountain company installed a fountain. I discovered that the cold water line to the soda fountain had been turned off. When it is switched on, under the sinks, I can not get hot water in the sinks. So I need cold water to the fountain and hot water to the sinks and can not get both at the same time. What solutions can I use other than getting underneath the sink every time we wash dishes throughout the day.
