So of course, the store I purchased this unit from no longer carries them... Typical Costco

I decided to take it apart and try to figure it out. To my surprise, it is incredibly well built for a product that was made in a country that isn't known for high quality things. Turns out the coupler that connects the main supply line to the internals of the shower head is just a nylon pipe nipple and it was cross threaded. Quick fix, I grabbed a brass nipple, now I'm in business
