Hi everyone, I am fixing some odds and ends on my pop up to prepare for our first voyage. My popup comes equipped with a shower. When I hooked up my city water and tested the sink facets. All was good. Then tested the shower hot and cold. All good. Then, while outside I noticed a water leak. Notice in the picture that these are my hot and cold lines going to the valve inside trailer. But in my case, i see that they have a T installed. So water can go to valve and something else. Is this standard feature on this popup? Seems this is a modification of some sort, but why? Why would someone want to attach these T's. Is it to hook up some other water source? I need to repair it and thinking of just removing the T and installing an elbow to allow normal water flow. Anyone out there see this type of configuration?
