I have a Rheem RMHP-115 pool heat pump that is leaking water out of the bottom of the unit. The HP is not currently being used, but water circulates through the unit anyway and leaks 1/4“-1/2” of water daily. I have identified the leak to a T-shaped hose that is connected to the water manifold in two places and drains water to the outside of the unit (see photo). I am guessing that this is some type of pressure-release mechanism and perhaps a valve is stuck open. I just can’t imagine that Rheem designed this to leak on purpose. Any thoughts?
