Hi, I have a 1992 hunter 33.5. Underneath the head sink, the fresh water plumbing system has T-joint connectors (one for cold and one for hot) which are leaking. The T-joints connect the grey plumbing pipe at 2 ends, to the flexible hose from the tank and is connected to the T via a barb. The T-joint is also grey plastic. Does anyone know where I could purhace replacement T-Joints, either original manufacturer or something that will work? I spent a couple of hours at RV shops and Home Depot with no success. Thanks!!
