Hello, I have a 2010 Hot Spot RELAY spa. It is in good overall condition for its age and would like to keep it going as long as possible. I have found a small leak, but can not find the parts online. I am a plumber not a spa tech so I'm looking for some help with identifying and perhaps terminology. The fitting that is leaking is located inside of the filter basket area. It is a small fitting that goes through the tub with a barb on the other side, that has a small clear hose, maybe 5/16 dia, that runs to a barb on the elbow on the intake side of the pump. The slow leak turned into a larger leak as i snapped the barb off messing around with it. It looks like it may not be threaded, and there isn't a nut on the backside of the fitting. Perhaps it is epoxy or cemented in place as it is the suction side not the pressure side of the pump. I attached a photo. Any help is greatly appreciated.
