Sounds like a problem I had with my spray port. Here is what I did:
- first make sure the exterior valve can depress - take a small screwdriver and move the brass valve. It took some effort on my end! If its stuck or does not move freely then take some silicone and lube it up! If it moves but no water there may be a pressure release (I'm not sure what it really is) on the inside of the quick release valve that is stuck. Depress this (again with some pressure) and the spray port will most likely work. Just make sure to drain your water before you take the spray port off! Attached is a link of the spray port part you need to depress after you have removed it from the TT. Take a plastic putty knife to remove the port from the back of
the TT and when complete. Don't forget to waterproof the thing once its back together! (
