This hot tub came with the house, always worked fine no problems at all. Yesterday I went out there and it had done a pretty good flood job in the room its in.
I opened the door to the electrical and notice the three tubes coming down from where the controls are on top. One of them (far one) is leaking, I feel inside it and it feels like some kind of rubber releaf valve with a nipple in the middle of it (see pictures).
What is this pipe for and can anyone help me out on how to fix it? Thanks in advance its greatly appriciated!
