So, hoping someone can answer my question. Thanks in advance if you can.
I had a major leak on my Down East hottub. Tracked it down to, what I believe is called, the bleeder plug. The O-ring looks to be shot. The problem I am having is that I can't get it to screw back into the fluid end. I have not replaced the o-ring and don't know if I may have a bigger problem. It somewhat screws in when I take the o-ring completely off. I hope this makes sense and it's a common problem. I have pictures of what I am calling the bleeder plug.
