Hay guys I have a problem. My rt pro valve is leaking out of the on/off assembly. I'm pretty sure it's one of the orings and replaced the top oring but have replaced the bottom one. Now here's the problem I took off the bottom o-ring but now I can't get it back on. I'm hopeing you guys have and easier way to do this I was trying to take the on/off apart but I don't want to scar it to much. any suggestions.
