I haven’t had an IP apart yet, I need to do that soon. But I was messaging with Justin and he explained to me how activating the cold advance opens the regulators check valve / drops all housing pressure. If the check valve gets stuck it won’t let housing volume out so it would affect the backside of the plungers. Aka like if you’re return is blocked. One of the troubleshooting steps I ran the ip return to a bucket and no difference so I figured wasn’t that and then when I jumped the cold advanced and things started to work I didn’t know what I didn’t know besides either coincidence or something unstuck.
@tbowker happy?
