In case you need to refresh : pump-will-not-prime-i-ve-tried-the-basics-t12473.html
Current status: pump is sucking some water but not enough to get a full prime or register any pressure on my gauge. I can see a few bubbles comng out of the returns.
I hired a "Pro" to come look at it. He took the pump apart and checked the impeller, lubed all of the O-rings, checked for any leaks around the plumbing. Bottom line: he's not sure why there is low pressure. He thinks that the suction line is either blocked by something or it is leaking. He offered to blow it out but he doesn't do leak detection. I have tried the "drain king" on both ends of the suction line to no avail.
Anyone have anymore DIY advice?
