So as title says I drained my 5kish gallon spa because my system was running at 0 psi. Pump would start strong when I turn it on and run around 15 psi and within 5 seconds drop to 0 psi. I don’t think it was sucking in air....when I opened the pump lid it had a strong suction sound and feeling (100% assumption btw). I fee there is a clog in my suction line. I drained the pool so I could close off the main drains and it turns out they were 100% clogged from the previous owner. The main drains feed into the skimmer which I also learned.
Now that it’s empty I’m trying to blow air and suck air through both ends with a shop vac. Weird thing is I can blow air from my skimmer line and suck air from the pump but not vice versa. In my professional opinion (sarcasm) I’m thinking there is a clog that’s moving around and blocking the path which coincides with the pump working strong for a few moments then sucking at sucking. Or....is it just a bad pump which needs replacing? Already opened the pump and checked impeller etc. thanks!!!!!
