Trying to figure out what is going on. When I first set up my Mag 9.5 return pump to my SCWD I had to back down the pump a little bit so the overflow could keep up. I noticed over the weekend that I can now run it wide open. Tonight I pulled the whole thing appart and cleaned everything. Nothing seemed very dirty and the pump showed no signs of wear. I tried running the pump without the SCWD directly back into the sump and wasn't impressed by the output power as I could cap off the pressure with my thumb without much effort. I put the whole thing back together and it seems no better. Now I'm wondering if I really tuned the overflow to keep up with the reurn or if the pump may be going.
Has anyone seen a Mag pump slowly die with no sign of wear?
