Question about Pentair 011516 WhisperFlo FullRated Energy Efficient Pump 3Horsepower 230Volt
If pressure gauge on filter is low, then most likely problem is obstruction is suction side of plumbing, which includes a clogged impeller. double check impeller, this can be hard to get to without unbolting the two halves of pump, separating the two, and removing the diffuser so that you can fully inspect the impeller. You can try using a wire with a little barb on the end and trying to pick at the center of the impeller from within the pump pot (where the basket goes), but if this doesn't reveal anything, taking pump apart to reveal impeller is the best bet. Before you take the pump apart, (or after if you've already done so.) make sure pump basket, skimmer basket, and any leaf traps are cleaned out. Make sure any valves on the suction side are fully open to allow as much flow as possible. (you can open and close these later to single out the problem if it is a plugged vac line) Disconnect the cleaner from the wall or skimmer to eliminate a clogged cleaner from the possible causes. A bad o-ring, or air leak somewhere can also cause low, or bad suction. so make sure the pump lid o-ring is sealing properly. Also check the pipe that goes into the pump (suction side) If this is loose, or letting air into system, that will also affect suction. You should be able to find your problem if you check all the above. If not let me know by posting a comment, and I'll help you further. Every pool, and equipment are different, and there are endless possibilities to where your problem can be, but eventually you can narrow it down to the problem. Good luck and let me know how it turns out.
