Checking the Impeller for Debris
To open the pump shut off power at the breaker and remove the six bolts and pull back the power end.[1]
Don't remove the back cover like he does in the video at https: //youtu .be/Hy1meV5Y4iQ.
Remove the diffuser and check the wear ring and impeller.
Drain Plug
It's 1/4" npt. Most drain plugs are 1/4" npt.[2]
The newer drain plugs are designed with an O-ring.
The O-ring plug is preferable if the pump hole has a flat spot for the O-ring to mate with.
A 1/4" npt plug will work in any case.
1991 and earlier, it's the regular plug (SPX1600V). 1992 and later, it's the O-ring plug (SPX1700FG).
The OD of the plug is about 7/16. That's the name, not really the size. It's like a 2 x 4 is not really 2x4.
