its when u starve the pump by having too little water to feed it and too much out. Basically the input cant keep up with the output. Throttle it back see if that helps.

i got 2inch pipe to feed it all the way to pump(reeflo 2"in 1.5"out),then 1,5inch ball valve as output to 1,5inch om 4-way and 4x1" returns as output.
anyone hear about om drum not indexing correctly?
thanks

Are you certain the intake strainer isn't clogged? The plumbing size looks good, but if the pump is being starved for water, it can and most likely will cavitate.

Problems prob with the 4way. Maybe see if its workin right or clean it? Maybe put a strap on the pipes to secure them better too, couldnt hurt
