Jop, I kind of think that you could have sued Vendor-X.
Now regarding the reduction thread, some vendors are now saying that you should consider having a pup of at least 5 to 10 times the diameter of the line between the nozzle and the elbow or first obstruction in the suction line. Has anybody had to deal with the same issue? I think that it is related to what type of pump you are dealing with, but some companies are developing a “trend” to establish that criteria for all pump suctions. Which is wrong because:
“In piping there is a reason for everything”

I’m not mocking your friend, he was right, but not just for piping, that applies to life in general, he must have been a cool guy.

Cheers!
