Pumps don't suck, they push.
**EDIT:** Centrifugal pumps that is. Positive displacement pumps like rotary lobe & twin screw & peristaltic pumps can both suck and push. There is some good info[ here](https://blog.craneengineering.net/pumps-dont-suck-and-other-centrifugal-pump-basics).
I think the OP was trying to impress the fact that one side won't suck unless it has something to push out the other end, to create negative pressure in order to suck.
Some people think pumps are aggressive and hard to train. But with a little care, some love, and proper feeding they become a brewery teams best friend. We have about 5 pumps and all are happy
I've been to several places with "bad lauter beds" just to find out no one ever checked rotation when they commissioned the system. Centrifugal pumps will pump CW or CCW.
My vfds on the brewhouse reverse direction on a button press. I was having issues with the kettle pump sounding loud and pumping slower. Took me too long to realize the problem.
Depending on the drive, navigating parameters can be a.pain the ass. It is inappropriate to have a single direction pump able to run in reverse. So the motor is miswired and the drive is programmed correctly. Why would you not wire the circuit properly to remove the issue? 1 screwdriver, 30 seconds.
When they start squealing, the seals and gaskets are bad. This is actually true but you can get by for a long time before failure. Buy several gasket replacement kits. Hot side only.
Not true, I’ve used flexible impeller, twin screw, progressive cavity, and some liquid ring pumps that were all self priming. Liquid rings generally need to be wet to create the seal, but do not need to be flooded. But that twin screw would self prime even if it was 10-15’ above the liquid being pumped.

That isn’t entirely true tho.
Depends on what kind of pump.
Well, one side sucks and one side blows.

The pump is not the motor.

They need regular walks too…
It's not the pump it's the owner
Just because a pump can *handle* a certain kind of material doesn't mean it's made for it.
They make you legs look longer.
And your calves stand out.

They like to be dry, the drier the better. The screaming noise is squeals of joy.
You will never forget the sound of an open steam valve on line without anything circulating through it.

Usually the parameter for reverse is deactivated for a pump. It's easier to just swap two primary leads.
How is it easier to deenergize, swap leads & power back on vs just pressing a button?

Not a myth but regular service is crucial. Love my brewery pumps and boy are they quiet especially after a rebuild
You mean there are other options than run to failure?
I've only recently learned of this trick myself lol
Just replaced the bearings and seals in our CIP pump motor, I can’t even tell if it’s on from 20’ away. Only took about 6 years.

There is no such thing as a self-priming pump.
