what is the solution for water pump knock in shower of 2021 Tab s

Tabnero

water pump on, tank full, turn on shower and cycle some water and the pump makes a significant knocking sound. I thought it was air trapped in the line so I changed the position of the sprayer nozzle but, no change. Ideas?

It depends on the source of the knock.  Only happening when the shower is on?  Then it might be the shower lines banging against the wall behind the shower.  Here is a thread.
