Does the problem decrease/go away if you slow the velocity of the water by putting a restriction on the outlet (pinch the hose with your fingers quick)?

link is down but i'll keep at it, thanks. ill try the velocity restriction when I get home. assuming it is that, what are my options to try to stop it?
