The better way is to get a sack of clean sand (might need more depending on hopper design) dump it in the bottom of the hopper stroke the s tube a few times to push it into all the places that you usually have to chip out after a long pour. Not worth the hassle in my opinion unless pumping longer then 3hours. I was told is called "sand packing the hopper"

we did this years ago on the whiteman pumps these things were nightmares to washout , but I found it was easier to washout without the sand in the in the newer pumps unless its just a very long day , the sand tends to cause build up is what I have seen , if you have a hopper with large dead spots no doubt the sand or dirt will help.
