Bad/Weak water pump?????

I like to use Tide HE detergent to flush with. It has helped me with doziers, tractors and cars and is cheap and easy. I have also had impellers slipping on shaft which has caused me lots of problems trying to find cause. I had installed a new water pump on an 8" water pump with a Chevy 292 cu in running on propane and it would ice up and die. I knew I had a new pump so I thought that part was eliminated. I lost lots of sleep and got up one morning at 5 am and took the new pump off and found impeller slipping. Parts house got their eyes burnt
