I think I can elaborate on this.
Number one is pressure, much higher pressure when using hot. Adjust it down. Pump should only be running for about 10 seconds or less till shut off. Make sure you set the pressure in your controller up with all the hose out, because hose pressure reacts differently when coiled up on the hose reel.
The second problem that occurs is that the hose pulls and twists off when you have you reel off the whole length of hose. I've used a cabletie to tie the hose down.
