3. Check Trailer Relief Valve. Remove and pressure test. Causes relief valve to pop on blower, burns heat plug out of blower, burns up and cracks tanks.
4. Inspect Check Valves, remove to inspect. Be sure flapper is sealing. Sometimes flapper comes loose and wedges in hot air line causing blower to melt heat plug, blower to burn up, relief valve to pop, and trailer to pressure up and unload slowly.
5. Inspect Pads. If trailer has pads, check for being plugged up. If trailer has flo cones, check them for wear or or holes and splits. Usually slow building pressure in tank. Sometimes the relief valve pops when trying to build pressure in the tank, heat plug may melt, or blower could burn up. If trailer has flo cones, while unloading check the small hoses around each hopper to see if they are hot. If they are cold, they are plugged up. If it has pads, check each hose to each hopper to see if it is hot. If cold, they are plugged up.
6. Check Butterfly Valves. The disc in the butterfly valve will wear off causing it to not shut off. The seat will crack or tear, causing it to not shut off. This sometimes causes you to lose tank pressure, or can cause plugged up product line.
