If you want to see something really neat; let a pumper sit in the cold w/ out draining the tank or the pump and allow it to freeze! Easy to replace an engine, try to replace a 2,551gpm Hale pump and 2500gal Poly Tank. Nearly the whole truck has to come apart. That happened to us; the tank froze at the scene of a fire and snapped the hose bed in half; buckled the side of truck. We heard a snap as the overflow valve blew off and landed 80+/- feet away. The ladders flew off, the compartments popped open at the same time the air packs fell out, flashlights fell out, and finally a Storz relief valve blew off the truck... water was running out all of the compartments. The pump chamber was cracked, all of the pipes were cracked, the butterflyvalve was bent and the electrical system was destoryed. When the pump blew up, it was in active pump gear and still set on auto throttle of 150lbs. Problem was the pump was full, tank was full, and nobody was using the hoses that were pulled off. Classic pump operators error. When the hoses were shut down, the pump gear should have been deactivated and master drains opened. The result of the explosion ruined the entire truck. It would have cost more to rebuild it than to buy a new one. It was totaled "due to forces caused by nature".
It was a spectacular site, I'm glad the pump operator wasn't anywhere near the truck; he probably would have been killed when the storz valve blew off.
