(See Fig. A, below, to find the wind zone you live in.) It won't cost a fortune, either. A little elbow grease and the building materials will all but guarantee your family's injury-free survival in any storm that comes down the pike. Keep in mind that a safe room can be more than just a storm shelter.
Expansion Tanks. The expansion tank is a vital part of your car's cooling system and acts as an overflow reservoir catching the water/coolant mix that is forced from your radiator as it heats and builds pressure in the system. cooling systems would explode under pressure or the coolant would be forced from the overflow tube on the radiator and leak onto the road. If your find yourself having to replace coolant too regularly then check your expansion tank and the rest of your system for leaks.
A properly sized American Expansion Tank eliminates these problems, by giving water a place to go when thermal expansion occurs.When a water heating cycle ends, or when any fixture is opened within the system, the impact of thermal expansion is reduced, and water drains out of the expansion tank back into the system. Expansion tanks are pre-charged with a 40 PSI air charge.If the inlet water pressure is higher than 40 PSI,the expansion tankâs air pressure must be adjusted to match that pressure but must not be higher than 80 PSI.
