Check Valve

A check valve (one-way valve) is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.


Fuses vs Circuit Breakers

Fuses must be thrown out and replaced completely when blown.

Circuit Breakers are easily reset if tripped, are the most common form of overload protection found in homes.

Circuit Breakers trip. Fuses blow.
