What does a water regulator look like and how does it function in a plumbing system?

A water regulator is a small, cylindrical device typically made of metal or plastic. It is usually installed near the main water supply line in a Plumbing system. The regulator works by controlling the pressure of the water flowing through the pipes. It has an adjustable valve that restricts the flow of water to maintain a consistent pressure level, preventing damage to pipes and appliances.
