A water pressure gauge is crucial because it provides an accurate reading of your home's current water pressure. Without it, you cannot precisely determine if your pressure is too high or too low, making proper adjustment impossible. It ensures you meet the recommended 50-60 PSI range and helps prevent damage to your plumbing system.

Ignoring incorrect water pressure can lead to significant problems. High pressure can cause pipes to burst, damage expensive appliances like water heaters and dishwashers, and wear out faucets prematurely. Low pressure, conversely, can lead to frustratingly weak showers and slow filling times for fixtures, impacting daily comfort and efficiency.

Adjusting a PRV usually takes 15-30 minutes, especially if the valve is easily accessible. This project is considered beginner-friendly because it primarily involves locating the valve, using a simple pressure gauge, and making small, controlled adjustments with basic tools. Patience and incremental changes are key to success.

First, ensure the locknut on the PRV is fully loosened before attempting to turn the adjustment screw. If the pressure still doesn't change after several turns in either direction, the PRV itself might be faulty or stuck. In such cases, the valve may need to be repaired or replaced by a professional plumber.
