Main water entry Plumbing services in Phoenix Valley
Your home’s main water entry is where city water first enters your plumbing system, and it’s the best place to control pressure and protect your pipes. Proper water pressure keeps fixtures, appliances, and hose bibs from wearing out early, while a correctly installed pressure vacuum breaker (PVB) helps prevent contaminated water from flowing back into your drinking water. Together, these parts make sure your water is safe, reliable, and flowing at the right pressure throughout your home.

Main Water Entry Components
Main shut off valve
Your main shut off valve is the master control for all the water coming into your home. In an emergency—like a burst pipe, leak, or water heater failure—turning this valve off quickly can stop water damage and give you time to call a plumber. Knowing where it is and that it works properly is one of the simplest ways to protect your home and plumbing system.
Pressure Reducing Valve
A pressure reducing valve (PRV) lowers the high pressure coming from the city water line to a safe, steady level for your home. When pressure is too high, it can stress pipes, water heaters, and fixtures, causing leaks, noisy pipes, and early failure. A properly set PRV helps protect your plumbing, keeps water pressure comfortable at faucets and showers, and can extend the life of your plumbing system and appliances.
Pressure Vacuum Breaker
A pressure vacuum breaker (PVB) is a safety device that helps keep dirty water from flowing back into your clean drinking water. It’s usually installed on irrigation or outdoor water lines and opens to let air in if the pressure drops, breaking the vacuum that could pull contaminated water backward. A properly installed and tested PVB helps protect your family’s water from fertilizers, soil, and other outdoor contaminants.
Hose bib
A hose bib is the outdoor faucet where you connect a garden hose to get water outside your home. It’s used for watering plants, washing cars, cleaning patios, and other outdoor jobs, so it needs to be properly installed and sealed to prevent leaks and wall damage. Over time, worn hose bibs can drip, freeze, or break, wasting water and causing problems. Other common names: outdoor faucet, spigot, sillcock, garden tap.
