Do You Need a Pressure Reduction Tank for Your Water Heater? Here’s Why It’s Code in Anne Arundel County

If you’re a homeowner in Anne Arundel County, Maryland, and you’re on city water, there’s one crucial component your water heater must have: a pressure reduction tank. This isn’t just a best practice—it’s code. Neglecting this requirement can lead to serious plumbing issues, water damage, and failed inspections.
 
As your trusted local plumber, we’re breaking down why this small but mighty device is essential—and how Pasadena Plumbers can help you stay compliant and protect your home.
 
What Is a Pressure Reduction Tank?
 
Also known as a thermal expansion tank, this small tank is typically installed on your home’s water heater. When your water heater heats cold water, the water expands—creating pressure inside your plumbing system. Without a place for that excess pressure to go, it can cause:
            •           Stress on your pipes and fittings
            •           Leaky faucets or valves
            •           Premature water heater failure
            •           Even burst pipes in extreme cases
 
A pressure reduction tank gives that expanded water a safe place to go, keeping your plumbing system balanced and safe.
 
🏠 Why It’s Required in Anne Arundel County, Maryland
 
Anne Arundel County plumbing code mandates the installation of pressure reduction tanks on water heaters connected to city water. The reason? Backflow prevention valves, which are now standard on city water connections, keep water from flowing back into the main line—trapping pressure inside your home’s system.
 
That means the thermal expansion from your water heater has nowhere to go unless you have a properly installed expansion tank. Failing to install one can lead to code violations, failed home inspections, and major plumbing headaches down the road.
 
🔧 Signs You May Need a Pressure Tank (Or a Replacement)
 
If you’re not sure whether your system is protected, look out for these signs:
            •           Water dripping from the temperature and pressure relief valve (TPR valve)
            •           Banging pipes (known as “water hammer”)
            •           Fluctuating water pressure
            •           Short water heater lifespan
 
Our team at Pasadena Plumbers can inspect your setup and determine if your system is up to code.
