Trust Las Vegas's Specialists for Your Expansion Tank Needs
At Water Heaters Today LLC, we specialize in the technical components that keep your water heater running safely and efficiently. A hot expansion tank is an important part of modern plumbing system’s in Las Vegas and is not just a basic water heater “add-on”.

Water Heaters Today LLC technicians makes sure your water heater system is fully protected. Our service includes:
System Assessment: We verify if your home has a closed-loop system and requires an expansion tank, as well as check your drain pan.
Correct Sizing & Pressurization: We install the right size tank and, most importantly, pre-charge it to match your home’s specific water pressure for it to work correctly.
Failed Tank Replacement: If your existing thermal expansion tank is old, waterlogged, or has failed, we can quickly replace it to restore your hot water unit back to its proper functional state.
The Benefits of Having a Thermal Expansion Tank
Installing a thermal expansion tank is one of the smartest and most affordable ways to protect your plumbing and extend the life of your water heater.
Prevents Tank Failure: It absorbs the constant pressure spikes that flex and weaken the inner lining of your water heater tank over time.
Required By Local Las Vegas Plumbing Codes: If your home has a check valve or a backflow preventor installed on your water supply line, an expansion tank is mandatory to comply with local codes. A new water heater will not pass inspection without one.
Will Stop Annoying Leaks: An expansion tank reduces the strain on your T&P valve, faucets, and other fixtures, by reducing pressure. It will also heavily prevent chronic drips and leaks.
Protects Your Water Heater From Damages: A professionally installed expansion tank is a small investment that will have you avoid a premature, multi-thousand-dollar water heater replacement in the future.
