How many gallons is amtrol ST 12?
4.4 Gallons
Amtrol THERM-X-TROL® Water Heater Expansion Tank ST-12, 4.4 Gallons.
Why is there water in my expansion tank?
Dripping water is one sign that a valve may be blocked. This can occur as a result of mineral deposits or other debris. Some older expansion tanks lack the internal bladders used in newer models. This component is what separates the water and air pressure.
How many gallons is a st5?
operating pressure: 150 psi. Expansion tank volume: 2.0 gallons.
What is amtrol Turbulator?
Fresh Water Turbulator™ • Patented diffuser agitates incoming water to keep it tasting fresh and clean. • Water-jet scrubbing action prevents sediment from collecting inside the tank.
What is hot water heater expansion tank?
A water heater expansion tank is another small tank that is attached to the water supply pipe of the water heater. The expansion tank is designed to handle the thermal expansion of water as it heats up in the water heater, preventing excessive water pressure.
How can you tell if expansion tank is bad?
If it makes a dull thud rather than a hollow sound, your tank is full of water and needs repair or replacement. You can also gauge this by feeling the tank, which will be cool where it’s holding air and warm where it’s holding water. If more than half the tank is warm, you have a problem.
Should the water in the expansion tank be hot?
Expansion Tank Maintenance The top portion of the tank should feel warm to the touch, and the bottom portion of the tank should be room temperature. If the entire tank is warm, it is likely that the tank has completely filled with hot water, which occurs only if the diaphragm fails.
What is a good expansion tank?
If you have the opportunity to upsize, a 4.4 Gallon Thermal Expansion Tank is a good choice for water heaters from 50 to 120 Gallons. A larger tank provides additional protection by further reducing the pressure increase during a heating cycle.
What size expansion tank do I need?
General Guidelines for Sizing an Expansion Tank
| Water Heater Capacity | Supply Pressure (psi) | Expansion Tank Size |
|---|---|---|
| 40 to 60-gallon | 40-50 psi | 2-gallon |
| 40 to 60-gallon | 60-80 psi | 3.2-gallon |
| 80-gallon | 40 psi | 2-gallon |
| 80-gallon | 50-60 psi | 3.2-gallon |
What does a Turbulator do on expansion tank?
Antimicrobial Liner and Turbulator work together to keep tank surfaces clean. Neutralizes 99.9% of bacteria on contact. Safe, Silver-Ion technology only targets active microorganisms. Long lasting compound protects water reservoir lining for the life of the tank.
What does a Turbulator do?
A turbulator is a device that turns a laminar boundary layer into a turbulent boundary layer. Turbulent flow can be desired on parts of the surface of an aircraft wing (airfoil) or in industrial applications such as heat exchangers and the mixing of fluids.
What is an Amtrol ST-12 tank?
Description Amtrol ST-12 (Therm-X-Trol) is a water heater expansion tank, designed for use in domestic hot water heating systems to eliminate the potential hazards of water expansion. Water heater expansion tank is commonly installed in a domestic hot water system that contains a backflow preventer, a check valve or a pressure reducing valve.
What is a ST-12 expansion tank?
AMTROL ST-12 (Therm-X-Trol) is a water heater expansion tank, designed for use in domestic hot water heating systems to eliminate the potential hazards of water expansion.
What is the meaning of Amtrol?
Amtrol invented the thermal expansion tank to absorb expanded water in closed, hot water systems and protect the water heater.
What psi should the ST-12 tank be charged to?
The new ST-12 tank came pre-charged to 50 psi. It also came with a nice indicator cap on the bottom to show the condition of the tank and a plastic turbulator on the top. I had to remove the charge to insure the turbulator is installed correctly.
