Steps to Drain Your Expansion Tank

Water Heater Expansion Tank

Water Heater Expansion Tank

Your expansion container has a single, yet remarkably crucial objective. It is made to be an over-flow remedy for a hot water heating device. It is a one-way device. As soon as the water gets involved in the expansion container, it does not recede into the primary hot water storage tank. If you have a closed-vent boiler based device, periodically the expansion tank will need to be drained of water to be charged for future effective over-flow use. You may need to call a plumber in Chicago to help with the following steps.

Action 1 – How to Determine if Development Container is Full

While the central heating boiler is running you could place your hand at the bottom of the storage tank. If you can detect warmth on the bottom of the storage tank, move your hand toward the top of the expansion tank. If it feels warm, then run your hand down the sides of the container and really feel where the temperature level of the container feels warm. The warm area of the tank is the region in which the water is sitting. If the container is mostly loaded with water it is time to remove it. This is important since water does not allow the correct pressure for the central heating boiler to function properly.

Action 2 – Prepare Central Heating Boiler to Drain Development Storage tank

At a minimum of annually, and sometimes two times a year, the expansion container must be drained. This will certainly aid to keep the air pressure that is essential for the boiler device to keep a healthy and balanced level, keeping your warm water system functioning correctly. It is advised to do the draining just before the winter time, typically early autumn and late spring. Turn off the switch for your boiler and shut down all the supply of water valves. If the central heating boiler system is warm allow it to cool off before dealing with it.

Step 3 – Draining the Storage Tank

Find the cleanup valve that is on the development storage tank. You could additionally place a five gallon bucket under the shutoff if you do not have a tube. The storage tank must drain totally. If it does not get rid of all the water then the tank will certainly not recharge atmospheric pressure properly. If the water stops being eliminated from the tank there can be an air pocket keeping the water from being released. Many times blowing air back into the expansion container will certainly pop this air pocket and enable the water to continue streaming. Know that once you stop blowing into the hose the water could come out rapidly. Once you feel the air pocket is released be ready to relocate the tube quickly from your mouth.

Action 4 – When Container is Empty

When the central heating boiler development tank is entirely clean, the cleanup valve needs to be closed, and the supply valve for the water has to be open. Inspect all pipelines and valves to ensure that they are not dripping from the extra water stress resulting from the draining procedure. Central heating boiler upkeep involves more than a periodic tank cleanup. If your boiler is 10 years or older then conscious maintenance is essential.
