Determine the area where you will be installing the galvanized water tank. Ensure the location as well as the size correspond with the city zoning laws, and have a city inspector work with you to ensure everything is done according to code. Use an excavator to dig the hole for the water tank, as well as any corresponding trenches to run pipes from the tank to the house, and from the tank to the well.
Complete any electrical wiring on the pump before lowering it into the well, and follow the manufacturer's instructions for proper installation procedures (which will vary by manufacturer). Lower it into the well and ensure that a bleeder valve and snifter valve are installed on the pump line, with the proper length in between (for example, a bleeder valve must be at least 5 feet below the snifter valve). Also ensure that a shut-off valve is installed somewhere where it is easily accessible in case of maintenance down the road.
Hook up all of the connecting pipes to the water pump for the well, in addition to the pipes running to the house. Test the pump from the well to ensure that the water is properly running through the pipes, and check for sand, mud or other debris in the water. Run the water from the pump into the tank until it comes out clean, and filter out the debris from the bottom.
Fill the tank after you have double-checked all of the connections to ensure that your pressure valves are working. Run the water to the house or building and check the taps in the sinks to ensure that you are getting pressure from the tank to the pipes. Cover the tank with the excess dirt from the hole you dug for it, and landscape as you see fit.
- Galvanized water tanks may also be installed above-ground and enclosed for ease-of-use in certain locations. Ask your city inspector for more detailed information.
