Step 2: Turn Off Water
Turn off the water supply to your water tank before cleaning it. This step is crucial because you don’t want new water in the tank while cleaning. Fresh water can disturb cleaning and dilute cleaning chemicals.
Find and cut off your tank’s water valve or switch. This simple gesture keeps the tank water steady, letting you focus on cleaning.
Step 3: Drain Some Water
Step 3 makes cleaning a water tank without removing its precious contents manageable and practical. Draining some of the water may seem simple, but it requires a precise balance to maintain enough water for continuous use while allowing you to view the tank’s inside.
Start with a line long enough to reach the tank’s drain valve and a drainage area. The tank’s drain valve is usually at the base. This valve is usually a spigot-like fixture that may be opened and closed.
Prepare your drainage plan before opening the valve. Discharged water may contain sediments or toxins, therefore avoid regions where it could create difficulties. Safety and environmental responsibility should guide drainage.
Open the drain valve carefully with your hose attached. Water should flow slowly and steadily. The goal is to lower the tank’s water level, not empty it. By doing so, you generate an adequate tank area for cleaning.
Watch out for the water as it comes out. The outgoing water may initially carry loose debris and silt. This natural flushing effect removes impurities to start cleaning.
Carefully close the drain valve when the water level is right. Seal it completely to avoid water loss. Keep in mind that the tank has a partial water reserve for continuing use and cleaning.
Step 4: Tank Interior Inspection
After lowering the tank’s water level, inspect the interior visually. Use a bright flashlight to inspect the tank’s walls, floor, and corners for debris, silt, and algae. Pay special attention to edges, seams, and contaminant-prone areas.
The presence of silt or debris during this check indicates that your water tank needs a thorough cleaning. Algae or discoloration can also raise concerns about water quality. First, perform visual inspections to determine how much tank cleaning is needed.
Step 5: Interior Scrub
After identifying the portions of your water tank that need cleaning, start to work. Use your beloved clean water tank brush to meticulously scrub the tank’s interior.
Start cleaning from the top and proceed down. Covering every inch of the tank’s interior dislodges impurities and makes removal easier.
If stubborn stains or deposits resist your brush, use baking soda and water as a gentle yet efficient abrasive cleanser. Make a paste using these ingredients and apply it to the problem areas. Scrub gently with your brush. However, avoid using harsh chemicals or abrasives that could damage the tank’s interior or leave dangerous residues.
Step 6: Debris Removal
When you scrub hard, particles and sediment collect at the tank’s bottom. Scoop these particles out with a clean pail or container to avoid muddying the waterways. Keep doing this until all loose debris is removed from the tank. The more thoroughly you clean your tank, the better the water will taste.
Step 7: Disinfect Tank
Next, disinfect the tank after removing loose debris and silt. This is to kill any hazardous bacteria or microbes in your tank. This requires food-grade hydrogen peroxide or chlorine, both of which are safe for potable water.
Follow the manufacturer’s instructions to dilute your disinfectant. Typically, 1-2 tablespoons of disinfection are used every 100 gallons of tank water. Carefully pour the diluted disinfectant into the tank’s opening, distributing it evenly.
Step 8: Agitate and Sit
After adding disinfectant to your tank, carefully stir the water. This easy operation distributes the disinfectant evenly throughout the tank, touching all inside surfaces. Depending on the manufacturer, let the disinfectant sit for 30–60 minutes.
While waiting, the disinfectant targets and neutralizes any remaining bacteria or pollutants in the tank.
Step 9: Rinse Tank
After disinfection, the tank must be thoroughly rinsed. This rinse removes residual disinfectant, making water safe to drink.
Carefully direct a hose into the tank from a water supply. Run the water until the tank’s water no longer smells like chlorine or hydrogen peroxide. Your tank should have clear, unscented water, suggesting no disinfection.
Filling the tank completely is essential before continuing.
Step 10: Restart the Water Supply
After cleaning and disinfecting the tank and filling it with fresh water, reverse Step 2. It’s time to restart the water. Open the tank’s inlet valve or switch to let water in. This gradual replenishment restores your water tank’s capacity.
Step 11: Check Water Quality
The final level requires a long-term commitment. It’s important to monitor tank water quality after cleaning. Look for discoloration, odd smells, or bad tastes in the water. If you notice any abnormalities, the water quality may be degraded and require repeat cleaning and disinfection.
Cleaning a water tank without removing the water is difficult, but this tutorial gives you the knowledge and steps to do it. These rigorous processes ensure the quality of your stored water and save you the hard task of draining and refilling the tank.
