It is not that hard to clean and maintain a plastic water storage tank. In fact, you probably don’t need to hire an expert to perform regular inspection or basic cleaning. With a complete set of tools and an easy access to the unit, you just need to reach every part of the interior for scrubbing and rinsing.
Here’s a step by step guide on how to do maintenance on a plastic water tank:
Fully drain your unit.
This is very easy to do when you’re cleaning a small tank. But if you’re working with a large unit, make sure that you’re draining into a location that can handle a large volume of water. To get rid of excess liquid that won’t fully drain, you may use a pump. For leftover moisture, a towel must do the trick.
Scrub the interior walls.
You have to remove all the built-up grime and algae inside the tank. Diligence is the key. Power washers are a great tool for this process, as some units don’t allow enough room for you to easily reach in and scrub the interior yourself. If the dirt is too much to handle, you may use a mild abrasive, such as baking soda, that can help break down the debris. Then, rinse out the dirty water that has accumulated throughout the scrubbing process.
Disinfect with bleach solution.
Wear disposable gloves and eye protection for this step. Prepare a tablespoon of bleach per gallon of water and scrub the solution on the interior walls. Make sure you can reach every surface of the tank. If it’s not possible, use a floor mop with an adjustable handle.
Let the solution sit.
Stretch your back and wait for at least two hours. This is just enough time to kill off any stubborn bacteria or microbial contaminants inside the tank.
Rinse the tank out again.
This time, you have to be as thorough as possible. It is a crucial step especially if you’re using your plastic tank as a drinking water container. If you see any soapy quality or bubbles, that means you’ve insufficiently rinsed out all of the bleach. It should be enough once the water runs clear. For your safety, avoid doing this step in any spot near to where your septic system may be buried.
Test the water and measure chlorine levels.
This is something you’ll want to do even if you’re sure that you’ve rinsed all of the bleach from the tank. You’ll need to do this before fully refilling your tank and using your system again. Rinse again if necessary.
