10 Easy Steps on How to Drain RO Tank

Step 1. Locating the Drain Valve

The first step in draining an RO tank is locating the drain valve. The drain valve should be located on the bottom of your unit and can be identified by a round knob or handle.

If you cannot find yours, consult your owner’s manual or contact the manufacturer for assistance.

Step 2. Preparing the Tank

Once you have located the drain valve, it’s time to prepare your tank for draining. Before you do this, make sure that you are wearing gloves and safety glasses (optional but recommended).

Now, use a flat-head screwdriver to remove the cap from the valve. You may also need to use a Phillips head screwdriver if there is a locking nut on the valve. Once removed, remove any other pieces blocking access to the tank and set them aside for now.

Step 3. Attaching a Hose

Once you have cleared away any blockage from around the drain port, attach one end of the garden hose to the port. Make sure it fits securely, and use a wrench if necessary to tighten it all the way. Don’t forget to put gloves on before touching the hose and port!

Step 4. Open Drain Valve

Now that your tank is ready and the hose is attached open the drain valve and allow water to start flowing into your bucket or container. Be careful not to splash any water on yourself during this process! Otherwise, you should be able to stand back and let the tank drain.

Step 5. Empty Tank

Allow the tank to empty completely until you can no longer see any water in it. When finished, close the drain valve and disconnect the hose from the port. If you were using a bucket to catch the water, properly dispose of it according to your local regulations.

Step 6. Cleaning & Reassembling

At this point, you may want to clean out your RO system and components before putting them back together. If so, follow the manufacturer’s instructions on properly doing this. Another good idea is to replace the gasket on the drain valve before reassembling it.

Step 7. Reattach Components

Once your tank is clean, reattach any components that you removed earlier (such as the valve cap). Use a wrench if necessary to make sure it is secured tightly. Another important step is to make sure that all of the tubing and connections are secured.

Step 8. Refill Tank

Now it’s time to refill your RO tank with fresh water! Follow the instructions in your owner’s manual for how to do this properly, as each system may vary slightly from one another. Once filled up, close the fill port and move on to the next step.

Step 9. Sanitizing & Testing

Before you reuse your RO system, sanitizing and testing the water for quality is important. Use a chlorine-based sanitizer and a TDS meter (Total Dissolved Solids) to ensure the water is in good condition before use. Remember, this step is essential for the health and safety of your drinking water!

Step 10. Enjoy!

Now you’re all set! As long as your tank has been properly drained and refilled, you should be able to enjoy clean, filtered water with your RO system once more. Just be sure to check and maintain your system for optimal performance routinely.

5 Additional Tips and Tricks

2. Make sure always to wear protective glasses when draining your tank and connecting/disconnecting hoses, as water can spray unexpectedly.

3. Sanitize the entire system at least once a month (unless otherwise stated in your user manual).

4. Regularly check for any leaks at all of the fittings and connections on your RO system.

5. If you don’t have one already, consider investing in a TDS meter so that you can keep track of how clean your water is over time! This will help ensure that your drinking water remains safe and healthy.

With these tips in mind, you should now have the knowledge and confidence to drain your RO tank properly.

5 Things You Should Avoid

1. Don’t leave the drain valve open for too long, as this can cause damage to your system.

2. Avoid using any harsh chemicals when cleaning your system, as this can affect the taste and quality of your water.

3. Don’t forget to reattach the valve cap after draining your tank – this will help to prevent any potential leaks or contamination.

4. Never mix different forms of chlorine together when sanitizing, as this could create harmful by-products.

5. Avoid using hot water or high pressure washers inside the tank, as this can damage components or cause corrosion.

By keeping these things in mind, you should be able to safely and effectively drain your RO tank with minimal problems!

How Do You Flush a RO Tank?

Flushing your RO tank is essential for keeping it in good working order and preventing any potential contamination of your drinking water. This can be done by simply draining the water out of the tank, then refilling it with fresh, clean water. You should also make sure to sanitize the entire system at least once a month.

Finally, use a TDS meter to check the quality of the water after flushing to ensure that it is safe for consumption. Following these steps will help keep your RO system running smoothly for many years to come!

By following this guide on how to drain an RO tank, you now have the knowledge and confidence to properly maintain and flush your own system! Proper care and maintenance are essential for always having clean, safe drinking water. 

So make sure to check and sanitize your RO tank regularly, and always use a TDS meter to test the water for quality. Now you can enjoy clean, filtered water with your RO system once more!

Sanitize Your Ro Tank Regularly

Why is Your RO Tank Not Emptying?

If your RO tank is not completely emptying during the flush process, there could be a few reasons why.

Firstly, check that all of your hoses and fittings are properly connected and free from any obstructions. Then make sure that the drain valve is open all the way so that water can flow freely out of the tank. You should also inspect for any leaks within the system, as this could cause water to back up instead of draining properly.

Finally, you may need to replace the pressure switch in order to restore proper functioning. If none of these solutions seem to work, it’s best to consult an experienced technician for further assistance.

Conclusion

For any homeowners out there facing the task of draining a RO tank, it doesn’t have to be an intimidating venture. With the right tools and preparations, you can make sure that the job gets done correctly and with little hassle. If you don’t have any experience in this matter, it’s always worth getting some assistance from a professional to ensure you’ve got all the steps spot-on.

That being said, if you want to know how to drain RO tank, make sure to follow our instructions carefully—and wear gloves! After all, the last thing you want is for your hands to become slimy or sticky before your tank is back up and running.
