how to backwash intex pool filter

Author: Poolking - Swimming Pool Equipment Manufacturer

Intex pools are the go-to choice for many homeowners, offering a convenient and cost-effective way to cool off on a hot day. However, keeping a pool clean and healthy requires more than just filling it with water. Regular maintenance tasks, such as backwashing your filter, are essential to keep your pool in good condition.

In this article, we’ll go over everything you need to know about how to backwash an Intex pool filter. From what backwashing is to step-by-step instructions on how to do it, we’ve got you covered.

What is Backwashing?

Backwashing is a process where you reverse the flow of water in your pool filter, flushing out any debris and dirt that has built up inside. Periodic backwashing ensures that your filter remains in good condition by keeping it free of accumulated debris, which can clog up the filter and reduce its efficiency.

Why is Backwashing Important?

As we mentioned earlier, backwashing is essential to maintain the health and cleanliness of your pool. But what happens if you don’t backwash regularly? When debris accumulates in your filter, it restricts the flow of water, which can cause your pump to work harder to push water through the filter. This added strain on your pump can lead to decreased efficiency, increased power consumption, and even damage to your pump.

Now that we know why backwashing is important let’s get into the steps you need to follow to do it properly.

How to Backwash an Intex Pool Filter

Step 1. Turn off the pump.

Before you start backwashing, you need to turn off the pump that circulates the water in your pool. This will prevent any water from flowing into the filter while you’re backwashing, which could damage the filter or cause it to overflow.

Step 2. Turn the valve to the “backwash” position.

Next, locate the multiport valve on your filter. This is usually located near the pump and has several positions, including “filter,” “backwash,” “rinse,” and “waste.” Turn the valve to the “backwash” position.

Step 3. Turn on the pump.

Now it’s time to turn on the pump. This will create a reverse flow of water through the filter, flushing out any debris that has accumulated inside. Keep an eye on the water flowing out of the waste line, as this will indicate when the backwashing process is complete.

Step 4. Watch the water flow.

As the water flows out of the waste line, it will start out cloudy or dirty. Keep an eye on it until it becomes clear, indicating that the backwashing process is complete. Depending on the level of dirt buildup, this process can take anywhere from 2-5 minutes.

Step 5. Turn off the pump.

Once the water flowing out of the waste line is clear, it’s time to turn off the pump. This will stop the backwashing process.

Step 6. Turn the valve to the “rinse” position.

Now that you’ve backwashed your filter, it’s important to rinse it to ensure that any remaining debris is flushed out of the system. Turn the valve to the “rinse” position, and turn on the pump again for 1-2 minutes. This will flush out any debris that may have been left in the filter after backwashing.

Step 7. Turn off the pump and reset the valve.

Next, turn off the pump and reset the multiport valve to the “filter” position. This will allow water to flow through the filter, starting the filtering process once again.

Conclusion

Regular backwashing is a crucial part of maintaining a clean, healthy pool. By following the steps outlined in this article, you’ll be able to backwash your Intex pool filter with confidence, ensuring that your pool stays sparkling and clean all season long. Remember, a little maintenance can go a long way in keeping your pool in excellent condition. Happy swimming!

----Yes, they can. Silica sand is mainly used for filtration, while activated carbon is mainly used for adsorption. Silica sand is effective for higher water quality requirements. When use them together, silica sand should be placed on the bottom layer, and then activated carbon should be filled on the sand, but the cost of using two media is much higher.
