how to tell if your pool filter is bad

Author: PoolKing - Pool Sand Filter Manufacturers

Introduction:

Having a swimming pool is a luxury that anyone would love to have. However, maintaining it can be a daunting task. The swimming pool is like a body of water that requires maintenance to keep it clean and healthy for swimming. One of the essential parts of the swimming pool is the filter, which plays a significant role in cleaning debris and keeping the water clean. Therefore, it is crucial to pay attention to the pool filter's condition to ensure your pool remains clean and healthy. In this article, we'll discuss how to tell if your pool filter is bad and what to do about it.

Understanding the pool filter:

Before we dive into determining if your pool filter is bad, understanding how the pool filter works is vital. The pool filter is responsible for filtering out contaminants such as dirt, debris, and other materials from the pool water. There are three main types of pool filters: sand filters, cartridge filters, and diatomaceous earth filters. The three types have their advantages and disadvantages, but regardless of the type of filter you have, it is essential to maintain it properly to avoid problems.

Signs that your pool filter is bad:

1. Dirty pool water:

The primary function of the pool filter is to clean the pool water, and if your pool water is dirty, it could be a sign that your pool filter is bad. A dirty pool can also cause skin and eye irritations, so it is essential to keep the water clean.

2. High-pressure gauge reading:

Your pool filter has a pressure gauge that measures the pressure inside the tank. If the gauge reading is consistently high, it could be a sign that your pool filter needs cleaning or replacing. A high-pressure gauge reading is an indication that the pool filter is clogged, and water cannot pass through it freely.

3. Low flow rate:

If the pool filter is not working correctly, it can affect the flow rate of water. You may notice that the water seems to be flowing slower than usual, indicating that the pool filter is not working correctly.

4. Pool filter is making strange noises:

If your pool filter is making strange noises, it could be a sign that it is not working correctly. You may notice strange noises such as gurgling, whistling, or grinding sounds, indicating that there is a problem with the pool filter.

5. Short filter cycles:

If your pool filter is not working correctly, you may notice that the filter cycles are shorter than usual. This means that the pool water is not getting filtered for the required amount of time, leading to dirty water.

What to do when your pool filter is bad:

If you have noticed any of the above signs, it is essential to take action immediately to avoid further damage to your pool. Here are some steps to take:

1. Clean the filter:

Before replacing the pool filter, try cleaning it first to see if it improves its performance. Cleaning the filter involves backwashing, which is the process of reversing the water flow to flush out the debris from the filter's media. You can also try soaking the filter in a cleaning solution to remove any mineral buildup.

2. Replace the filter cartridge:

If cleaning the filter does not improve its performance, it's time to replace the filter cartridge. The filter cartridge is a replaceable part of the pool filter, and it should be replaced every six to twelve months, depending on use.

3. Replace the sand:

If you have a sand filter, you will need to replace the sand every three to five years, depending on use. The sand grains can become worn or clogged, reducing the effectiveness of the filter.

Conclusion:

Maintaining your pool filter is crucial for keeping your pool clean and healthy. Signs that your pool filter is bad include dirty pool water, high-pressure gauge reading, low flow rate, strange noises from the filter, and short filter cycles. If you notice any of these signs, take action immediately, clean the filter, replace the filter cartridge or sand, and seek professional help if needed. By maintaining your pool filter, you can enjoy clean and healthy pool water all summer long.

----It is best to replace the silica sand of sand filters every 1-2 years for the following reasons:
a During backwashing, the filtration bed volume will expand upwards by 1.2 to 1.3 times. The water flow will drive the filtration layer to flow up and down, causing the filtration material particles to collide with each other. Backwash will let the small sand evacuate.
b.Some silica sands will be welded when the acid and alkali are changed due to insufficient purity;
Therefore, the longer the time, the worse the filtering effect of the sand tank. Since backwashing will consume and take away some sand, we need to replace the sand in the sand tank within the specified period.
After about 5~10days ,or when the reading of the pressure gauge on the pump side of the filter has increased by about 0.2bars since the last backwash , backwash the filter as follows:
1. Stop the pump
2.Close the valves on the suction and return lines.
3.Open the cover of the pump and empty the filter gasket .
4.Refit the cover
5.Open the valve to the drain outlet
6.Turn the lever to BACKWASH
7. Open the valves to the suction and return lines.
8.Start the pump .Rinse the filter for about 1 to 2 minutes until the water in the sight glass is clear .
NOTE : Any electric heater must be off .
9. Stop the pump
10. Turn the lever to RINSE , start the pump and rinse for about 15~30 seconds. Stop the pump and turn the lever to FILTER . This is the normal operating position .
11. Close the drain outlet valve and start the pump . Switch on the electric heater if any .
