What Causes High Pressure in Pool Filter

Keeping our pool clean is important to maintain its health and extend its lifespan. A pool filter plays a crucial role in keeping the water clean, remove debris, and maintain proper chemical balance. However, sometimes filters can experience high pressure, which can be a sign of trouble. In this article, we will explore what causes high pressure in pool filter and discuss solutions to prevent it from occurring again.

1. Understanding Pool Filters

Before we dive deep into the causes of high pressure, let's first understand how a pool filter works. Basically, a pool filter is designed to trap, collect, and remove impurities and debris from the water in your pool. There are three types of pool filters: sand, cartridge, and DE (diatomaceous earth). Each type has its own advantages and disadvantages, but they all work in similar ways. Water flows through the filter, and any debris gets trapped in the filter element, which needs to be cleaned periodically.

2. Common Causes of High Pressure

High pressure can happen when the filter is clogged or dirty. A dirty filter can put a strain on the pool pump system and prevent water from flowing properly. Below are the most common reasons for high pressure in a pool filter:

- Dirty Filter: Dirty filters are the most common cause of high pressure in pool filters. When a filter becomes dirty or clogged, it restricts the flow of water, causing the pressure to increase.

- Under-Sized Filter: An undersized filter cannot handle the amount of water flowing through it. In this case, the filter will become overwhelmed, and its pressure will increase.

- Faulty Valve Position: A multiport valve is used to direct the water flow to the filter, backwash, rinse, or waste. If it is not in the correct position, it can cause high pressure in the filter.

- Clogged Skimmer or Pump Basket: If the skimmer or pump basket is clogged with debris, it can restrict the flow of water to the filter, causing the pressure to increase.

- Broken or Worn Pump: A damaged or malfunctioning pump can cause the filter pressure to increase. Pump problems can be caused by a clog or a faulty impeller.

3. How to Fix High Pressure in Pool Filter

Once you have identified the cause of high pressure, you can take steps to fix it. Below are some solutions to get your filter back to normal:

- Check and Clean the Filter: The first step is to check and clean the filter element. This will remove any built-up debris and gunk, allowing water to flow more freely.

- Check the Valve Position: Make sure that the valve is in the correct position. If it is not, adjust it accordingly.

- Check the Pump and Motor: Examine the pump and motor for damage or wear. This may require the help of a professional.

- Check the Skimmer and Pump Basket: Clear any debris from the skimmer and pump basket to ensure proper water flow.

- Add a Backwash or Rinse: A backwash or rinse can help clean the filter and reduce pressure. Follow the manufacturer's instructions to perform these tasks.

4. How to Prevent High Pressure in Pool Filter

Preventing high pressure in your pool filter is the key to keeping it in good condition. Below are some preventative measures you can take:

- Clean the Filter Regularly: A clean filter will prevent debris from building up and clogging it. Make sure to follow the manufacturer's instructions for cleaning the filter.

- Use the Right Filter Size: Make sure you have the right size filter for your pool. An undersized filter can cause high pressure and lead to wear and tear.

- Clean the Skimmer and Pump Basket: Regularly cleaning the skimmer and pump basket will prevent debris from accumulating and causing blockages.

- Conduct Regular Maintenance: Conduct regular maintenance on your pool system, including the pump, motor, and filter, to extend its lifespan and prevent problems from arising.

- Schedule Professional Services: Have a professional inspect your pool system regularly to catch potential problems before they become serious.

In conclusion, a high-pressure pool filter can indicate a problem with your pool system. By understanding the common causes of high pressure and taking appropriate action, you can prevent future problems and enjoy clear, clean water in your pool.
