Author: Poolking - Swimming Pool Equipment Manufacturer

Swimming pools provide a great source of entertainment and relaxation for families and friends during hot summer months, but pool maintenance is crucial to ensure the pool remains in good condition for years to come. One of the essential parts of a swimming pool is the pool filter which keeps the water clean and free from debris. Hayward pool filters are an excellent choice for keeping your pool water clear and sparkling. Over time, a Hayward pool filter’s pressure gauge may stop working or become faulty, and need to be replaced. In this guide, we’ll walk you through the process of changing the pressure gauge on your Hayward pool filter.

What is a pressure gauge in a pool filter?

A pool filter is a device that removes dirt, debris, and other impurities from the water. The filter uses a pressure gauge to measure the pressure inside the filter tank, indicating when it’s time to clean or backwash the filter. The pressure gauge works by measuring the difference in pressure between the clean side of the filter and the dirty side.

Why change the pressure gauge on your Hayward pool filter?

As mentioned earlier, the pressure gauge measures the pressure inside the filter tank, which helps the pool owner determine when to clean or backwash the filter. If the gauge is faulty or not working correctly, it can be challenging to maintain the filter and pool properly. Replacing a faulty pressure gauge will ensure that the filter is working appropriately, and you can take the necessary measures to keep the pool clean and safe.

How often should you replace the pressure gauge?

The life expectancy of the pressure gauge on your Hayward pool filter may vary depending on the filter type, usage, and the chemical balance of the pool. However, we recommend replacing the gauge every one to three years to ensure it is in good condition and working correctly.

Tools and materials needed to change a pressure gauge on a Hayward pool filter

Changing the pressure gauge on your Hayward pool filter is relatively easy, and you don’t need any special tools. Here are the tools and materials you’ll need for the job:

- New Hayward pool filter pressure gauge

- Wrench or pliers

- Teflon tape

Step by step guide to change a pressure gauge on a Hayward pool filter

1. Turn off the pool pump

Before you begin, make sure to turn off the pool pump to avoid any accidents or injuries. Also, make sure that the filter has not been running for at least 30 minutes to allow the pressure to drop.

2. Locate the pressure gauge

The pressure gauge is usually located on the top of the filter tank, near the pressure release valve.

3. Remove the old pressure gauge

Using a wrench or pliers, carefully unscrew the old pressure gauge from the filter tank. It may be a bit tight, so be careful not to damage the threads.

4. Clean and prepare the threads

Once you have removed the old pressure gauge, clean and dry the threads on the filter tank where the new pressure gauge will be installed. Make sure to remove any debris or dirt that may prevent the new gauge from sealing correctly.

5. Install the new pressure gauge

Wrap some Teflon tape around the threads of the new pressure gauge, and carefully screw it into place on the filter tank. Tighten the gauge firmly, but don’t over-tighten it.

6. Test the new pressure gauge

Turn on the pool pump and check the new pressure gauge to see if it is working correctly. It may take a few minutes for the gauge to settle, and the pressure to stabilize.

In conclusion, changing the pressure gauge on your Hayward pool filter is a straightforward job that can save you time and money in the long run. By following these easy steps, you’ll know how to maintain the filter and keep your pool clean and sparkling all summer long.
