How to Change a Pressure Gauge on a Pool Filter


If you are the proud owner of a swimming pool, then you know that proper maintenance is of utmost importance. One of the essential components of a pool's filtration system is the pressure gauge. This gauge measures the pressure within the pool filter tank and indicates when it's time to backwash the filter. Like any mechanical part, gauges eventually wear out and need to be replaced. So, in this article, we will walk you through the process of changing a pressure gauge on a pool filter.


What You'll Need

Before we dive into the steps, let's first gather the necessary tools and equipment:


- Replacement pressure gauge

- Wrench or pliers

- Teflon tape

- A towel or cloth


Step 1: Turn off the Pool Pump

It's always important to turn off the pool pump before any maintenance work to prevent harm to yourself or damage to the equipment. Locate your pool's circuit breaker and switch off the power to the pool pump.


Step 2: Release Pressure from the Filter

Next, relieve the pressure from your filter by using the pressure release valve positioned on the filter. This valve is essential to prevent pool filter tanks from over-pressurization, which could result in damage to the filter or its components.


Step 3: Remove the Old Pressure Gauge

Using a wrench or pliers, loosen and remove the old pressure gauge from the pool filter. Usually, the gauge is located on the top of the filter's tank. Unscrew the gauge counterclockwise to remove it from the tank fully.


Step 4: Apply Teflon Tape

Wrap Teflon tape around the threads of the new pressure gauge in a clockwise direction. Make sure you wrap up to the edge of the gauge's threads, and don't wrap over the edge. Doing so ensures a tight seal and prevents leaks.


Step 5: Install the New Pressure Gauge

Screw the new pressure gauge into the opening left by the old gauge. Make sure you hand-tighten the gauge as much as possible to prevent over-tightening. Tighten to the right and do not force the gauge in.


Step 6: Turn on the Pump

Once the new gauge is installed, you can turn the pool pump back on. Check your new pressure gauge to make sure it displays the proper pressure reading. Monitor the gauge to ensure that it maintains standard pressure.


Final Words

Changing out your swimming pool's pressure gauge may seem like a small part of routine maintenance, but it's a critical task that ensures proper filtration and extends the life of your pool filter. With this guide, you won't need to hire an expert every time you need to change the gauge. Now you can do it yourself with ease. Happy swimming!
