How To Install A Pressure Gauge On The Water Filter?

Installing a pressure gauge on a water filter is essential to maintaining the system. The pressure gauge will monitor the pressure in your filter, ensuring that it does not become too high or too low. This can help you identify potential problems with your filter before they become more serious.

Installing a pressure gauge on a water filter is done by attaching a fitting to the side of the filter, which will connect to the pressure gauge. Make sure you select a pressure gauge with a range appropriate for the water filter. Attach the dial face of the pressure gauge to the case, and you are ready to measure the pressure in your system.

A pressure gauge is a device used to measure the internal pressure of a fluid or gas. It displays the output in terms of pressure and can be used to control flow rate, tank levels, and more. You can install a pressure gauge on a water filter to measure the filter’s pressure. This helps you know how much pressure is in the filter and how it may affect your water supply.

The filter inlet or outlet is the best place to install a water pressure gauge. This will ensure an accurate reading of the water pressure passing through your filter system. Also, use locking pliers and Teflon tape when securing the gauge to prevent it from vibrating loose over time due to high water pressure.

Buy a suitable pressure gauge: Before installing it, ensure it is suitable for your water filter. Check whether the size and type of connector fit with the filter and whether it’s compatible with your water source.

Locate a suitable mounting surface: The pressure gauge should be close to the water filter for easy access and monitoring. You will need a flat surface like wood or metal to mount the pressure gauge. Make sure to use appropriate screws and bolts that can hold the pressure gauge firmly in place.

Turn off the water source

Turn off the water source: Before installing the pressure gauge, always turn off the water source.

Relieve any built-up pressure: Before installing the pressure gauge, it is essential to relieving any built-up pressure from the system. To do this, open a faucet downstream of the filter and allow water to flow out for several minutes until no more air hisses or spurts out.

Cut the tubing
Cut the tubing

 Cut the tubing: Cut the tubing to a length that will reach from the pressure gauge’s inlet port to your water filter’s outlet port. Leave at least one inch of extra tubing if you need more slack. Use a sharp knife, scissors, or a small hacksaw to get an even cut.

 Install the T-fitting

 Install the T-fitting: Attach the T-fitting. The T-fitting should be connected to the output line from the sediment filter or, if applicable, the carbon block filter. Be sure both outputs of the tee are facing in opposite directions and that no threading is exposed before you move on to attaching the pressure gauge.

Secure the Pressure Gauge: Once the T-fitting is attached, you can attach the pressure gauge to one of the outputs on the tee. Use thread sealant (e.g., teflon tape) and tighten with a wrench or pliers. Make sure that all connections are secure to ensure proper pressure readings.

Connect the Water Line: Attach the water line to the open output of the T-fitting. Again, ensure all connections are secure to prevent leaks and ensure proper pressure readings. Once everything is connected, you can turn on the water supply and test for the proper functioning of your pressure gauge.

Check for any leaks

Check for any leaks: To ensure the installation is successful, test for any leaks after setting up the pressure gauge. You can do this by disconnecting the plumbing from the water filter and turning on the water supply. Wait for a few minutes to see any leaks or drips visible near where you installed the pressure gauge.

How Does Pressure Gauge Work?

Pressure gauge works by measuring fluid pressure in a pipe or container. The gauge uses an internal diaphragm to detect the pressure, which is then displayed on a scale. A typical pressure gauge consists of three main components: the case, the bourdon tube, and the dial.

  • The case houses all the other parts and is designed to protect them from the environment.
  • The bourdon tube is a curved tube that is sealed at one end and attached at the other end to the case. When pressure is applied to the inside of the tube, it causes it to straighten out, which in turn moves a pointer on the dial face. This change in position indicates how much pressure is present in the pipe or vessel.

Stem mounting pressure gauges, sometimes referred to as direct mount pressure gauges are designed to be mounted directly onto the sensing element of a water filter. This gauge type is used when the installation requires very little space and can accommodate the gauge’s smaller size. Compared with other mounting types, this method offers a more reliable and accurate pressure reading since it is not affected by the filter’s vibration or rotational movement.


Do pressure gauges need to be upright?

Yes, pressure gauges should be installed upright and not on their sides. This will ensure that they can accurately measure the pressure of your water filter. Also, remember that a pressure gauge must be mounted securely to avoid movement or vibration, which could lead to inaccurate readings.

Where should the vacuum gauge be mounted?

Once a pressure gauge is installed on the water filter, it should be mounted to an easily accessible location that allows for regular monitoring. The gauge must also be located where it will not come into contact with corrosive liquids, such as acids or caustic cleaning solutions. It is recommended to install the vacuum gauge at least 6 inches away from any other instrumentation, such as pumps or valves.

Types of pressure gauges

The two primary pressure gauges used on water filters are differential and absolute pressure gauges. A differential pressure gauge measures the difference between two pressures, one acting on each side of a diaphragm or bellows. An absolute pressure gauge measures the absolute or static pressure in a system. It can also measure the static pressure in a sealed system.


Installing a pressure gauge on your water filter is simple as long as you have the right tools. When selecting a pressure gauge for your water filter system, it is essential to consider the application and operating environment. Care must also be taken during installation and calibration to ensure the safe operation of the system. Following these instructions, you can properly install your water filter system.
