The pool filter is part of the pool circulatory system, but is often of little value. There are not many moving parts in the filter and it also does not use electricity but there is pressure. There is a pressure gauge on each pool filter. Knowing how to interpret a pressure gauge reading provides a sense of the operation of a pool system in general.
What is a pool filter pressure gauge?
A pressure gauge is a metering pool filter that works well specifically for water applications. This is a small measurement with a pointer at the top of the filter that controls the pressure in the pool system. A typical pressure gauge for a pool is 0 Bar / PSI (pounds per square inch) up to a maximum reading of 4 Bar / 60 PSI. However, this may vary depending on the pool.
The most common pool filter pressure gauge has a Bourdon tube element. Read our pressure gauge article to learn more about how they work.
The pool filter works by passing all the water through it and stopping larger particles. So as time goes on and the pool filter does its job, the filter starts to accumulate more dirt, oil and impurities. When this happens, the water pushed into the filter passes through the filter for a longer time, increasing the tank pressure. So the pool filter pressure gauge helps you track pressure changes inside the filter to determine when the filter should be cleaned.

What is a standard sphygmomanometer?
PSI The pressure gauge will be affected by the size of the pool, the plumbing and the installation of the system so the pressure of each pool is different. Typically, measurements are made when the pool filter is first installed and everything is working as it should. In general, the filter should be cleaned once, which was 0.7 times higher than normal or the base level.
Why are there pressure changes in the pool filter?
The pressure drop on the pool filter pressure gauge indicates a problem with the water flow to the filter. Before reaching the filter, water passes through the spatula basket, pump basket, pump itself and main drain. In most cases, the blockage causes a drop in pressure. A sudden increase in pressure can mean a blockage in the filter system. The problem must be resolved by removing the blockage or thoroughly cleaning the filter.
What happens when there is air in the pool system?
Filter pressure gauges work in combination with relief valves. Volvo air relief allows trapped air to escape from the filter system. Air is easily trapped in the system when the filter is flushed again or the pump basket is cleaned. Over time, this trapped air builds up in the filter, increasing the overall pressure. Regular drain of the filter is good. Quail milk is often used whenever there is a slight increase in pressure.
Understanding these basic measurements and the purpose of the pool filter pressure gauge makes the pool clean, tidy and consistent. While sphygmomanometers usually require very little maintenance, there may be occasions. To learn more about these cases, read our information article on troubleshooting sphygmomanometers.
Frequently Asked Questions Pool Filter Pressure Gauge
What should be the air pressure on the pool filter?
It depends on the pool, but about 0.7 bar / 10 psi above the base measurement is the filter cleaning point. “To ensure the normal operation of the pool, basic measurements should be taken after cleaning and rinsing.
How can I tell if a pool pressure gauge is defective?
If it reads zero when the pump is on, the gauge is most likely broken. Swinging is another sign of a confused fracture.
Why is the pressure of the pool filter constantly increasing?
The most common cause of high pressure in the pool is a dirty filter. As filter cartridges or sand absorb the soil in your pool water, they become increasingly clogged. Clogging means that water has fewer and fewer holes in the filter medium to pass through. Must be free of particles.
