What Should Your Pool Filter Pressure Gauge Read?
Your pool filter pressure gauge is the vital sign monitor for your entire circulation system. A quick glance tells you if everything is running smoothly or if maintenance is urgently needed. But what number should you be looking for?
The normal operating pressure for a clean pool filter typically falls between 10 and 20 PSI. However, the most important number is your system’s unique “clean pressure.” This is the reading you note right after a complete filter cleaning or backwash. Any significant deviation from this baseline signals it’s time for action.
Understanding Your Gauge’s Readings
A pressure reading 8-10 PSI above your clean baseline almost always means your filter is dirty and needs cleaning or backwashing. This high pressure strains your pump and reduces filtration efficiency. Conversely, a reading below your clean baseline often indicates a problem on the suction side, like a clogged pump basket or skimmer, or a blockage before the pump.
Why Correct PSI is Critical
Maintaining the correct pressure range ensures crystal clear water, optimal chemical distribution, and protects your pump from damage. Ignoring a high PSI can lead to blown filter components, while low pressure often means poor water flow and ineffective cleaning.
Common Pressure Gauge Questions Answered
Q: My gauge reads zero. What’s wrong?
A: This usually indicates a major blockage before the pump, an empty pump basket, or a faulty gauge. Check the pump lid and skimmer baskets first.
Q: How often should I check the pressure?
A: Make it a weekly habit. Check it at the same time each week, ideally when the pump has been running for a few minutes.
