# Poolside Chat Episode #36: Is there a Minimum Filter Pressure (PSI)?

This is Poolside Chat where every week we answer your questions on how to fix and maintain your swimming pool. Poolside Chat is presented by INYOPools.com, helping pool owners find the right parts since 2001. In today’s episode of Poolside Chat, Rob and Matt tackle another common swimming pool question:
• Do pool filters have a minimum pressure ratings?

## Correcting Low Water Pressure in Your Pool System

One day you come out to look at your pool and you notice that the water flow isn’t what it used to be.

What happened and how do you fix it?

Many people equate low water flow to low system pressure. While it is true that many causes of low water pressure are due to low system pressure, low water flow can also be caused by high pressure. Pressure is typically measured at the pressure gauge on top of the system filter. This blog post will discuss causes of low water flow due to both low and high system pressure. (more…)
