Pool Strainer: What It Is and How It Works
A pool strainer, also known as a hair and lint strainer, is an essential piece of equipment installed before the pool water enters the pump. Acting as a pre-filter, the pool strainer prevents solid materials from entering the filtration system. In this article, we will discuss the function and benefits of pool strainers.
What is a Pool Strainer?
One of the most enjoyable activities during holidays and hot summers is swimming in a pool. However, no one likes swimming in a dirty pool, as pools can be a breeding ground for various diseases. Ensuring the water is clean and free from contaminants is crucial, and various pieces of equipment in the pool’s filtration process play significant roles in maintaining cleanliness.
The pool pump is the central component of the pool’s filtration system, and without it, cleaning the pool would be impossible. To ensure the pump operates correctly and to prevent potential damage, protective measures are necessary. Damage to the filtration pump can lead to significant financial losses. One such measure to safeguard and enhance the efficiency of the pump is the use of a pool strainer, installed at the water intake before it reaches the pump. The strainer collects larger particles such as hair, threads, leaves, and twigs before they can enter and damage the pump’s impeller.
How Does a Pool Strainer Work?
Pool strainers are cylindrical and contain a sieve basket inside a housing. This basket has holes measuring 3 to 4 millimeters, which prevent solids from entering the filtration pump.
The strainer has a water inlet where water enters, passes through the sieve basket that traps debris, and pre-filtered water then exits towards the pump.
In small pools, pumps often come with built-in strainers. However, in larger pools, strainers are installed as separate units at the water intake. It’s important to note that strainers can be used to protect all sensitive equipment in a pool system.
Types of Pool Strainers
Strainers come in various types based on material and capacity. Common materials include plastic, cast iron, bronze, and stainless steel. Strainers for large pools are usually made of stainless steel or steel, offering high resistance to corrosion.
The capacity of a strainer depends on the volume and flow rate of the pump. Some strainers have a viewing window to check the basket’s condition and debris level, allowing for easy maintenance.

How to Clean a Pool Strainer
To extend the life of pool filtration equipment, regular maintenance is essential to avoid damage and potential costs.
The strainer basket should be inspected regularly, especially during spring and autumn when debris accumulation is higher. If not maintained, debris buildup can reduce water flow to the pump, decreasing its efficiency.
To clean the pool strainer, first, turn off the filtration pump and close the skimmers. Next, reduce the pump pressure using the air release valve on the pump. Then, open the strainer lid, remove the basket, and wash it with a high-pressure water hose. Before reinstalling, check the basket for cracks or damage and replace it if necessary.
