What Are Side Mount Sand Filters?

Side mount sand filters are an essential component in the filtration systems for large swimming pools. Unlike traditional top-mounted filters, side mount sand filters feature a design that allows them to be installed with the plumbing running from the side. This design is particularly advantageous for larger pools due to its robust construction and efficient operation.
These filters utilize sand as a filtration medium, capturing dirt, debris, and small particles as water passes through. They are ideal for commercial and residential applications, providing a reliable solution for maintaining clear and clean pool water.

How Side Mount Sand Filters Work

The operation of a side mount sand filter is straightforward yet highly effective. Water from the pool is pumped into the filter through the inlet. As the water enters, it flows through the layer of sand, which acts as the primary filtration medium. Here’s a step-by-step breakdown of the process:

1. Water Entry

The water enters the filter through the inlet pipe, where it is directed into the top of the sand bed.

2. Filtration Process

As water flows downward through the sand, particles are trapped within the sand grains. The sand's surface area and the varying sizes of the grains contribute to the efficient removal of contaminants.

3. Clean Water Exit

Filtered water then exits the filter through the outlet pipe at the bottom, returning it back to the pool, ensuring that the water is clean and safe for swimming.

4. Backwashing

Over time, dirt and debris accumulate in the sand, which can lead to reduced flow and efficiency. To restore the filter's performance, backwashing is performed, reversing the flow of water. This process dislodges the trapped debris and flushes it out, allowing the filter to function optimally once again.

Components of Side Mount Sand Filters

Understanding the key components of side mount sand filters will help pool owners appreciate their functionality and maintenance requirements. Here are the main components:

1. Filter Tank

The filter tank is typically made from durable materials such as fiberglass or polyethylene. It houses the sand and components necessary for filtration.

2. Sand

Specially graded sand serves as the filtration medium. The sand’s size and shape are designed to capture a wide range of particles.

3. Lateral Assembly

This assembly at the bottom of the filter tank allows water to exit while preventing sand from escaping. It is crucial for the filter's efficiency.

4. Valves

Side mount sand filters are equipped with multiport valves that control the flow of water in various operations, including filtration, backwashing, rinsing, and waste.

5. Pump

The pump is essential for circulating water through the filter, ensuring continuous operation and effective filtration.

Advantages of Side Mount Sand Filters for Large Pools

Side mount sand filters offer numerous benefits, making them an ideal choice for large pools. Here are some of the key advantages:

1. Efficient Filtration

The design and operation of side mount sand filters allow for efficient removal of contaminants, resulting in cleaner pool water.

2. High Flow Rates

These filters can handle high flow rates, making them suitable for larger pools where water circulation is crucial.

3. Low Maintenance Requirements

With proper maintenance, side mount sand filters can last for many years. Backwashing is a simple process that can be performed regularly to maintain performance.

4. Cost-Effectiveness

Compared to other filtration systems, side mount sand filters are relatively cost-effective in both initial investment and ongoing maintenance.

5. Versatility

These filters are versatile and can be used in various pool settings, from residential to commercial applications.

Installation Process of Side Mount Sand Filters

Installing a side mount sand filter involves several critical steps that should be followed carefully to ensure proper functionality:

1. Preparing the Site

Select a location that is accessible for maintenance and away from debris. Ensure a stable surface for the filter.

2. Connecting the Plumbing

Proper plumbing connections must be made to ensure water flows correctly to and from the filter. This includes connecting the inlet and outlet pipes.

3. Installing the Filter

Place the filter tank in the prepared location. Ensure that it is level and secure to prevent any structural issues.

4. Filling with Sand

Add the appropriate type and amount of sand to the filter tank, as specified by the manufacturer.

5. Setting Up the Multiport Valve

Install the multiport valve on the filter tank and connect the necessary plumbing. Ensure all connections are tight to prevent leaks.

6. Priming the Pump

Before starting the system, prime the pump to remove any air from the lines, ensuring optimal operation.

7. Testing the System

Once everything is connected, turn on the system to test for leaks and ensure the filter operates correctly.

Maintenance Tips for Side Mount Sand Filters

Proper maintenance of side mount sand filters is crucial for longevity and performance. Here are several maintenance tips to keep in mind:

1. Regular Backwashing

Perform backwashing every 4-6 weeks, or when the pressure gauge indicates a rise of 8-10 PSI above the normal operating pressure.

2. Inspect Components

Regularly check the filter tank, lateral assembly, and valve for any signs of wear or damage, and replace parts as necessary.

3. Monitor Water Chemistry

Maintaining balanced water chemistry can help prevent algae growth and reduce the load on the filter.

4. Clean the Pump Basket

Check and clean the pump basket regularly to ensure optimal water flow and prevent pump damage.

5. Seasonal Preparation

At the end of the swimming season, take extra precautions to ensure the filter is winterized properly to prevent damage from freezing temperatures.

Troubleshooting Common Issues with Side Mount Sand Filters

Despite their reliability, side mount sand filters can experience issues from time to time. Here are some common problems and their solutions:

1. Low Water Flow

If you notice a decrease in water flow, check for clogs in the plumbing or debris in the pump basket. Additionally, ensure the sand is not compacted.

2. Cloudy Water

Cloudy water can indicate poor filtration or imbalanced chemicals. Check the sand and consider performing backwashing or replacing the sand if necessary.

3. Leaks

Inspect all connections for leaks. Tighten any loose fittings or replace worn seals.

4. Excessive Pressure

If the pressure gauge reads too high, backwashing may be necessary. If the problem persists, check for clogs in the sand or lateral assembly.

Conclusion

Understanding the mechanics of side mount sand filters is essential for large pool owners who want to ensure clean, safe water for swimming. With efficient operation, low maintenance needs, and cost-effective performance, these filters are an outstanding choice. By following best practices for installation, maintenance, and troubleshooting, you can keep your side mount sand filter running smoothly for years to come.
