Understanding the Components
An Intex sand filter system comprises several key components working in harmony to deliver effective filtration. The filter tank houses the sand media, acting as the primary filtration chamber. The multiport valve controls water flow direction, enabling functions like filtration, backwashing, rinsing, and waste.
The pump circulates water through the system, providing the necessary pressure for filtration. A strainer basket within the pump prevents large debris from entering and damaging the filter. O-rings create watertight seals, preventing leaks at connection points.
The pressure gauge monitors filter pressure, indicating when backwashing is required. Finally, the sand media itself, typically silica sand, is the core filtration element, trapping particles as water passes through. Familiarizing yourself with each component’s function is vital for proper maintenance and troubleshooting.
Filter Types and Sizes
Intex sand filters are available in various types and sizes to accommodate different pool volumes and filtration needs. Common types include those designed for above-ground pools and larger, more robust models for in-ground installations. Filter size is typically indicated by its flow rate, measured in gallons per minute (GPM), and the amount of sand it can hold.
Smaller filters, like those with a 1,000 GPM flow rate, are suitable for smaller pools (under 10,000 gallons). Larger filters, with flow rates of 1,500 GPM or higher, are designed for larger pools (over 15,000 gallons). Choosing the correct size ensures efficient filtration and prevents strain on the pump.
Consider your pool’s volume and pump’s capacity when selecting a filter. An undersized filter will struggle to keep the water clean, while an oversized filter may be unnecessarily expensive.

Backwashing Procedure – Step-by-Step
Backwashing is crucial for removing accumulated debris from your Intex Sand Filter, restoring optimal flow and filtration. Begin by turning off the pump to prevent damage. Next, rotate the multiport valve to the “Backwash” position – this reverses the water flow.
Ensure the waste line is properly connected and directed to a suitable drainage area. Turn the pump back on and allow it to run for 2-3 minutes, or until the water in the sight glass clears.
Turn off the pump again, and return the multiport valve to the “Filter” position. Finally, restart the pump and monitor the pressure gauge; a normal reading indicates successful backwashing. Regular backwashing, based on pressure increases, maintains efficient filtration.
Remember to prime the pump after backwashing if necessary, ensuring proper water levels for optimal operation.
Sand Replacement Schedule
Maintaining optimal filtration requires periodic Intex Sand Filter sand replacement. While sand itself doesn’t truly “wear out,” it becomes less effective over time due to accumulated oils, minerals, and debris that backwashing cannot fully remove.
Generally, sand should be completely replaced every 3-5 years, depending on pool usage and water chemistry. If you notice consistently cloudy water despite proper backwashing and chemical balance, or a significant decrease in filter performance, it’s likely time for a change.
Consider replacing the sand after a particularly heavy algae bloom or if you’ve experienced prolonged periods of unbalanced water. Use only filter-grade silica sand, following the manufacturer’s specifications for quantity and grain size.
Proper sand replacement ensures continued efficient filtration and a sparkling clean pool.
Cleaning the Filter Basket
Regularly cleaning the Intex Sand Filter pump basket is crucial for maintaining optimal water flow and preventing strain on the pump. This basket catches leaves, hair, and other large debris before they reach the filter, extending the lifespan of the sand and improving overall filtration efficiency.
Inspect the pump basket at least weekly, or more frequently during periods of heavy use or after storms. To clean, turn off the pump, release any pressure, and carefully remove the basket lid. Dispose of the collected debris and rinse the basket thoroughly with a garden hose.
Ensure the basket is properly seated and the lid is securely fastened before restarting the pump. A clogged basket significantly reduces water flow and can lead to increased pressure, potentially damaging the pump.
Consistent basket cleaning contributes to a healthier and more enjoyable pool experience.
Troubleshooting Common Issues
Diagnosing problems like low flow, high pressure, or sand leaks is vital; this section offers solutions for typical Intex Sand Filter malfunctions, ensuring quick resolutions.
Low Water Flow – Causes and Solutions
Reduced water flow in your Intex Sand Filter system can stem from several sources, demanding systematic investigation. A primary culprit is often a clogged filter basket, restricting water intake to the pump; regular cleaning is crucial.
Additionally, vacuuming devices attached to the system can significantly diminish flow and elevate pressure. Disconnecting these devices and observing the pressure gauge is a simple diagnostic step.
Furthermore, ensure all valves leading to and from the filter are fully open. Partially closed valves impede water circulation. If the pump basket isn’t primed with water, it can struggle to initiate flow, requiring manual priming.
Finally, a partially clogged sand bed itself can restrict flow; backwashing is the solution. Inspecting the lines for obstructions is also recommended.
High Pressure Readings – Identifying the Problem
Elevated pressure readings on your Intex Sand Filter gauge signal a restriction within the system, demanding immediate attention. The most frequent cause is a dirty or clogged filter sand bed, hindering water passage. Backwashing the filter is the initial corrective action to alleviate this pressure.
However, if backwashing doesn’t resolve the issue, investigate the filter basket for debris accumulation. A clogged basket restricts water flow, increasing pressure. Similarly, vacuum attachments can contribute to higher readings; disconnect them for testing.
Inspect all valve positions, ensuring they are fully open. Partially closed valves create resistance. A less common, but possible cause, is a blockage within the piping itself, requiring inspection and removal of any obstructions.
Consistent high pressure can damage the filter, so prompt diagnosis is vital.
Sand Leaking from the Filter – Diagnosis and Repair
Discovering sand escaping from your Intex Sand Filter indicates a compromise in the filter’s sealing integrity.
