What is a Pool Filter?

Pool Filters are used in swimming pools. It is a device that cleans the pool water by removing debris and dirt from it. Pool filters can be of three types: cartridge, sand, and diatomaceous earth (DE).

Cartridge filters make use of cartridges to catch debris. These are big sheets of polyester cloth or paper folded accordion-style which are fitted into the filter housing unit. They have a high flow rate, but they need frequent cleaning as they get clogged easily with dirt and leaves.

Sand filters use sand to trap debris. The sand is usually silica, which is a very fine type of sand. It is layered in the filter tank and works by trapping the dirt and debris in the pores of the sand. Sand filters have a lower flow rate than cartridge filters, but they don’t need to be cleaned as often.

Here are some of the most common signs that to sand filter

The water turns cloudy

One of the most obvious signs that your pool filter is bad is if the water turns cloudy. A pool filter’s primary purpose is to keep the water clean and clear, so if the water is anything but that, it’s a good indication that something is wrong.

A Slow Sand Filter

A Slow Sand Filter is perfect for swimming pools that have begun to look cloudy or unclear. This type of filter can become clogged over time, even if it seems to be running correctly. Test the water chemistry and check the backwash valve before changing out the pool filter sand.

Broken or Bad Laterals

Broken or bad laterals on the sand filter will cause the sand to return to your pool. If this is the issue, then you might need to prepare for some labor. To check if it’s bad, you need to remove all of the media from the pool filter.

If it’s broken or bad, then it’s a quick task to replace it. The hardest part is removing the media so that you can get at it. You can also consider checking out your air relief tube. This part is much easier to get at and can often be the cause of your sand coming back into the pool.

Leaking multiport valves

The multiport valves are used to control the flow of water through your sand filter. They’re located on the side or top of the filter, and they’re attached by way of a spider gasket. The spider gasket is what controls how much water goes through each port, so if it becomes loose or twisted, it can cause issues with these valves.

Dirty Sand Filter

The dirty sand filter solves the sand filter problem. If you notice a shorter backwash cycle, you should check whether the sand filter is clean or greasy. If your filter is dirty or greasy, don’t be surprised if it looks like sandy lard. In this case, water does not pass through the sand filter media. Instead, you should create a channel next to the filter and then return it to the pool. Backwashing can clean the filter, but if this problem persists, it’s time to replace the sand.

Tank Failure

A tank failure can be a serious problem, and it’s important to know what to do if it happens. One common cause of a tank failure is a valve closure after the filter on the backwash or return lines. If the pressure begins to rise when you turn on the pump, you should shut it off as quickly as possible.

Another potential issue is a busted tank seam, which is more likely to happen with cheaper tanks.

Conclusion

If your sand is a bit cloudy, then it’s probably time for a cleaning. Sediment naturally accumulates in your sand over time, especially in pools with sand filters. If it’s cloudy, give it a good cleaning. If it’s dirty, hire an inground pool installer to clean your sand filter for you.
