Why Won't My Pool Filter Backwash?

If you're a pool owner, you know the importance of keeping your pool clean and properly maintained. One of the key steps in maintaining your pool is by regularly backwashing your pool filter. But what happens when your pool filter won't backwash? Here are some possible reasons why and what you can do to fix the problem.

1. Clogged filter

If your pool filter won't backwash, the first thing you should check is whether your filter is clogged. A clogged filter can cause blockages in the system and prevent proper waterflow. To fix this problem, you'll need to clean your filter. Depending on the type of filter you have, this could involve removing the filter's cartridges or backwashing your sand filter.

2. Broken valve

Another possible cause of a pool filter that won't backwash is a broken valve. The valve is responsible for controlling the water flow through the filter and other pool equipment. If the valve is broken, you may need to replace it. This is a job best left to a professional, as it involves disassembling and reassembling your pool's plumbing.

3. Damaged pump

A damaged pump can also cause your pool filter to stop backwashing. The pump is responsible for pumping water through the filter and other pool equipment. If the pump is damaged or malfunctioning, it won't be able to push water through the filter and backwash it. If you suspect your pump is damaged, contact a pool professional to have it repaired or replaced.

4. Clogged impeller

The impeller is the part of the pump that moves water through the filter and other pool equipment. If the impeller is clogged, it won't be able to move water through the filter and backwash it. To fix this problem, you'll need to disassemble your pump and clean the impeller. This is another job best left to a professional, as it involves working with the internal components of your pool's plumbing.

5. Wrong valve setting

Finally, it's possible that your pool filter won't backwash because the valve is set to the wrong position. Make sure that the valve is set to the backwash position before attempting to backwash your filter. You may also want to check the manual for your pool equipment to ensure that you're using the correct settings.

In conclusion, a pool filter that won't backwash can be frustrating, but there are many possible causes and solutions. By checking the filter for clogs, inspecting the valve, and ensuring that your pump and impeller are working properly, you can resolve most issues. If you're unsure of what to do, always contact a professional pool service to ensure that your pool is properly maintained and clean.

----It is best to replace the silica sand of sand filters every 1-2 years for the following reasons:
a During backwashing, the filtration bed volume will expand upwards by 1.2 to 1.3 times. The water flow will drive the filtration layer to flow up and down, causing the filtration material particles to collide with each other. Backwash will let the small sand evacuate.
b.Some silica sands will be welded when the acid and alkali are changed due to insufficient purity;
Therefore, the longer the time, the worse the filtering effect of the sand tank. Since backwashing will consume and take away some sand, we need to replace the sand in the sand tank within the specified period.
