why do you need to backwash a pool filter

Introduction:

Swimming pools are an excellent source of entertainment and relaxation during the hot summer months. Maintaining a pool, however, requires a considerable amount of upkeep. The pool filter is an essential component of the pool system, and to get the most out of your pool, it's essential to maintain the filter. Backwashing the pool filter is one of the essential maintenance procedures that every pool owner should know. In this article, we will be discussing why it is necessary to backwash a pool filter.

What is backwashing, and why is it Essential?

Backwashing is a cleaning process that involves reversing the flow of water through the pool filter. This process flushes out accumulated dirt, debris, and other contaminants that are trapped within the filter. Without backwashing, the filter's pores can become clogged, making it less effective in filtering the pool water. Backwashing is crucial for maintaining good water quality and circulation within the pool system.

Subheading 1: Benefits of Backwashing

Backwashing your pool filter regularly offers several benefits, including:

1. Improved water circulation: Clogged filters hinder water circulation in the pool. By backwashing, you assure that the water can flow freely and allows the pool to function correctly.

2. Enhanced filtration capability: Backwashing removes trapped debris, which ensures that the filter can continue to capture dirt effectively, preventing it from building up on walls and floors of the pool.

3. Reduced chemical costs: If the pool's water is greater than 2 ppm, it could lead to a significant amount of chemicals being used. If your filter is clogged, it will reduce the effectiveness of the chemicals, and you'll end up using much more than necessary.

4. Save money: Regular backwash helps to prolong the lifespan of your pool filter. The filters' lifespan can last up to two years, depending on how often they are backwashed and other factors.

Subheading 2: When to Backwash?

Knowing when to backwash is equally important as knowing how. Below are a few signs that indicate it’s time to backwash your pool filter.

1. Increased pressure on the filter gauge: A significant amount of dirt and debris can quickly accumulate in the filter.

2. Water circulation issues: If the water isn't circulating properly, it could mean that the filter is clogged.

3. Discoloured water: Discoloured pool water could be an indication of inadequate filtration.

4. When starting up a pool: When starting up a pool after winter or long term shutdown, the filter needs backwashing.

Subheading 3: How to Backwash?

Backwashing your pool filter is a relatively straightforward process. Below are the basic steps:

1. Turn off the pump motor and move the backwash valve handle to the backwash position.

2. Turn on the pump motor and let it run for 2 to 3 minutes.

3. Turn off the pump motor and shift the backwash valve handle to the rinse position.

4. Turn on the pump motor and let it run for 30 seconds.

5. Turn off the pump motor and position the backwash valve handle back to the normal filter setting.

6. Turn on the pump motor and continue your regular pool filtration cycle.

Subheading 4: Importance of Professional Pool Maintenance

While backwashing is a necessary part of pool maintenance, it's essential to keep in mind that pool maintenance goes beyond just this. Seeking the help of a professional pool maintenance company- a trained staff- can provide you with a more thorough clean, address potential issues before they become severe problems.

Subheading 5: Conclusion

Keeping your pool filter clean through backwashing is one essential step in maintaining your pool. By regularly backwashing your pool filter, you'll not only improve your pool's water flow and filtration, but you'll also reduce chemicals needed — giving you a cleaner and healthier swimming environment. It is recommended to have a professional pool maintenance company regularly service the pool to maintain optimal pool conditions.

----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.
---Poolking has a professional Quality Control team to guarantee each product is 100% inspected before packing. For example when the filter inner tank comes out, they will make a first water testing before bobbin wounding. After installation all the connections or manhole & sightglass, they will make the second water testing. During the packing procedure, QC team will inspect all the details like wounding, neck, internal resin and so on to make sure no leaking and without flaw.
