Spa And Pool Filter Maintenance 101: What NZ Pool Owners Should Know

Having a pool on your property can be a great source of both fun and relaxation, but you also have responsibilities as a pool owner that shouldn’t be ignored. For example, your pool filter helps to keep your pool sparkling and crystal clear, and it keeps your water safe to swim in. You should maintain your pool filter regularly to promote water cleanliness, efficiency and the longevity of your filter itself. 

If you notice that your filter is blowing back dirt, leaking, clogging or otherwise isn’t doing its job as it should, then that’s a bad sign that there’s something wrong with it. Properly maintaining your filter regularly, even if you aren’t noticing any active problems, can prevent these issues and keep your pool nice and inviting.

Understanding Spa And Pool Filters: Why Filters Are An Essential Part Of Any Pool Setup

Pool filters keep the water clean and safe by removing dirt, debris and unhygienic particles. They can also prevent algae growth and ensure efficient water circulation, promoting water cleanliness. Of course, when you head out to enjoy your pool, you want to see inviting, clear water – not swampy green water. 

There are two main types of spa and pool filters that are used in New Zealand:

  • Sand Pool Filters. Sand pool filters are the most commonly used type of filter in New Zealand. They’re durable, robust and low-maintenance, making them a great choice for any kind of pool owner who wishes to keep their water clean and safe. These sand filters can be filled with different media options for enhanced filtration.
  • Cartridge Pool Filters. Cartridge filters, on the other hand, filter finer particles than sand filters. They also require less water flow and are more energy-efficient than standard sand filters. Cartridge filters are ideal for tight spaces and are simpler to maintain.

Cleaning Your Pool Filters Effectively

How should you clean your pool filters? It’s vital to set up a good maintenance schedule to follow so that your pool system is consistently cleaned, preventing potentially dangerous and unpleasant issues. 

Cleaning Your Sand Filter. A key part of cleaning your sand filter is backwashing. Backwashing is the process of reversing your water flow, directing the flow into the pool’s filter. This flushes the filter medium and then expells the polluted water.

After backwashing is completed, be sure to rinse your filter to prevent debris re-entry. Then, check the sand condition for signs that it needs to be replaced. If your sand is clumping, this could reduce filtration efficiency. 

How frequently you need to clean your pool filter will strongly depend on how frequently you use it. In general, it’s recommended to clean your spa or pool filter at least once every 1-2 weeks if you use it often or once every month if you use it less frequently.

It’s generally recommended to replace your sand every 3-5 years or so, but the frequency of replacing it will depend on your situation. You should check your sand when you maintain your filter to see if it should be replaced. 

Cleaning Your Cartridge Filter. You can rinse your cartridge with water, focusing on each part so that it is thoroughly cleaned out. A filter cleaning solution can also be used for a deeper clean; if you choose a cleaning solution, it’s best to follow the manufacturer’s instructions to avoid misuse. Rinse the filter thoroughly before reinstalling it.

To avoid damage to your cartridge filter, use an appropriate amount of water pressure and handle your filter with care. 

It’s recommended to clean your cartridge filters once every 4-6 weeks or after heavy usage. Many pool owners replace their cartridge filters once every 3-5 years.

Regardless of the type of pool filter you choose and how long you’ve used it, you should still look for signs to replace it whenever you maintain it. Keep an eye out for concerning problems like reduced water flow despite cleaning, visible damage and persistent cloudy or dirty water even after you clean it. 

To be safe, check the manufacturer’s recommendation for cleaning and replacing the particular filter you use.
