The filter system in your pool heater is incredibly important for proper functioning. Without it, debris, dirt, and leaves can easily clog up your heater and prevent it from working optimally. Therefore, regularly checking and cleaning the filter system is crucial to keeping your pool heater in good condition.

The filter system itself consists of three main parts – the filter, the pump, and the skimmer basket. All of these parts work together to ensure clean water is pumped into your pool. As debris and other materials are pulled into the skimmer basket, they are then passed through the filter and pumped out by the pump. Therefore, it is essential to keep all of these parts working together in good condition.

The first step in checking the filter system involves inspecting the skimmer basket. It is recommended to do this at least once every 2-3 weeks. You should remove the basket and inspect it for any cracks, damage, or clogs. If there is a clog, take a pool skimmer or a hose and clear the debris from the basket. This simple action can already make a huge difference in the performance of your pool heater.

Next, clean the pump by removing the basket and clearing any debris from it. Something else to check for during this step is whether the pump is aligned and at the right height. Both of these factors can play into how well the pump operates and may need to be adjusted accordingly. It is also recommended to apply some silicone lubricant to the o-ring to keep it running smoothly.

After you’ve inspected and cleaned the skimmer basket and pump, it’s time to move onto the filter. While the filter system depends on all three components functioning well, the filter is the main body that actually cleans your pool water. Because of this, it is crucial to keep it in good working order.

If you have a cartridge filter, remove the cartridge from the filter housing and inspect it for any damage or signs of wear. As with the other parts of the filter system, it’s recommended that you clean the cartridge every 2-3 weeks to ensure proper functioning. This can be done simply by hosing the cartridge off. However, if the filter is especially dirty, you may need to deep clean it with a diluted acid solution or replace it altogether.

If you have a sand filter, cleaning it is a bit different. First, turn off the pool’s pumps and set the multiport valve to the “backwash” position. Turn the pump back on and let it run for about 2 minutes. Then, turn off the pump and set the multiport valve to the “rinse” position and run the pump for another 30 seconds. Finally, shut the pump off again and set the valve to “filter”. And viola, it’s clean!

In conclusion, regularly checking and cleaning the filter system is a crucial step to keeping your pool heater in good condition. Make it a habit to inspect the skimmer basket, pump, and filter every 2-3 weeks to ensure proper functioning. Doing so can save you from costly repairs and ensure uninterrupted summer fun.
