The purpose of having a pool filter is to keep your pool clean of every unhealthy contamination. This cleaning process involves passing water through the pool filter and returning it to the pool. The filter removes the debris during this process and stores them in a container making the water clean. Over time the filter stores lots of air which causes high pressure inside the filter.
To remove this air, a pool owner has to open the air bleed tune which lets out the air slowly relieving the filter of the pressure. Most owners do not know where the air bleed tune is located or how to relieve pressure from the filter. We’re going to look at the cause of air in the filter, and how to bleed air from the pool pump and sand filters.
What Causes Air to Get into the Pool Liner?
The main cause of air getting into the pool line/filter is the ignorance of the owner and the negligence of minor issues which turn out to become major issues with the pool filter. Every pool owner should take note of these minor issues and fix them before they blow out of proportion.
- A crack in the pump lid surrounding can let air leak into the filter pump. You must always check the pump lid and its surrounding for any cracks or overstretched rings.
- An improper water level is another cause of this problem. When the water level becomes too low the skimmer begins to gulp air. Make sure the water level is always above the required level.
- A Bad/broken plumbing is another reason for air getting into the sand filter. Always observe your pool plumbing connection.
- Also, check for cracks in the skimmer because they’re another cause. These cracks usually occur when the skimmer relaxes with time which would cause some gaps to develop around the skimmer putting pressure on it to crack.
How to Bleed Air from Pool Pump?
There is actually no big deal about this. To bleed your pool pump of air is something you would do frequently so you have to know the steps. The area where air is likely to be trapped is in the filter housing. To free air from the pump, you have to open a valve at the top of the filter but you need to take other steps too such as;
- Run the filter on default and take note of the pressure gauge. You should find the pressure reading to be btw 1-10 PSI anything above 10 would mean there’s pressure build in the filter.
- Keep the filter on and check on top of the filter you’ll find a small air bleed tube. Open the tube and listen for air hissing out. Keep running the filter till air ceases to come out or water begins to leak out of the bleed tube
- Close the bleed tube and check the filter pressure. Make sure the pressure is below 10 before you can turn off the engine. If the pressure is still higher than 10, allow the filter to run and repeat the bleeding process.
How to Get Air out of Pool Lines?
Have you ever tried to get air out of pool lines and you found it difficult? To remove air from pool lines, you have to pump water through the lines to push out the air. Having air in the lines will stop the pump from drawing water to purge the air so you have to flush the air out for the pump to function properly. To pump out the air,
- Turn off the pump and the heater. If you make use of a pool cleaning pump, also turn it off.
- Open the pump valve by turning the filter container counterclockwise. Open the drain valve and shut off the skimmer valve.
- Open the pump strainer box cover to check the water level. If the water basket is empty, fill it with water.
- Check the gasket of the pump cover for cracks before lubricating the gasket and reinstalling it into place. Cover the pump tightly and set the multiport valve to filter settings.
- Put on the pump and gradually ease the skimmer open. Bubbles would be discharged as air is pumped into the pool. Let the pump run till water starts coming out of the bleed valve. Shut off the engine and return the valve back to the place. Put on the pump that is used in pool cleaning and also the pool heater.
Follow these steps carefully and you will know how to get air out of sand filter and pool lines. Spare time to observe the pool pump and its surroundings for cracks so they can be repaired to stop air from entering the pool lines. Now you’re a pro in getting air out of pool lines.
