Quick Answer
To clean a gravity-bag filter, first, turn off the water flow, then take the filter apart, and soak it in a mixture of water and bleach. Next, scrub the filter with a soft-bristled brush to remove any debris. Finally, rinse the filter thoroughly and reassemble it.
Pre-Cleaning Preparation
Before cleaning the gravity-bag filter, turn off the water flow by closing the shut-off valve or turning off the pump. This will prevent any water from flowing through the filter while you’re cleaning it. Next, take the filter apart by removing the filter housing and any other components that make it easy to access the filter membrane.
Cleaning the Filter
To clean the filter membrane, mix 1-2 teaspoons of unscented bleach with 1 liter of water to create a cleaning solution. Soak the filter membrane in the solution for 10-15 minutes to help break down any debris or contaminants. After soaking, use a soft-bristled brush to gently scrub the filter membrane, working from the outside in to avoid damaging the membrane.
Rinsing and Reassembling
After cleaning the filter membrane, rinse it thoroughly with clean water to remove any remaining bleach solution and debris. Reassemble the filter in the reverse order that you disassembled it, making sure to securely tighten all components to prevent leaks. Finally, turn on the water flow and test the filter to ensure it’s working properly.
