1. Check if the return valve is open
The first step is to check if the return valve is open. If the valve shows a "-", it means it is open. If the valve shows a "+", it means that the valve is in a closed state.
2. There is air inside the pipe causing air resistance
If there is air inside the geothermal pipe, it will cause air resistance. In this situation, you can open the air valve. The opening time is about 1 hour to allow the air inside the tube to be completely expelled, thereby solving the air resistance problem.
3. The filter is clogged with sediment
If there is sediment in the filter, it will cause blockage in the return water pipeline. You can remove and clean the filter yourself to restore smooth water flow in the pipeline, thereby solving the problem.
4. Too much silt in the pipeline
There are also certain impurities in tap water, and over time, there will be silt in the pipes. If there is too much silt, it will cause the water flow in the pipeline to slow down. You can clean it yourself, or hire a geothermal cleaning company to clean the pipeline.
5. Insufficient return water pressure
The return valve has been opened, the pipeline has been vented, and the inside of the pipeline and filter have been cleaned. If this still doesn't solve the problem, it should be due to the low return water pressure. In response to insufficient return water pressure, a circulating pump can be installed to increase water pressure and solve the problem.
