Package includes:
1 x self-priming pump
Note:
1. This is a product with backflow valve.
2. The engine still does not stop running, even if the water outlet is blocked, but the backflow valve is opened and in this situation water circulates in the pump.
3. This type of product can be used on occasions where there is a low demand for energy saving.
4. Please allow 1-3 cm error due to manual measurement. Thank you for your understanding.
