The method of replacing waterproof mechanical seal is as follows:

First remove the fixing screw of the outlet of the submersible pump and remove the outlet, then remove the screw of the impeller. Find one end of the long square wood and put it at the bottom of the impeller. At the other end, knock down the upper end of the square wood with a hammer to pick the impeller off. Before removing the mechanical seal, remember the installation sequence of the mechanical seal. It is recommended to take photos and file. After removing the old mechanical seal, install the new mechanical seal in the correct order.
