How do I remove the inlet and outlet sieve and insert the plug when I want to change the filter of the filter pump?

When replacing the filter filling of the filter pump, it's important that no more water is running towards the pump. Therefore, remove the inlet and outlet sieve, which you can find on the outside of the pool, in their entirety. Subsequently, place the added plug in the liner. This can be difficult because the liner doesn't leave much space. You can use a bit of Vaseline or warm the liner up with your hands, so the material gets a little more flexible. In addition, you can use a bit of force and press and turn, then we're sure it'll work.

If it's possible you can also lift the filter pump above water level. Then you won't be bothered by leaking and replacing the filter filling will go much smoother.
