Drain system for Grosfillex planter pot "Tokyo"

To be able to drain the huge planter pot during winter times and close the drainage in summer times I created a remix of the filter and designed the coupling myself. You can use a Gardena drip tube ("hard shell") to connect the filter with the y piece. The additional filters on top are nylon socks to prevent soil getting stuck inside the drain system.

I designed a further version with a 20 mm thread on the outside so you can connect a valve or the like to it. Let me know if someone needs it so I could upload it.
