billynomates666 Posted May 20, 2020 Report Share Posted May 20, 2020 Hi George The pipe will stop the sink from overflowing, providing the holes in the side of it allow water out faster than its falling from the sky. The pipe can be any length you like if you put the holes in the side, raising it above the soil level will stop the medium falling down the hole. The sink doesnt look like it has a lot of capacity? so I would tend to put the holes about half way up to give you some water reservoir capacity, much lower and you will be watering frequently, much higher and you risk anerobic conditions. Cheers and good luck Steve Quote Link to comment Share on other sites More sharing options...
