In this video, we demonstrate why you do not need to use 4" bottom drains and 4" pipework on your pond or koi pond. We show the different flow rates of connecting pipework between your bottom drain and your filter system.
The main problem with 4" pipe is that people rarely have the correct flow rate so you will always get a build-up of debris which will lead to a blocked pipe.
Multiple 2" and 3" bottom drains will generally suit the majority of ponds however there seems to be a misconception that bigger is better. It certainly is not the case when it comes to flow rate.
Please note the flow rates are really based if your filter system is next to your pond. You will need to allow for a drop in flow for pipe distance, bends & friction. You could allow 15% as a guide. Recommend to plan your job using the minimum amount of bends possible.
