Hi guys, any idea how to drain water from the filter please? I've taken pictures of the bottom of the housing with my phone and there appears to be some sort of drain port with a bit of a hexagon on it. However, there also looks to be a casting line running down the bowl which continues down the drain, making me think it's all one. I've tried to get an 8mm and 10mm spanner onto this hexagon to gently see if theres any movement but neither fit.
Any replies greatly appreciated.
