Time lapse of the construction of my garden office/studio room from timber. My aquarium hobby is growing and I decided to build a garden studio room for all my aquariums!
You need a plastic insert at the end of each pipe. Also each connector has ring which needs to be twisted clockwise to lock pipe inside. I would install small waste pipe little higher in relation to orange one as it might start to fill up or catch whatever is flushed in your toilet at the beginning. Otherwise great job!
