We never recommend a pond of any size without fitting a bottom drain. Our standard bottom drain size is 100MM and our drains fit 100mm DWV pipe. This pipe is used throughout W.A. in house sewage systems. As such, it is readily available and both pipe and bends etc are relatively cheap to purchase. We use this pipe under ground from pond bottom drains to the start of the filtration unit.
For all other pipework we use reticulation class 9. We use this pipe due to its availability, cheap cost and huge range of fittings. Most pump thread sizes can be matched to this pipe.
We stress these recommendations are for W.A. sandy soils only.
