advice on new soak away for cesspit please?
I’m putting in a new soak away pipe for my ces pit as the old one is blocked, i’m digging in about 25 metres of perforated pipe but need to know what is the best size of stone to put around the pipe to form the soak away? the pipe is 80mm and has small slots around it along it’s whole length.
What is usually used here is called No. 1A round stone, but you don’t sound like you are in the U.S., so call it pea gravel. It is about 1/4 to 1/2 inch (6 to 12 mm) diameter low-carbonate washed stone.
I work for a company that designs systems like this.
Buy a few bags of 20mm chipping, dig a deep hole – 1mX1mX1/2M deep. and pour bags in.
