I am about to start digging a hole for my sump basin. I plan on drilling some 1/4" holes all around the basin and use "River Pebbles" from Home Depot for 6" under the basin and 6" all the way around the basin.
However I have heard many say filter / landscape cloth should be used. I already have quite a bit of it and was planning on using it. But it seems many say the cloth should line the pit, then the stone, then the basin (so ground water flows from dirt, through fabric, through rock, then into basin). But other say to wrap the basin with the cloth and put it in the pit then pour in the gravel. (ground water flows from dirt, through rock, through fabric, then into basin).
Which method is best? Having the fabric between the dirt and rock sounds good because it would keep any silt from getting into the rock. Having it wrapped around the basin seems easier and keeps anything (including smaller rocks) from getting into the basin, but I think it would be possible for silt to clog the fabric over time and prevent water from getting in the basin.
