I dug up my leach bed drain, just because, I noticed the clean out, was showing it was draining slow. I also found out the leach bed was installed, without gravel underneath. There also isn’t a distribution block installed, and only one section of leach beds, about 7 4 ft sections in a straight line put in. About 20 years ago. When they dug to install the leach bed they said there was constant ground water coming up so they just put leach bed in over top the water and covered it up. I noticed when uncovering the end of the leach bed, there is sitting water inside the bed itself with a bunch of sand it seems to be draining out the holes on the side of the leach bed but barely moving through the actual drain hole, out the bed. I don’t have the money to have a pro come and do anything. Note: there’s no above groundwater sitting anywhere just under the ground beside and in leach bed . Any ideas ???
