I put a dry well in for my kitchen drainage to go into a 55 gallon drum i buried now its backing up some 4 years later is there a chemical soloution or will i have to dig it up?
I'm not sure what you mean. Is the plumbing getting clogged or is the barrel just getting full and backing up. Also where does the water go after it is in the dry well. Do you use it for gardening?
If the drum didn't have holes in it or have the bottom cut out, then chances are, it full and running over. Perhaps you can get a septic tank to pull the water out and then make hole in the drum so that the water will seep out.
Dry well Does having a dry well mean that water goes straight from the house into the surrounding yard, or through to a drainage ditch or pipe? I've never heard of these, but they sound kind of unhealthy to me, too. If chemicals are involved, they sound dangerous.
