Had Doug fix a septic system that was improperly installed and couldn't be serviced. He replaced the vault risers, repaired discharge pipe plumbing, repaired flush line end caps and repaired inlet pipe to tank. He had a helper with him. They arrived a little late and worked the full day. All looks better and seems OK after 1 week. I'll need to rake everything smooth as they did some backhoe work. The only negative was that they left all the trash for me to figure out what to do with. 2 very heavy concrete covers and three old plastic vault risers. No idea what / how I'm going to dispose. At the end, I asked him about them and he said I could plant flowers in them or use them to hold up a deck umbrella. Hmmmm. Nice excuse. ha ha. Next time, I'll make sure that trash disposal is part of the deal. I would use him again, including haul off of the trash.
