Well, this winter is really getting on my nerves now. Darn drainfield froze up on me. Anybody know of a DIY method to de-ice and get the proverbial s--t running downhill or do I have to get the expensive guy out to steam it. System is a mound type with lift pump. Line from lift pump to first cleanout is clear. Black water is currently overflowing at the cleanout and running down into the low pasture. Not the most desirable situation naturally but it's not running towards any other property or buildings and can collect and percolate in a fallow area so it's not the end of the world if I have to wait for nature to thaw it out.
