Excerpt from the State of Michigan Code-
“Disposal tile should be laid so that a 12-inch earth cover is provided. Under no condition shall the tile line be laid below the groundwater level.
Notes
Mich. Admin. Code R. 325.423‘“

One reason why septic systems (field drains) are often laid literally on top of the ground and then covered over. The “frost line” for our Code of Construction is 42”! As with trapping never believe everything is the same everywhere!

Different inspectors I guess, what do you guys do if your lateral comes out below basement floor say 6' or 8' below grade?

In the basement below grade you would need a lift pump.

X 2

Yeah, no way that would work here either Lug. Lines would be in the water table most years. As well as being way too deep for evaporation.

Soooooooooooo 330 are you still froze?

I think that's why code calls for relatively shallow drain fields and only topsoil (no non-organic subsoil) over the crushed stone, for evaporation.

Vast majority of new sewers are mounds in this country. I typically quit mowing ours in the fall for some cover for winter.

The frost line for building in PA is 36" below grade. You'd never get an in-ground system passed here if you put it that deep or deeper.



Your ground freezes 36" in deep? I know you guys have colder for longer than we do but dang. 330 don't have a clue how deep your lines are . BUT I can tell you one thing. IF you have caps off and air is going to be able to get in and out of your field plus it's really cold you are asking for problems...

330 you got an easy fix. Get you a big tub to boiling on your turkey burner. When it starts boiling just pour it down each of those cleanouts (you call them inspection pipes) Put the cap back on to keep the heat in . EASY FIX

I've never seen frost anywhere near that deep, that's just the building code minimum that footers have to be located at.

I've seen those so called inspection pipes on drainfields. Not sure what their purpose is, sometimes they're capped sometimes not and they are full of dirt. I don't think they're attached to the drain field line at all but just put there to mark the lines.

Seems to be working better since I covered all the holes

Tank is low level


I understand the sumac and two trees down there need cut.

i cannot find a pvc cover for the cement tank lid

for now it's heavy ml. plastic x4 thickness ans a hose clamped.


What if I ran my Turbo heater with ducting from the heater necked down into the Tank's 7" hole???

I wish I could find one like this in my Area

Far East Central , Mn.

Thanks for trying Ken

What would happen if I used ducting from my diesel turbo heater down into the Tank itself?

How can you tell that those lines are frozen if they’re under ground?

I looked down the clean outs and could see it frozen

I still want to know what would happen if I used seven inch ducting and came off my turbo heater and necked it down into the tank?

You had the tank pumped so it will work fine until the tank fills. There's got to be steam thawers in your area, the same guys that steam ice dams on roofs usually can steam sewer lines.
