Unclogging a toilet on a septic system usually involves taking care to not use chemicals that can harm the septic system. That said it can still usually be done by the homeowner. This is a guide about unclogging a drain or toilet attached to a septic system.
Our kitchen drain is slow. What can be used if you have a septic tank?
Has anyone with a septic tank used the soap and hot water method to unclog toilets? Would this damage your septic tank?

It works and will not harm it. In fact, most commercial products don't harm them either. Just read the label on the container.
I tried it and it worked for me. Haven't noticed any harm to septic.
Works good, I think the problems with septic tanks is:
1) under sized tank
2) single chamber tanks (2 chamber tanks are better)
3) to small of leach field, or clog up leach field
4) putting garbage down the drain that should be put in trash, or composted (These are my opinions)
I have had two different septic tanks and both were nothing but trouble. Yet other people seem to have no trouble at all. One thing that is a problem is the automatic lint filter on your washer. It flips when the washer cycle is done and the lint goes into the tank. It does not disolve and just builds up in the tank. If you have enough land to run the washer outside of the tank it helps. If not trying to filter the wash water as it drains would help.
Does anyone have any tips for unblocking a drain? It needs to be pretty natural as we have a septic tank (we don't want to kill the bacteria).
You can pour a box of baking soda down the drain and follow it up with a big pot of boiling water. If that doesn't work you can try snaking the drain.
I also have a septic tank and drain field. I have used sodium hydroxide (lye) several times without problem a could help, but who knows.
