At my sister in laws house.They have septic system.Put in 1978.Few weeks ago it started giving trouble.Today it was pumped out fully.Now the toilets/shower/etc are backing up.Will call contractor, but it's a small town and they probably won't be able to come out tomorrow.What could cause a freshly pumped septic system to back up the toilets for the whole house? via /r/DIY https://ift.tt/2Yzarim
