How can I get my toilet to flush?
I recently purchased a small cabin. It is quite old but, has new plumbing. For the first a day or two the toilet flushes with no problems. After a couple of days the toilet bowl will fill up to the rim but, not overflow. Sometimes it will empty slowly and othertimes it will stay for days. We have tried plunging it and using Draino. The septic tank is supposed to be new and we only use the cabin for about a week a year. Is there something I can do to fix this or do I need to hire a professional??
