Yesturday I had our septic tank pumped out. We have only been here 2 years but we knoew it had been a while since it was dune. Boy were we right the gentlemen said it was very very thick. Okay he cleaned it out. Now today my toilet is not working right when you plunge it nothing comes up after a few time it goes down very fast . So my husband went out saide and dug up the septic lid when he opened it it was full of rain water. Is this normal or do we need to redrain things.
