I'm new to forum posting so sorry in advance if this is jumbled. We have a bathroom on each side of the house, and the one furthest away from our Septic Tank is having drainage issues. The toilet has been "slow" flushing for a little while now, but the past week or two, at least a couple times a day, the water will not go down at all. When this happens the shower will not drain either, and if you plunge the toilet it backs up into the shower and the water starts to drain. I'm not sure it makes a difference but we also have very hard water. I'm trying to avoid a plumber if we can because in our small town they charge A LOT.
