Does this make sense to you?
Our basement toilet won't flush during times of heavy rain. This happens about 1 or 2 days a year, usually in winter. We've learned to live with it. I have two fields - a new one installed about 4 years ago and a diverter valve - this issue happens no matter which field I'm on. As soon as it dries out, the system works fine the other 363 days a year. And this cycle has happened for the last 3 years. 3 years of 363 straight days of a normally working system tells me that my fields are fine - perhaps the situation is not ideal - yet it's just the nature of what I have.
So the ground becomes extremely saturated, the fields cannot purge off water, and the tank fills with water, as does the main line coming into my basement slab.
There is a syphoning effect happening with the basement toilet. The water in it is actually "connected" to the water in the drain, since that drain is full up to the toilet. Since those waters are touching, as the drain tries to purge, it pulls the toilet water down with it, interupting it's flush cycle. When the drain line finally dries, there's an air break and thus the toilet works normally.
Yet we continue to use water upstairs, and it does not overflow the basement toilet. I believe this is because the weight/pressure of the water upstairs (with more gravity behind it) is actually pushing/forcing the water toward the lowest drain - which is actually the septic fields, not the basement toilet or shower. I specuate that if we had no basement toilet/shower, we'd never even know we were having an issue.
So - based on everything above, is it reasonable to think that even when the fields are super-saturated, since they are lower than the whole house and every bathroom, natural water pressure from the weight of water in the house drain pipes could actually force water through the tank and squeeze it out the drain fields?
