Slow flush septic during heavy rain
I have a home with an in ground septic system, it normally works great; however during periods of heavy rain the toilet nearest the discharge either flushes very slowly or not at all. The upstairs toilet as well as the guest bathroom across the house (farthest from the septic system) work fine even when it rains hard. My question is: can I fix this slow flushing toilet by installing a grinder pump inline outside in a pit between the home discharge pipe and the inlet pipe to the system tank?
