Use 45s not 90s just as with any drain line What is the maximum pipe slope for sewer line from main building to septic tank?Please. The sewer line piping should slope between 1/8 inch and 1/4 inch per foot. What is causing this problem and can it be corrected? The Health Dept and the contractor seem clueless as to the cause of this hydraulic overload. In less than 12 months after installation, effluent is surfacing to my yard at the step-down to the 5th trench.

The installation permit and inspection report call this a 'Serial' drain field with '2' trenches. My contractor replaced the failed drain field with 4 trenches (supposedly) level with a step-down to a 5th trench. Since digging with a backhoe and placement of pipes is often not lab-grade precise, careful monitoring and adjustment during construction could be what was needed - and maybe lacking.Īt this point I think the engineer would dig a few test cuts into the system to see how effluent is flowing, and she might be able to fix the system by adding some flow restrictors upstream from the lowest and flooding trench.Īnother alternative might be to go to a dosing system design. I think that a savvy septic design engineer would look very carefully at the slope of the upper lines, making sure they don't slope too much, maybe staying within 1/8' per foot. Otherwise, as is patently obvious, all of the effluent wants to rush down to the lowest point in the system, reaching it quickly and overloading it by saturating the soil just as you have described. OPINION: Design of effluent disposal systems on a slope is difficult: the installation has to control the flow of effluent in the upper trenches, slowing its passage there. What kind of valve goes from the pump to the drain fieldĪs I can't see anything about your drainfield from here in Central Mexico I'm left having to guess.

are involved, but I SPECULATE that you're asking about a check valve that would be used to prevent up-sloping pipes from draining backwards into the septic pump or effluent pump system. I don't know as I don't know what sort of septic system we're discussing, nor where the pump and drainfield are, nor what slopes, distances, etc. On by (mod) - What kind of valve goes from the pump to the drain field
