This single line would then connect to an existing main line located halfway down a steep (34°) slope. The proposed alignment for the consolidated sewer line was 319-feet long with more than 30 feet of vertical rise through glacial soils which terminated in a gravel mantle.Matt StephlL.E.GMichelle L.

Another possibility is that the remaining vent piping itself is leaking somewhere such as under a floor or in a wall. The most-reliable test is a pressure test of the vent piping system, but a sewer line inspection camera might also show up a problem without having to tear open walls or...
(L2) is the cross-sectional area of flow, x (L) is the distance along the conduit, t (T) is the time, H (L) is the hydraulic head of water in the conduit, Sf (L L−1) is the friction slope, hL (L) is the local energy loss per unit length and g (L T−2) is the...
