- POST a QUESTION or COMMENT about septic system D-box installation, inspection, troubleshooting, and repair or replacement
Septic system drop box piping: what type & size of pipe is used from septic tank to D-box and from D-box into the septic drainfield or soak-bed trenches?
Septic system D box installation, specifications, inspection, diagnosis, and repair: in this article series about septic system drop boxes we describe the best procedures for locating and inspecting, repairing or replacing the septic drainfield distribution box, or the "D-box" or "Splitter box".
If the D-box is leaking, smells, or is tipped, clogged, or otherwise not working this article describes how to diagnose & fix the trouble.

Septic D-Box Piping
Question: are the pipes from the D-box solid or perforated?
are the pipes leading from the D-Box have a drywell system) solid or perforated, , one side of the yard is very wet, the other side seems bone dry, could one the pipes either clogged or the other broken, not sure which one to dig up 1st - Joe M
Reply: It depends on septic drainfield layout
Our photo (left) shows a septic system drop box or D-box being installed in a new septic soakaway bed in Tucson, Arizona in the U.S.
Joe the use of solid vs. perforated pipes downstream from the D-box would depend on the septic field layout, but typically from the D-box there will be a solid effluent-carrying pipe serving as a manifold that then feeds individual perforated lines in drainfield trenches.
In theory in my OPINION there is nothing preventing the beginning of gravel-trenches quite close to the d-box, in which case wherever the pipe is running in a gravel trench intended to absorb effluent, the pipe would be perforated.
But I would NOT run perforated effluent piping through mere soil backfill (i.e. not a gravel-filled trench) as you'd be inviting soil infiltration and clogging of the line.

Woodson also discusses ways to increase profits by avoiding cost overruns.
- [7] Country Plumbing: Living with a Septic System, Hartigan, Gerry: $ 9.95; ALAN C HOOD & TP; Quoting an Amazon reviewer's comment, with which we agree--DF:This book is informative as far as it goes and might be most useful for someone with an older system. But it was written in the early 1980s. A lot has changed since then. In particular, the book doesn't cover any of the newer systems that are used more and more nowadays in some parts of the country -- sand mounds, aeration systems, lagoons, etc.
