How to install a 3 hole 4" pvc sewer drain??

[BHD]

there are two basic methods of doing this,

one is to lay the pipe at a slight down slope so the effluent can reach to the end over time, usually out of a distribution box.

and the second id the dousing siphon where a small tank fills and when full it automatically dumps filling the line full of effluent, in to a level drain field, flooding it from one end to the other,

(mound systems use a sewage ejector pump (basically a glorified sump pump to do the same thing),
and I have read of a few other systems, that do the same thing, one that works like a toilet tank called a float system, and a tipping bucket system, never have seen the last two times,

the 6 o'clock hole is most likely so the pipe will drain out completely and not sludge up on the bottom in time, (even tho in theory there should not be any sludge in the effluent),

Septic Gravity and Float Dosing Systems using tipping buckets or dipping systems, bell siphons, or float-controlled (floating outlet) effluent dosing systems

in most locations you will need perk test, an approved design, permit, and inspection from the local health department, most locations, can and will make one redo it, if there specifications and if the steps are not done to there over site athority,

For French drain we use Big "O" Black with tons of small slits to let the water in. My pipe says right on it sewer .
Talked with a guy that use to install septic fields He said the writing in the pipe faces up so one row will be at 4 and the other at 8 o'clock. Leaving the one hole at 6 o'clock.
Answer solved.

The people here in Florida who do pretty much nothing but installs are using bundled piping. There is only one run from the tank, d-boxes are rarely used, that is comprised of three layers of pipe. There is a top and bottom run of four pipes with a single center run of five. The bundle is band strapped to hold in place. The assembly is wrapped during the installation with fabric. I have seen coarse rock used but more and more plumbers are going without. The only perforated pipe is the absolute center one with of course the evacuation ports downward.

There should be a 1" drop over the 10' run of pipe. This is to allow the liquid to carry any solids with it. If it is steeper, the liquid would flow around the solid & the pip will plug up.

In the U.S., sewer systems are the only thing which is federally regulated & you have to attend a class or have a certified installer.

No solids should ever make it to a septic bed . In Canada a certified contractor is required to install a septic field.

Rasor, you are right about solids shouldn't leave the septic tank. The 1" drop for 10' run is a standard used on both sides of the septic tank & I was explaining why. Thanks for making the clarifying point.
