That would depend on PITCH more pitch more fixtures allowed
In Tulsa Oklahoma you can, but i would still use 4 in.
A 3 or 4 inch pipe sticking straight up out of the ground? This is the clean out for the sewer line. If sewage is coming out of it, this means the sewer line is clogged or collapsed from there to the main city sewer. If you have a septic tank, the tank is full and needs to be pumped out.
1-foot section of pipe contained 0.6528 gallons of water. 1/4 inch per foot but standard would be 1/8" per foot sewer line necessary in a house. alliedallcityinc.com
1/8th per inch
3" house (building) drain allowable. 4" building sewer line needed for house from sewer main.
The length of a 4-inch line is 4-inches.
Yes. A reduction fitting can be used.
1/8" per foot.
A sewer "rod" is normally no larger then 3/8 of an inch diameter BUT a SEWER Cable can be as large as 11\4" even the small sewer rods can have large heads to maintain sewers as large as 36"
Depends on locality as many of the one family homes require I install sewer mains from 4" - 6". The size of the "sewer" is based on fixtures units that are connected and to local codes
First there should be no reason the a home needs a 4 inch waste line. Three inch is more then enough. But if you insist use a "consentric' reducer as opposed to the " "ecentric". Other wise your waste will have to jump up from the four inch , and you will have back up.
A basin, bath, kitchen sink, shower and bidet all have 2 inch (50mm) outlets, a toilet has a 4 inch (110mm) outlet which all connect to a gully (4inch) or stack (4 inch) outside which connects to a main sewer line. A main sewer line can either be 4 inch or 6 inch (160mm) depending on its application and the length of the sewer line.Depends on the local / state /national / country codesSome codes require a basin waste to be 11/4 and the trap to be either 11/4 or 11/2 Kitchen sink some codes require 11/2 waste and 11/2 trap the better codes require an 11/2 waste and a 2x 11/2 trapA toilet waste can be as small as 3" or up to 4"The length of the sewer has no bearing how many fixtures are connected it goes by fixture units and PITCH the venting does go by developed lenght and fixture units connected ( 7.48 gallons Or 1 CUBIC FOOT = 1 FU)
