4,000+ ft BUT it has to be vented properly with the correct pitch and treated as a soil horiziontal line and then the vent calculated on the developed lenght or pipng and fittings and allow for cleanouts at every change of direction greater then 45 Deg and install a clean out every 50 ft at a right angle to the soil line flow. BUT check your local code as some have no clue to proper venting
Maximum distance of the toilet to the drain is 6 metres (20 feet). The angle of drop is set by the branch at 112 1/2o, which equates to about 1/4" of drop per foot.
50m
toilet should have a vent with in three feet of down pipe, but as long as you are with in the drop range for hori. pipe run you can go as far as you want, but you need that air vent close as you can so that the suction from the toilet water does not pull the rest of water from toilet base(p trap).
The main toilet pipe is partly plugged after where the upper pipe joins the lower one.
Yes if the vent pipe is 4" and vertical by code and there is nothing connected between your toilet tee and where you would connect your new toilet tee. If not worried about codes then yes you can connect to a 3" vent line if no other vent lines are connected down stream. If you have a vent pipe that is less then 3" and or you have other vents connected between your old toilet tee and your new toilet tee then NO you can not connect a new tee for your toilet.
It's not the toilet, there's a blockage in the pipes some where after the drain pipe from the toilet joins up with the drain pipe from the tub.You're going to need to have the pipe snaked.
Usually toilet flange is glued down onto plastic drain pipe. There is a toilet flange that can be glued inside of plastic drain pipe also.
Who needs a toilet
The laundry waste pipe is fitted to the main drain near the toilet and the main pipe down the line past toilet is partly plugged, forcing the laundry waste up the toilet waste tube. You need to auger the pipe from toilet to outside. If all the piping is in ground you will have to remove toilet from floor to do this properly.
Toilet flanges OUTSIDE of the pipe including cast iron and brass to lead
Yes.
The easiest solution would be to move the toilet so that it lines up with the waste pipe.
