Here is how to use 45's to make 90 degree turns and to also run however to get to where ever, using 4" PVC. Plan your route carefully. Sometimes it can only go in one place. Make it happen. Do a dry fit first and when you are happy with the way it looks, make a mark on each piece and perhaps even letter them if using multiple pieces., Use the Elephant brand glue...not the watery crap. Use large surgical swabs for applicators. Wipe the ends of pipe and insides of fittings clean. Champher (take off the hard edge of the cut pipe to keep it from scraping all the glue out of the fitting when you stick it together) all cut pipe ends. HOLD them together for at least 15 seconds when you glue them up...they will try to work their way apart...something about capillary action. Cover it up later. Keep is accessible. Put in p-traps on drains and leave an access for cleaning later. Always use a wye to make a clean out for when it clogs later....TIT and they don't think far enough down the line to do this. You will want a screw plug to secure it and other fittings to make that happen. Use a wye as opposed to a sanitary tee, with an additional 45 to make that complete 90. Unused carbons like nice, gentle, swooping routes to travel as they wind their way to the anerobic microbes of your septic tank.

Note: When fabing up an elephants leg (multiple pieces such as that first transition piece) when you do glue the sections together, mark a "G" for glued on each piece. That way if you have been diagnosed with CRS (I refer to it as "Part-timers") like I have....you won't be haunted later on with that one frikken piece you forgot to glue and now the house is finished and it is hidden inside the wall, floor or other place that you can not get to without a major, major renovation.

Me (I supervised) and my invisible, make-believe Thai helper (he did all the work...no work permit needed for him, heh-heh) conceived, contrived, concocted, cogitated, co-conspired, cussed, constructed, copulated with, cussed some more, and completed this little project and to date....works like a champ! If you run two toilets into the same line going into a single septic tank, you should vent them both so as to not have one suck the other one dry when they flush...it breaks the suction route. Do all this and you will be happier than sh*t...pun intended. And when your supervising it yourself...there is no payday on Friday or any other day, shit still runs down hill and do not, under any circumstances....bite those finger nails. Happy plumbing....ett

can't wait for part2 when you describe how to use four 45s to make a 180º

joke aside! i admired my poolbuilder who made perfect bows of any degree by heating up 3" pipes. when i raised doubts that he could do that with 4" pipes it took him less than 10 minutes to prove me wrong.

Hi Naam,

What schedule pipe was he using and did he use something similar to this? What was the smallest radius he could do?

Hi Naam,

no idea about pipe grade (it was pressure, not sewage pipe). he used a blow torch as shown by you but wrapped strong aluminium foil -called aluminum in North America - to spread the heat more evenly.

due to special circumstances the 3" pipes needed bends of ~110º and because i was fascinated he did also did a near perfect circle with a 2" pipe using the well known trick filling the pipe with poolfilter quartz sand.

One handy trick is that toilets generally come in the type that have the outlet through the floor. There are available a couple of types that have the outlet at the back so it can go straight through the wall which sometimes makes things easier.

Thanks, Naam. I'm gonna try to do that myself, with thin wall 3". Hadn't thought of the aluminium (please note spelling ), but filling the tube is an old tube bending method.
