   I have never understood why the tub is 1-1/2" and the shower is 2". Seems like there'd be a lot more draining from the tub all at once.

   Yeah I agree with ya

   I did a job in Medina where I had a 4th yr app doing most of the work cause I was on about 6 different jobs at once.

   He put in a couple of illegal "S" traps after I told him where he went wrong we cut them out & fixed them.

   Then my residential plumber got free'd up from his job so he came to help.

   I got back to the job a few days later & saw the new pvc traps cut out & laying in the garage.

   I asked the app what happened he said ask jerry-------jerry told me that the traps I put in were 2" & code only requiers 1.5"

   After being restrained by the gc from rippin jerrys' head off I calmed down called the shop owner & blew up again screaming for him to get jerry off my job.

   & then calmly told the app why I put 2" traps on tubs cause who wants to stand in water when taking a shower.

   You can put the shower anywhere you want, just use an "Air Admittance Valve" or "Studer Valve". Their easy to put in and as long as you have a main vent stack are allowed in most (if not all) regions.

   Here in WA state there illegal in more areas than not.

   Studor sued bellevue Wa which is our toughest code enforcers----- Bellevue said plumbers could use them but you have to test them with the system.

   Studor says right on the package you can't test them.

   The Mayor trumped the building dept & now there legal ( had something to do with a campagn contribution)

   The inspectors make you sign a waiver of holding the city liable for any failures in the plumbing if you install a studor or aav.

   & the same rule applies if using a studor it needs to be within 5' for a 2" trap arm to keep the trap from syphoning.
