I am currently adding a bathroom to the basement. It's a small bathroom 4 x 6 feet. Are my vents correct ? Keep in mind my vent for the toilet and shower connections are going to be sanitary-Tee's or Wye's laying on its back.
I have two options for the shower vent. Do I run it to the back wall and up or should I run it to the left over the soil pipe and up?
The sink will be a wet vent. When connecting to the 4 inch soil pipe, will I need a sanitary tee or wye to on its back or can i put it on its side?
Do I need a vent for the toilet ?
Is it better safe than sorry and vent everything ?
Any help is greatly appreciated.
