thanks for your informative reply. i will check for clogs i find changing the P trap a little daunting because of the space. if i just changed the section of pipe do you think would it make a difference or am i just wasting my time?

My ceiling is open and I have the opportunity to improve some plumbing. My bath empties into a 1 1/2" P-trap and connects into a 2" branch. (see diagram) Would there be an advantage to re-plump the highlit section of 11/2" drain pipe to 2" after the 1 1/2" P-trap to the 2" Tee? Would the drain...

I think I just found the answer to my question 1). 5) At least one soil-or-waste stack or vertical soil-or-waste pipe must extend into a stack vent or into a vent pipe that is terminated in open air. That soil-or-waste stack or vertical soil-or-waste pipe must be as far as possible from the...

Just referenced the National Plumbing Code (Canada). Multi-story wet venting is allowed provided (in the case of 2"): h) where a wet vent extends through more than one storey, the total discharge from any one storey above the first storey does not exceed 4 fixture units, so I should be good...

ok i think i get it. it is virtually impossible that water draining down a 2" pipe from a draining kitchen sink would siphon a lower trap. but anyhow the code is the code. i guess the proper solution is to run a 1 1/2 ABS parallel as a vent stack which would be so much work. i would have to...

thanks for your comments. the drawing is not detailed enough. have updated see below never though of that. stack 3: the bathrooms are connected through a vent stack and the number of units are OK for 2". i have 27 fixture units and according to code i am allowed up to 60 units for the length...

in my jurisdiction roof drains are connected to DWV as there is no separate storm sewage system from housing. according to formula 2 x 2" vents would work but are there any other specific requirements. if you have time would you be able to address my 3 questions? thanks

see diagram below My building is a 3 story building. The main drain is a 4" in the basement. I have one 2 soil stack and one 3" soil stack that is reduced to 2" above last branch at the third floor. Both stacks are then enlarged to 3" in the attic and exit the roof as 3". I also have a 3"...

Hi, Could get some epoxy paste and rebuild/fill the area. https://www.pcepoxy.com/products/permanent-repair/pc-11-paste-epoxy/ I feel your pain. I installed a MAAX acrylic tub 4 years ago. It started leaking last week. Took the drain apart and noticed that the area under the tub around the...

Thanks to Terry and everyone else for your input.

Hi, First time posting. I am renovating an older building and want to correct some plumbing in the process. 1. The 3" stack vent was reduced to 2" above the last fixture at "B" then upsized back to 3" at "C" before it exits the roof. I assume I need to replace that section of 2" with 3" to...
