venting

I have a question about his shower being vented at this 3" vent. A. Is this vent too far, and B. can it have this many turns before it vents?

I have a vent running really steep. It wouldn't make sense to me that there's any code for too much slope in a vent since no solids but just wanted to check.. Thx

I've helped plumb a few houses but am a little rusty.. does this layout look like it would pass inspection? In a basement under slab. 3" from sink to sewage pump to act as a "wet vent". 3" to toilet. 2" to shower with a 2" running over to the sink as it's vent. I would run that up beside the...

Hi All! I live in a 3 story townhouse. The first story being ground level (above ground basement). My issue is that even though I have hot water in the tank available it won’t travel to the 2nd & 3rd floors automatically. I have to go to the ground level & turn on the hot water tap in the...

Hello, I want to add a bend to my vent stack before it goes through the roof. Is this ok to do? The vent serves one shower drain and one toilet drain. See photo. Green is what it does currently. NOTE: I'd like to REMOVE the GREEN LINE entirely, and replace with the yellow line. Will this still...

My first plumbing project and I could use some help. This 10x10 bathroom has 2 sinks, 1 toilet and 2 shower drains. Is the single vent on the main sewer sufficient or do I need an independent vent on any of these fixtures?

Hello and thanks for any help you can provide, I am planning on adding a deep sink in by basement and will need to drain it using a drain pump. Was planning on using the Liberty Pump 1/3 HP Submersible Compact/Low Profile Drain Pump Model #404. I am not sure where the best place is to tie into...

I am trying to install a double sink vanity in our master bath remodel. However, when I exposed the pipes to plan my plumbing I ran into a dilemma. How do I tie double sink plumbing into my current plumbing. The issue I have is trying to properly vent and drain the system. In the second photo...

Hello, I have an existing utility tub and previously drained my washing machine direct into the utility tub. I would like to add in a washing machine standpipe in addition to the utility tub, but I am unsure about how to design. I thought about either of the designs within the attached (A and...

Hello, I had a question about the way my handyman installed our washer drain. He tapped in below the 2” sink drain that is already there, added a p trap and installed it to to the washer drain and connection housing. should I be worried about the drainage of the washer. He told me it’s fine...

I was curious if the laundry drain lines and vents are installed correctly in these photos. Eventually, a sink for a 1/2” bath will be added, but I wanted to see if anything needed to be fixed before going any further.

Hi, I'm new to this forum so thanks in advance for the help! Our upstairs bathroom has dual sinks and one of them had a clogged drain. After several attempts to unclog it personally and through a plumber, I found out that the iron drain pipe in the wall was completely closed and thus needed to...

I recently got ground floor piping extended to have drain, hot and cold in a first floor room. Only the pipes are there, but I'd like to install a sink and a washing machine as from the diagram. Note that the washing machine will be at a higher level, because it will be placed on a riser...

Ok here goes. I have a 3 story home with a bathroom on each floor and all are above each other which I assume that means they are on a shared drain line and vent stack. Im having a devil of a time figuring out what the real issue is thats troubling the toilets. I keep thinking I have a venting...

Ok, so here is my issue... I purchased a house a few months ago that is on a septic system. After we were finished with renovations we moved in and started having issues with the system. The toilets would start to gurgle and the shower would start to fill up while in the shower. We thought...

I was told that even though this ties into the main stack, it is not allowed due to it being on a 45 degree angle + it will create a siphon. Is that correct? Additionally, if it is not allowed, there is another vent stack (2") on the other side of the bathroom that I could tie into - not sure...
