vent

Folks need some advice. I have a100 year old house with slates that often leak so time for a new shingles roof. I also have two bathrooms in the 2nd floor right below the attic. Looking from the attic, the distance between the light fixtures in each bathroom are about 18 feet apart. I want to...

I am having a problem with my new sink setup. I had a double bowl and went to a single bowl sink. Now when I put water in the sink the water drains slowly UNLESS i take my finger and push the disposal guard down to increase the opening more, then once I do that there are a bunch of air bubbles...

I live in central NC. I am building a yurt on my farm (w/ 3" septic) and I am having trouble figuring out the waste venting for my fixtures. Our yurt is a round, soft-walled structure where the exterior, weather-facing layer is a type of extremely durable vinyl composite fabric. I cannot cut...

Instead of the typical loop vent for an island which would require concrete work, I'm opting for a column on the island to run the vent up to the attic to tie-in to a near by vent. Considered the AAV, but decided to avoid that path if possible. Would either of these vent configurations work and...

Hello all, new member here. I live in Southern California. We are going to have a bathroom moved from one interior part of the house to another part which will be against an outside wall. It was suggested that sink, shower, and toilet drains can be vented out the wall instead of through the...

I installed a wye with a street 90 going out of the 45.. going to the lav. I think its looks funny. but plumber running Job says its ok. any advice.

Hello, I am renovating my bathroom in my home built in 1936 (1960's remodel?) It currently has 4 inch cast iron pipe for waste line that is starting to leak and corrode at the joints. I am wanting to replace the old pipe with pvc and want to make sure that the basic routing of it is up to code...

Is it OK to start a vent off the 45 side of a wye? I don't see why it wouldn't but couldn't find an example of my situation on the internet, See attached drawing (sorry it's rotated wrong), Originally I was going to put a sani-tee after the trap arm start and start the vent with a 45 from the...

My plumber says the height of the drain from the kitchen above is correct. Maybe I’m over-thinking the height but I think it should be 12″ from the floor not 32″ as shown in the picture on the left hand side. My concern the bathroom sink drain is below the kitchen drain. Is he right?

Hi, all. I am in Texas and am in process of renovating a master bath. We are putting on a freestanding tub in place of the old so I need to move the drain. I wanted to check with you all to see of I'm planning this right. The picture I've attached shows what I want to do. Imagine you are...

Love the site. I'm a DIYer, and a plumbing newbie. I'm redoing a bathroom and was wondering if I can do something like the following? T The drain would be 3" and the vent in the wall would be 2". Can I do this? Is it okay for the vent not to be directly in between the fixture and the...

Firstly, apologies if this isn't the ideal forum to post this in. Feel free to redirect me to another forum. There is a rental cottage on our property that has an "external shed" attached to it. Does the door (removed in this photo because I need to strip and repaint it) need to have a vent...

I see tons of questions about a 90 being vent only (short sweep), but can't find anything about a 45. Is there a 45 elbow that's for a vent only, and not drain? In the attached screenshot, I'm wondering if the bottom 2 are for vent only? If not, what's the difference between the top 2 and the...

Hello! Currently I have my water softener draining into my floor drain with an air gap and that floor drain connects to the ejector pit. Every time my softener regenerates the pump needs to run almost the entire time during regeneration. I do not like relying on this pump to prevent overflow...

We're starting a remodel of a half bath/laundry room, on grade with a concrete slab. I recently pulled the drywall off and carpet up to see what we're working with, and I quickly found that nothing that currently existed in the space had a vent. The toilet appears to have been added at a later...

Hi, I am gutting and re-doing a 2nd floor TINY bath in a very old house. I have mapped out the Drain/vent system for the 3 fixtures (shower, toilet, sink) all dumping into the common 6" cast iron waste stack. Here is the proposed sketch...

Hey all, I've been lurking for awhile and finally have a question that I think would benefit from the advice on this site. I'm going to be moving my kitchen sink drain from one wall to another. Fortunately, the current drain/vent line is just a few feet away (in the basement) from the sink's...

I think water is coming up from under floor around this pipe which is in middle of the basement in the wall. I knocked out the drywall and pipe comes from floor to about 5 ft high with a vented cap on it. I can't get pic to upload. I think is a vent of some sort. I cannot find a floor drain...

I am needing to re-locate my laundry room. I got a quote for the work that was way more than I can afford currently so I'm going to try and tackle this myself. Some of the decisions I've made (e.g. using a mechanical vent) are b/c I have to get this done quickly and as inexpensively as possible...

This is a request for advice prior to seeking a few local estimates. I would like to have a utility tub installed in the basement directly below the kitchen sink in our mechanical room. The kitchen sink waste line is 1 1/2" pvc fed into a 2" vertical PVC line with cleanout 24" above slab that...
