venting

Bought a house built (poorly) in the 90's. In the master bath, which is on a concrete slab foundation, the toilet has given me issues since moving in. It's an old Proflow 1.2 gal/flush model that was probably the cheap contractor special at the time. Symptoms: - 50% of the time, after...

I'm praying someone qualifed can help me out with this venting question (TERRY!!!!). I'm adding a shower to a half bathroom in my one story house and need to know what size vent pipe I need to support the fixtures. Right now I have installed a 3" vent pipe that goes through the roof and is...

I'm remodeling a bathroom in NYC (NYC Plumbing Code, 2014 - ie IPC 2009 with amendments). The current layout has a horizontal section as the main vent line for the soil stack - see existing diagram for reference. We are adding a washer/dryer, and shifting all plumbing to the about 2' or so to...

Hello, Is it OK code wise, and functioning wise, to vent a drainpipe off of another drainpipe that is well vented? I have a 3″ toilet pipe vented with a 3-inch through the roof pipe and another 3-inch toilet drainpipe, nearby as they both get closer to the main stack (within about 8 inches)...

Hi, I discovered that a toilet in a home I rcntly purchased, when flushed, will draw the water out of the shower trap. What would cause this and is the fix worse than the problem? Thanks for any ideas. (On 4 inch concrete slab, in South Florida)

I have a toilet that recently declined in its flushing power so I decided to purchase a Flushmaster universal replacement kit and replace the guts to our toilet. The problem however is that this particular toilet is an old American Standard 4049 Vent Away so there is the extra vent hole at the...

Hey Guys, I'm finishing my basement, and adding a bath in the process. I'm hoping to get some help with drain/vent questions. The current stack is right in the middle of where the new shower will be. I'm moving it against a wall just a few feet away. I'm just a little confused on how I should...

I’m installing a new 2nd floor bathroom with a freestanding tub. (There is a separate shower and toilet with its own drain.). The drain we can use is the 1 1/2” vent pipe coming from the 1st floor tub/shower combo. This exits to the roof on one end, a septic on the other. 12” wood floor but I...

I would like the p trap to be in the wall instead of outside. I dont have enough space to place a dryer next to the washer with the exterior p trap. I currently have 1 1/2" pipe for the drain and p trap and I was told 2" is required? I'm in california. My issue is that there is not enough...

Hey all, New homeowner here, been remodeling the whole house. Bought a Rheem 50 gal platinum plus gas (natural venting, only powered flue flap no fan) on clearance. Looked in the manual and it calls for B vent. Ran it out the house and up the side above the roof (per local code). Issue I have...

Hello all. I have used this site as a great resource and found enough info to where I think I know the answer, but want to make a unique thread to be sure. Thanks in advance for the help! I am moving my washer and dryer for a basement remodel with the goal putting them side by side and...

From the manual on page 44: "In high temperature applications, the exhaust temperature can exceed 149°F (65°C). In that case, you must use Schedule 40 or 80 CPVC or Approved Polypropylene in the USA or Type BH Special Gas Vent Class IIB (CPVC) or Class IC (Polypropylene) that conforms to...

I recently bought a house built with all of the plumbing in the slab and did a whole remodel. It was a bank owned property built in the 50s, and needless to say I ran into quite a few head scratchers. As far as plumbing, I replaced all fixtures and traps. In doing so, I noticed that the only...

• Occasional odor coming from MBR sink. Not repeatable on demand. • All sinks, toilets, shower, tubs drain easily. No gurgling or bubbling. • Using a bright flashlight on the sink trap and looking down the sink trap I see the following: • trap always has water. • trap water line has slight...

*Storytime* :D For my family; I manage a 38-acre, private, saltwater lake property on the Intercoast of Texas with fishing & camping for a membership fee. Except, people don't want to come camping because we don't have a proper 'Bath House' just an accessible 1/2-bath restroom. I looked into...

Hi all, I'm installing a full bath where a kitchen used to be and am trying to use some existing plumbing. There is a vent connection that will be downstream and below the p trap of my new sink. I am wondering if this vent connection will still siphon my new sink p trap if I add a new vent...

I have been reading about plumbing codes and methods on this site for many years and I learned a lot but I still don't know everything so I must ask a question. I have removed all the cast iron DWV parts so everything will be PVC. I am also installing a full bathroom and seperate floor drain...

I'm replumbing an existing basement bathroom that doesn't have vents. Does this diagram look right? 1. Can I add a shower vent to the end of the 3" main horizontal waste line just beyond where the 2" shower line meets it? Is this to code? 2. If the sink is vented, do I even need to add a...

Hi there, I have noticed some post that have provided me with good information but I thought I would make my own post to more specifically address my questions. I have an outdated electric tank water heater and I am considering switching to a super high efficiency (condensing) natural gas...

Holy Cow today has been a total head scratcher! Props to everything that you professional (and amateur) plumbers have to go thru. I have racked my brain all day today trying to figure out this wet vent and I have to admit defeat. Any advice y’all can give to this newbie will be greatly...
