I think this runs to a slab.... I'm hoping round 4 of draino fixes it.
“Hi Everyone Hoping you all might be able to point me in the right direction. I am a renovator, client had the plumbing rough in done by a plumber before I was called. They went with a floating vanity, and the stub out is too low for me to plumb it in a straight line. The P trap is at the height I need for it to clear the bottom drawer in the photos. Any way other than cutting up the drawer? submitted by /u/CraiggyJSmoothBrain [link] [comments]”
“Do you really have the elevation to have that combo rolled to a 22½° on the end for the water closet? Is this going underground or in joist space? Because you can use a short pattern 90° under a water closet. Hell you can use a closet bend. I would just use a 22½° on the end of the horizontal to aim towards the W.C. center to a regular pattern 90°. It'll save you a lot of height. Wouldn't even bother with the cleanout on the end. No one is opening a cleanout if the toilet is backing up b”
“Hey everyone, looking for some professional opinions on a low-slope to steep-slope transition detail that is currently causing an active leak in my home. The contractor (a certified GAF installer in Southern California) ran a PVC single-ply membrane for the low-slope section. At the transition to the steep-slope concrete tile roof, they tucked the tiles under an unsealed PVC flap and reinstalled the cap tiles over it without any mechanical attachment or transition flashing. The issues I’ve ident”
“This is a tar and gravel flat roof with a drain. If you all think it’s possible, can you point me to any resources for what the assembly material should be? Is water supposed to drain to the center of the roof or fall off the overhang? I am in Quebec so there is snow weight to consider during the winter. submitted by /u/steve_333 [link] [comments]”

“Just had my gutter system replaced and I noticed water rolling down the exterior of the downspouts after the first light rain. The downspout outlets appear to be installed dry except one with a volcano of sealant at the corner. Should I ask them to remove the screws penetrating some of the downspout outlets before sealing it up? Any other critical things I should check before they come back? Also noticed many of the exposed metal edges at ground level are razor sharp. submitted by /u”
“My AC condensate pipe in my upstairs closet above my stairs had a small crack that leaked. Eventually (don't know how long it was leaking) the water made its way to the ceiling below which is when I discovered the issue. The leak is repaired. Question now is, will the ceiling dry out? My brother thinks it will. The ceiling is not soft to the touch or sagging, but pinless moisture meter is reading 60% in almost that whole square. submitted by /u/Extra-Coffee-1524 [link] [com”
“Background: Ok so we just bought a house that is mostlu asphalt roof but has an addition with a rubber roof. That rubber roof has almost no pitch and when we bought it, it had quite a pool of water on it. We got a ladder and went up and swept it off and its dry now. There are no visible leaks inside or any problems. Dilemma: We have had 5 roofers come by to give us quotes. All reputable and well reviewed. 3 of the roofers have said the rubber is good. The flashing is good. Pooling water is fine”
“Noticed water droplets on the basement’s drop ceiling framing. Pulled back the drop ceiling tiling and water poured out of it. A few of them were affected. Looked into the space above and I couldn’t find any live water. However I noticed the joist/subfloor? was damp where the vertical copper piping goes through (PICTURE 1). There is a shower fixture above the area - within a foot or so. I turned on the cold water and didn’t notice anything really. But once turned to hot, I could see the water dr”
“Hi. Not sure if this is the right place to ask. But the window well of a newly purchased home (northeast Ohio) was full of dirt. When I did some excavating, this is what I found. Anyone have any ideas what kind of drainage system this is? Or what’s going on? Note that in the back left it looks like there may be a broken clay pipe. But hard for me to determine because it’s gotten too deep for me to reach. Any ideas what to do next? Fill with 3/4 stone? Also — the bit of moisture is from me sprayi”
“Hi i rsally have no idea how to explain this so please forgive me and as you can tell in the images attached my wall is missing it's bathroom pipe. I had taken it off because the pipe was leaking (my dad built this bathroom and the pipe and stuff) and I thought taking it out and replacing it would be easy...its not. First of all the hole connected to the wall (which is where the dirty water exits into the drain) is very small, the first pipe i bought was too big and the second was the exact”
“I found this in my ceiling when drops of water started falling from it. This is the drain for a 2nd story shower/bath combo. Is there a way to raise this up like 1/2”? It’s currently about level with the bottom of the drywall. Whoever worked on this before just caulked it a put mud over it. submitted by /u/resuar3v [link] [comments]”
“We have an extension to our living room which has a flat roof. It was re-done about 12 years ago when the previous surface was cracked and caused a leak under it. There are no signs of wear to the surface now so we are wondering if the rain got in a seam/crack and ran to the light fitting ? We never noticed last night when the storm was at its worst, only today spotting a damp patch on the carpet under the light. Obviously switched the light off now but wondering how long it will take to dry out”
“I have a leak on the ceiling. Coming from the square area that is circled. It's a commercial unit, and the the AC units are on the roof, while our space is on the ground floor. There is no second floor, just this space in between for HVAC and wiring etc. Before I call in the HVAC people, is there an idea on what it could be so I dont seem like a complete idiot in front of them?

“Skylights on cathedral ceiling are leaking. Found out when water started dripping from a downslope potlight and wall window. Insurance sent a roofer. He shared that the skylights had been replaced at some point (I purchased 5 years ago) with used skylights and that made them less likely to be well sealed. Basically they need to be replaced. Also the beams are soft (rotting he assumes) so that will need to be repaired. Would it be better to replace the 2 separate skylights with 1 large skylight,”

“Could this poorly formed ridge capping be the cause of water getting into our roof cavity? The house was built in 98 and you can see someone has been up there trying to fill some areas with caulk, which has since deteriorated. I've only seen water actively coming in once during a passing cyclone when it was basically raining sideways but there is staining on other internal ceilings likely from older leaks. Can I just beat the capping so it sits in the corrugations better? submitted by”

“This past Friday, I had had a small leak in my HVAC vent duct, (no ac was running) during a flash rain storm. I assumed it was a leak on my roof. I was getting ready to call someone on Monday to seal leak areas. Today (Sunday), there was another hard rain storm (around 3 hrs). Not a drop/ no evidence of a leak. How is that possible?? The house is a raised ranch. The location of the leak is not right at the edge of the front of the house(maybe around 9 feet from from front edge) submitted b”
“We have leaks underneath where the main house roof (left) transitions/connects to the black torchdown carport roof (right). I plan to remove layers to get to the rotting wood and replace. But is this a good setup to replicate when putting back shingles and everything? Both roofs are about the same height which I assume is why there is that big transition area to start the angle higher up. Just trying to go about putting things back in an ok/better way or how best to join the 2 roofs. Thanks in a”

“My pan leaked and ruined my ceiling. The sensors weren’t wired properly and the drain was super loose and not siliconed. The system was installed about 10 yrs ago.

“This is my kitchen ceiling, which is directly below my upstairs shower and boiler room. The first bubble appeared 3 days ago and the dripping has progressively got worse despite me not using the shower at all in this time (have just flushed the toilet and ran the sink tap briefly) and the water meter remaining the same besides the brief usages. My plumber couldn’t work out what’s causing the leak, and is now not responding, and a trace & access plumber can’t get here for another 4 days. What”
“First house PLEASE ADVISE I desperately need some advice on how I can fix this this weekend properly. Just slapping roofing cement and tape on it feels like the wrong fix. Backstory: there was heavy wind and rain going directly against the direction of the shingles and water made its way under the flashing and started leaking in my door frame of the 3 season room below.

“I came home on a rainy day to an active leak. The next morning I cut out the water damaged section of the ceiling to uncover the problem. It appears to me the water is coming from the flashing but when looking at how it was installed I don’t understand how it failed. Everything overlaps correctly and runs downhill away from the house. There was a small split in the caulking outside but like I said before everything overlaps correctly so that should be the issue? I can see that the portion of the”
“If it stops when you turn off your water you have the answer. Call a plumber for a leak detection and pin point location of the leak, either with a thermal camera and or a listening device! That's how we find leaks without just tearing shit apart.”
“Previous post used an old photo before I redid my sidewalks and changed the direction of the gutter to tie it in with drainage lines taking water to the back yard. Current issue is water comes off here and eventually makes it into the basement. I know the sure shot is to add some gutter and a downspout, but I’d rather not bust up the new sidewalks to tie into drainage for about 2’ of gutter. The gravel along the side is a French drain that catches water off the sidewalk and what falls between th”
“So during a recent reno our contractor foolishly painted over all of our large rear low-slope roof's (aluminum) soffit vents. After considering a couple of options we've decided to replace all the soffits (with vented aluminum) and to take this opportunity to increase the ventilation somewhat. The work went out for bids and I got a bit of a shock when 3 out of 4 bidders suggested they would likely have to replace the downspouts and eavestroughs as well. All of that rainwear dates from 20”

“Preface this by saying that the previous owner butchered the fly rafter which has caused the decking to droop. It’s on the repair docket for 2027. Rain comes off the overhang at the bottom and eventually makes its way through my century-old foundation. Could a diverter be the solution here? I really don’t want to put a 2’ piece of gutter there with downspout since I’d have to cut recently installed sidewalks to tie into the drainage. submitted by /u/wrongsideofthewire [link] [c”
“Most of this is near the chimney flashing although I'm not 100% that that is where the leak comes from. Just today during the rain I discovered a wet patch on the interior of the roof surrounding a nail hole. Nothing else was wet. A lot of the plywood wood with damage here is flexible to the touch and I'm assuming it needs to be replaced. I supposed im looking at replacing a full 4-8' in width up to the roof peak. Does this seem accurate? What's a ballpark for a job like this? &#”
“Hello, we noticed that some water is getting over the foundation into a corner of the basements. It only comes when the rain hits side of the house at a specific angle. The front of the house in that corner is brick and the side is siding. Since the water appears to come in from the frame, would we need to call a siding repair company or what?

“Hi everyone! I just bought a home that has a flat roof with drainage problems. I believe it’s due to the pitch not being correct and getting water to the gutters, so it settles and then leaks in to the house. Any ideas on how to fix?

“Hi folks, Background: I found peeling paint in my office ceiling which led me to find a leak in my new (9-10 month old) metal roof. Went to the attic and found the culprit to be a sewer vent pipe (chimney pipe thing in the photos) that had water running down the outside of it from where it went through the roof. Suggested fix: When we called, the guy did not seem surprised at all and was super nonchalant (not very comforting), and suggested a quick exterior patch and painting over the ceiling da”

“My home’s roof has a couple of spots where it is sloped incorrectly - in the 1st photo it slopes slightly back towards that corner, in the 2nd it slopes up slightly right under the drain.

“Just purchased a new (to us) home and realized today that some pipes leading from the unit are leaking into our ceiling. It seems the leak is coming from the pipe with the red cap next to it and is traveling down that pipe to an elbow 5-6 feet away—I have placed a bowl under it. We have a call in to the home warranty company, but we have to go with whatever technician they send out so I would like to have a basic understanding of what’s going on. Google tells me that the red plug is indicative t”
“Hi everyone, I’m looking for some professional advice on a detail involving a steel balustrade and drainage at a balcony with a projecting slab. The main issue is that I would like to avoid using a conventional floor drain, mainly because the balcony has a relatively shallow depth. I’ve attached a schematic section showing the proposed assembly. The balustrade needs to penetrate the final floor finish (stone or porcelain tiles), which is designed to project beyond the edge of the concrete slab a”
“We realized that the builders of our home really messed up the basement toilet. We had a plumber over who charged a ton just to pick up the toilet and asses the problem. Our flange is an inch too low, offset, and the pipe is at a right angle. He said the floor would need to be torn up to fix it. Is that true? Is there any way to fix this ourselves? We really can't afford to do the repairs he mentioned, but he left with the toilet sitting in the middle of the bathroom. submitted by  ”

I’m fairly handy and if I know the part I need, I can do it on my own with the help of a buddy. I guess the previous homeowner had tried to do a repair and my inspector didn’t say anything but my warranty said the tech they sent saw evidence that the unit had been attempted to be repaired and that the”
“This house is from 1905, drainage system was added 2019. I cleared out the drains outside, and last night the heavy rain pushed a lot of debris out of the drain that services this side of the house. Should I wait to see if that fixes the problem or pay for hydro jetting? Should I repoint this interior wall where the water was seeping in? Photos are of water in the house, the hole where water came in, the downspout that feeds into the drain and the direction where it drains underground. Thanks &#”

“I've got a dreaded roof leak - The company has come out twice to fix it, both times doing a touch up or stating it's fixed. The last rainstorm we had, it continued to leak in the same location(s) - One of these is under a plumbing exhaust vent in the house. The only way to confirm this is to cut open the area which we have not yet, but I was advised to put PVC U-Pipes on the exhausts as a method to keep rain water from entering and leaking in further. Does this cause any harm to the exha”

I find it ridiculous that we already have a leak, but then again this is the first time this has happened to me. I feel like this is a weak point in the house as we replaced the roof mostly because we had the same thing happen to us before and at that time that roof was over 20 years old.
