“we hired a contracting company for a full bathroom remodel that completed about 3 months ago. they are licensed, have good reviews, passed all inspection, got appropriate permits, etc. about 1-2 months after the install, the new sink started to drain very, very slowly to the tune of standing water in the bowl for long periods of time. I took the stopper out and snaked it to make sure there were no clogs. the company sent someone out to look. I didn’t stay with him the entire time but he didn’t b”

“The inside wall is a bathroom where the ceiling is wet. It’s a bathroom directly above that bathroom as well. Upstairs bathroom floor is not wet. This picture is outside the downstairs bathroom. Plumber coming hopefully tomorrow just wondering what it could be. Baseboards also wet. Wall near the water heater also wet which is on the opposite side of wall of the bathroom where this photo was taken. submitted by /u/Lasting_Greatness [link] [comments]”

“A few years ago, while draining the bathtub in my 2nd floor bathroom (photo 1), a lot of water leaked onto the floor and down to the 1st floor bathroom. I opened up the ceiling (photo 2) and called a plumber. The plumber said the leak was caused by an inadequate or blocked air vent which resulted in the water, which drains into the same pipe used by the adjoining toilet (photo 3), to leak from the base of the toilet. We were planning to remodel that bathroom and asked the plumber to go ahead and”

“Leaking area circled in blue. We bought an old house a couple months ago and this joint started leaking last night when the shower was on. Not opposed to hiring a professional but will feel really dumb if it’s a simple fix. Any suggestions appreciated submitted by /u/coffee_paw [link] [comments]”

“A few years ago, I had an old extension rebuilt. As I’d previously had issues with rainwater getting in between the house and the extension so I asked the builder to extend the downpipe to the guttering on the new extension. This has however caused a few issues as the downpipe moves in high winds, so I’ve had to secure it to a gutter bracket with a cable tie. The guttering is also quite shallow, meaning rainwater often spills over the edge. It turns out the original water ingress issues were cau”

I had a new roof put on. The gutters weren't old so they took them off and reinstalled them as they were put on top of the old roof. Now I have…

“Well investigated a wet spot saw a nail dropping water from the attic went to investigate and it got worse and worse. Not really sure what to do and I am feeling kind of dumb because I listened to a family member about using some Henry’s wet patch when I am doubting it did or will do anything. But put a few coats. I got a garbage bag filled with wet insulation and removed it. Pat dried the area and have a box fan facing it now. I did put a 2 x 10 with a bucket underneath to catch the water where”

“Hopefully this is the right sub. I have a flat roof on my garage. This “garage” is really just an enclosed carport. I have owned this home for a year. Water pools near the end of the roof and doesn’t flow nicely towards the drain. When I bought this house, there was lots of water damage near the drain. It was rotted out so dad that you could see outside from the inside. I had a contractor come repair it and he had to replace one of the beams for the roof as well as the whole wall and garage door”

“We experienced incredibly heavy rain storms starting last Friday which was also when our ceiling started leaking in our primary bath. We live in a new construction home and contacted the builder who sent out a roofer. The roofer said the issue was caused from a nail that fell through and that he caulked it. I was under the impression he would be coming back to finish repairs once dry but the builder is saying the repair to the roof is complete. The builder is also saying that a broken seal and t”

Unfortunately it is not :/ These answers have been very elucidating

“Yes for the shower in the attic above a restaurant done entirely by a part time handyman.”

“You could be right. It could also be anything else in the bathroom. Its the toilet 80% of the time. Open the ceiling and actually trace the leak. Water takes the path of least resistance and can move strange ways. No one knows until you actually open tbe ceiling and look.”

“It’s outside, neighboring house 8’ away is the closest thing to it. No overhangs. Bottom story of two stories. A few feet away from an open hillside behind it. Installed to code by licensed plumber. House is on top of a hill where if there’s a breeze, we get it. Doesn’t seem like fresh air is a problem, but I’m open to any ideas. (The clamps on the cover are because I have to hard reset it every week) https://preview.redd.it/8xsff7o5f7th1.jpeg?width=3024&format=pjpg&auto=webp&s=e5e52”

“Great! Thank you! When we were going through the plan he said it would be 1 vent pipe that goes through the roof. How many vent openings should there be that go through the roof?”

“You have to cut a hole in ceiling and see what's leaking up there. Then have it fixed. Its only going to get worse”

Oh my goddd.. thanks for your advice

It will be fine. Probably go away on its own.

“it's sloped towards the main stack that goes through the roof, so that a small puddle about a half inch deep forms at the base of the stack”

“Our furnace no longer uses this chimney, but we have noticed that water is leaking from the roof, down the pipe and into the basement (on the outside of the pipe) whenever it rains. I'm not sure how long this has been going on, it could be a while and we didn't notice! My husband and I are not very handy so we called a roofer but he said that he would need the chimney removed first and then he can patch the hole. Do you think that we could just reseal the bottom of the chimney ourselves?”

“Seven years ago I had some foundation work done and afterwards had a static water test done which there were a few resulting repairs. This was one of those repairs. We had a lot of rain this year and last week ended up with the blockage and failed repair. Had it located and started digging. How should I repair this? Should I rebuild the same section with a longer vertical? Should I use Ferncos again or something else? submitted by /u/shakygator [link] [comments]”

“Hey everyone, I noticed a spot in our bathroom that would indicate some type of water damage. I have already called a roofer to get someone out to insure nothing is leaking or repair it if it is. I hopped on the roof to check for myself and took a few pics. My first concern is whether these exhausts/pipes should be capped in some way. Could this cause a leak? Let me know if anything else jumps out. submitted by /u/PeteRosesBookie [link] [comments]”

“Thank you for clicking on my post. :) My neighbor above me had plumbing issues and my strata hired a contractor to fix my bathroom ceiling. They came 4 times to patch the hole. Once to fill the hole with drywall and mudding. Visits 2 and 3 were just mudding. The last visit was to tarp the area, spray "popcorn ceiling" from a spray can, and brush paint a few areas with stain cover paint. No coat of paint was applied to go over the fixed patch. The cost was $2,500 Canadian ($1,800 usd).”

“It looks like I may have a leak somewhere in my second floor bedroom walls. On the other side of the wall is the bathroom and shower. I also want to note that above my ceiling is the roof. We got the roof done last year and I don’t think it’s the roof leak but I can’t be too sure. Any Advice on how to start this repair? submitted by /u/Namttiw9 [link] [comments]”

“pics Purchased a house, and it wasn’t until we got our first heavy heavy rain that we noticed a leak coming through our ceiling. Here is the section of the roof above the leak. I’m guessing this shoddy patch job the previous owners left us has failed? It’s supposed to keep raining hard for the next few weeks, is there a temporary fix to hold it until I can get a roofer out? submitted by /u/imdrukn [link] [comments]”

“Leaks from that gasket which I believe it’s a neo-loc rubber gasket, after doing some research.”

“Relatively new homeowners here. We’ve been here for 2 years and this one area of our roof above our bathroom has given us trouble since almost day one. Anytime there’s heavy ish rain or windy rain, we get a dribbling leak in the bathroom (pic 2). We’ve had: - handyman 1 said it has to be from the structure in the bottom left of pic 1 (bad pic). He caulked it with black caulk or tar - roofer 1 said he identified the problem and caulked it - roofer 2 said it had to be from the vent area and caulke”

“We've had zero plumbing issues in our house for years until a month ago when we had a roof replacement. In the same week we had a washing machine leak where the drain ejected itself forcefully from the standpipe and leaked all over the laundry room and through the ceiling. The week after we had a main sewer line back up which ejected sewage waste out of our ground floor bathroom toilet, sink and bath tub after emptying a bath upstairs. Plumber came out and scoped 90ft in to our mainline to f”

“Left wall is house, door leads to mud room, right wall is garage. First home, and found water damage in the house under the end gutter that’s circled and at the point where the house and mud room meet. Any recommendations? There is no gutter between the door and the green box causing water to fall onto the walkway (we plan on removing the walkway and adding a French drain). We discovered that the edge of the gutter flows into the house. I had 2 roofing companies give a free estimate saying I nee”

“Howdy all, Our bottom floor toilet and tub are leaking water. The toilet from the mounting bolts on the floor and the tub from the drain. I am in a two story town home and the upstairs toilet is directly above the downstairs toilet. I believe it's a stacked line, but I am not sure if that is the right term. Learned a lot in the last day. Upstairs toilet and shower drain just fine, but then we get water flowing downstairs. The downstairs toilet flushes about as well as it usually does, which”

“So, let me get this straight. It's 2026 and there are still flat roof drains that get clogged with debris? And it causes thousands of dollars worth of damage when the water can't go down the gutter drain? I'm starting to think it's a conspiracy by roofers and repairmen to keep mechanical innovation away so that the repair money keeps coming in. There's still no mechanical solution? I can think of about ten new mechanical device inventions that can help unclog roof drains: 1)”

“Kitchen sink is leaking from the bottom of the sink basin. Was wondering if the entire sink basin needs replaced, or just the connecting parts leading up to the pipes underneath? I appreciate any feedback! submitted by /u/Aydenrw13 [link] [comments]”

“Since ya’ll have been so generous in trying to help I really appreciate it. The water was dripping when the unit was OFFovernight after running from that pvc on the roofline. It’s way too high for me to get up there. Once it stoped dripping from there is when I have the water leaking from inside ceiling below.

“Something just happened to our ceiling in the past few days and I can’t figure out what’s causing this. It’s been raining for a few days. Not heavy rain but the amount is decent over a few days. I just saw these leak stains a few days ago on the ceiling of my living room. Above the living room is our attic where we have our bed. The attic is livable and carpeted. The stains almost make a rectangle if you connect them. Can anyone please tell me what these are and what I should do? I’m happy to sh”

“The ground here is brown/red clay. The leak was pretty bad, but it was somewhere between 8 and 10 inches underground for who knows how long. It was definitely swampy back there. It's been a week, and the ground around the area is still damp, even on the surface. Nothing gets watered back there. How long should I wait before getting concerned that the fix didn't take. The area isn't swampy like it was before, but it doesn't seem to be drying either. submitted by /u/gan”

“I can attest to the internal piping being too old and or clogged. I don’t have a waterfall faucet but recently had to change my faucet out because it had the same flow problem. Now water shoots out like it’s supposed to.”

“My old roof had leaks through either vents or plumbing vent boot, and I want to make sure I won't have the same problem with the new roof. The vent has a screw with a rubber washer. The guy explained that they screw it down to protect against strong winds, and unlike exposed nails, this won't cause problems. The plumbing vent is supposed to be lead. Is the joint between the pipe and the flashing properly sealed? A rubber boot is not required here? submitted by /u/innerthai [l”

Yeah you’re gonna have to point to it.

Mid point of the pvc pipe

Where's the leak?

“my bathroom has had a drip in the ceiling that became a full fledged leak in these last rains? i have included the approximate position of the leak and can’t find any damaged shingles? this makes me think it may be along the flashing? my initial thought is to put some roofing tar along the flashing, but wanted to get an expert opinion first? i have included the initial picture. i swept all the pine needles off. submitted by /u/Distinct_Ad9961 [link] [comments]”

“Is sheet vinyl my only option? 40-50 year old single wide trailer home. The hot water tank had a slow leak. The water settled in the hallway outside the bathroom and rotted the subfloor. Tearing that out and replacing with 3/4" OSB shouldn't be too difficult. My problem is the adjacent bathroom. The house was built with sheet flooring installed under the walls. Then at one point the previous homeowner installed wall to wall carpet. That's been torn out and the tack strips still need”

“You can do it the way you planned. You’ll just need a soffit at the end. I probably wouldn’t move the b vent bust depending on how your basement is layed out you could move the vertical drop to the right side of the b vent. Depending on your budget you could also replace your hot water heater and or furnace with a high efficiency model to eliminate the b vent.”

“Have steady water intrusion in my garage during heavy rains. Previous homeowner re-used flashing during new roof install. No comment. It seems the cause is overflowing/poorly designed/poorly installed gutters feeding into a poorly roofed/flashed/sided area. The water is seeping in through a few nail holes where it runs the length of a few trusses and creates two puddles. Slightly sponge along the area. The plan I have: Reflash the entire first floor where its all janky Replace the plywood + shin”

“Photos are taken from the kitchen looking up. The ceiling is open. What you’re seeing is one DWV system serving two full bathrooms upstairs. The black ABS runs diagonally across the joists and drops down at the back wall to the basement. Because it crosses the joists it hangs below them, which is why there’s a drop ceiling in the kitchen. I want to get rid of the drop ceiling. So the goal is to get everything up inside the joist bays and flush. Some numbers: subfloor to bottom of joist is 7.5 in”

“My house is a failed flip, and I’ve been slowly working my way through the previous “improvements” but I haven’t had to do any plumbing yet. The basement looks like they were attempting to add in another bathroom, there is plumbing for hot/cold water for a sink and shower, but my question is what are these? Are these actually the drains needed for a toilet/shower? Or what do I need to do to confirm what they are? submitted by /u/BlueBearRex [link] [comments]”

“Roof replaced 3 years ago. 1 month after replacement this circled area started leaking (mind you, I specifically called this out to them before signing and asked if they could do something here, either cut the pipe down or boot it or anything, of course said "yea yea we'll take a look"). They came back, tarred the shit out of it and put a little kick out flashing to divert water away from the area. They said it was all good. Now, 3 years later, same leak, same place. Hard to tell b”

“I wasn't aware of the pvc/concrete contact thing, thank you. Roof area serviced by this drain is ~150-200 sqft, plus occasional sump water. Moderate seasonal rainfall (Rochester, NY area). So what are we thinking here, a 12" masonry blade for the reciprocating saw. Cut a square hole big enough to remove the old wye, repair the pvc joint, backfill the hole, cover pvc in sill gasket, pour concrete.”

“I recently started seeing a leak in my garage. It only actually came through the drywall during a downpour, otherwise I probably wouldn’t have noticed it. I’m sure it leaks into the attic above the garage regularly and just doesn’t make it through the drywall until there’s a lot of water. Got up on the roof and it looks like someone put a bunch of roof tar around the leak area. From looking in the attic it is definitely leaking where the roof meets the exterior wall (mostly on left side of photo”

“Since it gets worse after rain, i'd suspect a drainage or groundwater issue. Still worth having a plumber check the lines first before spending money on foundation work.”

“Thanks in advance for helping me figure out how much time and money to put into diagnostic and repair. The problem: We recently diagnosed August water damage in the hall as overflow from the mini-split condensate draining poorly. The leak has been resolved with valve rehung at the required angle by HVAC experts. The resolution: Now that the water source is resolved, we have a drywall expert coming out on Friday to quote the patch work on the lower hall wall. The questions for you guys: There are”
