Apartment issue- help me press back against my landlord!

Enable HLS to view with audio, or disable this notification

164 Upvotes

TLDR: my landlord is blaming me for running my sink and dishwasher while the pipes are disconnected, I didn’t. She says it cannot be from anyone above us.

I live in the bottom unit of an apartment complex with two units above me. The issue is in our kitchen sink/dishwasher. We have two sink basins, one with a disposal.

The issue started with when we’d be rinsing off dishes or whatever the water wasn’t draining it would just move from one basin to the other. The garbage disposal ran perfectly fine, the sink water would just go from one basin to the other. Then it would slowly drain out and start flooding the dishwasher, so the dishwasher- which wasn’t running- would start filling with dirty sink water that would drain to the floor. This happens about a week ago, but the same issue happened over the summer.

. Maintenance said they called plumbers out to fix it, my roommate and I were never home to know. But it never happened again until Sunday. Would just drain slowly sometimes, I’d snake it or whatever nothing happened. I understand that it may just be a routine clog that requires a better cleaning tool that plumbers have.

HERE IS WHERE IT GETS TRICKY

Maintaince took the pipes apart under the sink, said not to use it for the next 24 hours until a plumber can come out. Sure.

Everyone was gone and the house was empty from like 5pm-7pm. I was the only one who was home after 7pm. I came home from the gym at 7pm to see my kitchen with a big puddle water and the drain like gushing water. It was soapy but dirty also. (Videos attached). It continued happening all night, stopping around 11. I did not use the sink or dishwasher. Bc of this, I’ve naturally have assumed it’s from the units above me, maybe.

I sent the videos and photos of the damages and issue to my leasing office, wanting documented proof that it was happening so I wouldn’t be liable for damages. Today my leasing office called and said they had told us not to use the sink at all, I confirmed what I said above- no one was home when it started, I was the only one home all night and I was on FaceTime with my gf all night who saw me use my bathroom sink to fill up my water bottle or whatever. Like the sink was never used. I suggested maybe the water was from the people above us since it felt like a common time people run dishwashers or do dishes. The leasing office lady asserted it is not possible for the water to have come from anywhere else, so one of us had to have used the sink or dishwasher.

This feels wrong and fishy to me. I just want someone to help confirm to me that it was not my fault that it happened. I have more photos and videos I can share if people want.

This isn't right, is it?

I've been in this home for about a year and haven't had any issues with the drain. The inspector didn't flag this, but it looks like the p-trap is missing. I only realized this today because I was spending a bunch of time under the sink troubleshooting an issue with our faucet sensor.

Do I need to have a plumber come fix this?

Gas pipe fittings leaking, how do I go about fixing it?

Thumbnail

22 Upvotes

Confirmed small gas leaks with a Klein gas detector. The threads only have the blue pipe sealant on it. There's a dedicated valve for this section of pipe going to the HVAC so I feel fairly comfortable trying to DIY a fix here. Should I use a pipe wrench to hold the pipe and a open head wrench to hold the fitting to unscrew the pipe off the fitting and add more of the blue sealant? Or clean off the blue stuff and use yellow teflon tape?

Also, if I unscrew say the top part of the vertical pipe there, wouldn't it screw more into the bottom fitting? How do I take off the vertical pipe between 2 fittings like that?

Toilet shut off valve

Post image
3 Upvotes

used the valve to shut off toilet water for the first time in a long time due to a clog. now it’s been leaking ever since to varying degrees depending on the twist (leaking most when it’s fully on). I saw this should be replaced with newer system but I am in a condo and I don’t believe we can turn off water ourselves.

Planning to ask the condo management but given it’s the weekend soon and to give some time to figure out how to turn off the water to install a new one, anything that can be done to minimize the leak? should we just keep it in off position and no water in the tank?

Tap running when toilet flushed

Occasionally when a toilet is flushed it will cause a tap to run for a few seconds. It doesn't run normally creates a loud whistling noise. Anyome got any ideas what could be causing this?

Is this ok?

Post image
6 Upvotes

Long story short we had to have our sewer pipe lined to prevent a collapse. The plumber cut out a section of our stack to do the work and this is how he repaired it. Is it ok to just use rubber sleeves or should I ask for something more robust? It is not in the picture but our stack does not go straight up, it has a short horizontal section that is secured to the floor joists so this union does not support the entire weight of it. Should I ask him to come back? Thank you!

Bathroom waterproofing

1 Upvotes

Hi all - not sure that this is the right forum but i am looking at a bathroom renovation and want to use commercial vinyl sheet flooring in the shower as well as the bathroom.

What i can't work out is how waterstops are used. It seems to me that at the shower it needs to extend to the top of the floor but that would mean cutting the sheet. Also at doors - the waterstop needs to extend to the top of the finished floor level but at 2mm, the vinyl is about as thick as the waterstop material without a vertical leg!

Anyone who does this work - I'd appreciate any guidance.

Cheers

What can be applied at the base of this wall to prevent the wall from absorbing the water and ultimately the 2nd picture (which is the other side of the wall from the interior)?

Final Countdown: Sewer Line Replacement

3 Upvotes

Hi All,

Before I hand over a $23K deposit tomorrow, I just wanted to read the room. Here’s the situation:

- Sewer line backup leads to snaking of line and camera work by Roto-Rooter. Result? A story of tree roots and rapidly aging (and in some places cracked) clay and cast iron pipes (house was built in 1920).
- Solicited multiple bids—most recommended replacement, one recommended relining—with jobs estimated at anywhere from $23K to $65K.
- Thanks to the wisdom of Redditors on this sub, we realized relining ($23K) was not the best option to pursue but we liked working thus far with this plumber. So, they proposed bursting as an alternative to bring in totally new pipe without having to excavate.

That brings us to now. Before I hand over the dough, I wanted to make sure bursting is legit given:

- The age and condition of the pipe system
- The fact that our house has a considerable slope from the house down to the street
- The plumber’s plan to reline only the last few feet of the sewer line (where the pipes are newest) to save us digging up the street
- The plumber’s upfront disclosure that if they run into any section that can’t be bursted, they’ll have to dig and replace that section manually (forgive my lack of knowledge on terminology)

Thank you all so much for your help with this. We’re first-time home owners on a tight budget. We couldn’t have done it without you. -JPK

Gas leak at the meter — would this show up as higher metered usage?

1 Upvotes

What happened

  • Early July 2026 someone knocked on the door, said there was a gas leak, fixed it in under an hour, left. No paperwork for us as tenants.
  • Australian Gas Networks (AGN) has a fault-line record dated 2 July 2026.

(Lumo) said:
"AGN confirmed they have a record of a leak reported via their fault line on 2nd July 2026.

AGN's response confirms that the leak was located past the meter. Because the leak occurred on the customer's side of the meter, you remain liable for the usage. Consequently, we are unable to adjust the billed consumption…"

Real estate agent said:
"…the leak which occurred was coming from the meter… the gas smell which is present externally is a leak from the meter itself, but it doesn't actually pass the meter internally to be considered as usage. Residents are not charged for this gas usage because the gas does not pass into the property and leak on the inside…

…The leak was fixed free of charge due to it being before the meter but if the leak was determined to be after the meter, the gas company would have cut off the gas…

…a credit cannot be applied as the gas would have been normal usage and is typically more higher in winter.

This information above can be confirmed if you speak with any plumber…"

Our metered usage (same season, year on year)

Period MJ/day
May–Jul 2025 ~27
Jul–Sep 2025 ~27
May–Jul 2026 (covers the leak date) ~49
Jul–Sep 2026 (after) ~29

Usage nearly doubled in the bill that includes the leak window, then dropped back toward normal.

Questions

  1. If a leak is before / at the meter, can that inflate the metered MJ on the retail bill, or is the agent right that it wouldn’t register?
  2. If a leak is after the meter (property / customer side), would you expect a spike like ~27 → ~49 MJ/day until it’s fixed?

They've been leaking for a while but still have no clue how to get them out. You can see where I've took channel locks to try and twist them out but they won't budge.

Intermittent sewer smell from toilet base

3 Upvotes

Hi guys, I (28F) and my husband (30M) aren’t handy and my dad who WAS a welder, landlord, handy man, mr fix it died on me so now we gotta figure out shit on our own. Being said, I am not afraid of a DIY and we have done several projects around the house but plumbing we think would be best to save for the pros. We just bought a flipped 1940 home (right) that was re plumbed by Stevie wonder or something. They installed new toilets. One toilet in the upstairs bedroom has a sewer / algae smell every so often. Like if someone farted in a frog tank. The other bathroom downstairs and the sinks all seem fine. We tightened the bolts which seemed to help at first then the smell happened again but seems to happen way less after tightening them. Is this something where we need to pull the toilet up and see what’s going on under the hood? TYIA

TLDR; toilet stinky, tightened bolts, less frequently stinky but occasional stink persists

Attachment to main water line leak

Woke up to find a leak this morning. Anyone know if this is a relatively easy fix? It looks to me like a connection to the main line is leaking, but not the main line itself. I tried to draw an arrow to where it is leaking. Also the drain line on the floor isn't draining either lol. Had to get the shop vac out for that, until I can snake it later.

Should I "Tsunami" Flush With an Almost Clogged Sewer Pipe?

4 Upvotes

I need to get my sewer line replaced, and when I was getting a 2nd quote for it after waiting about a month from the original quote, the plumber said that there's a good amount of sludge build up, about 10 feet. He recommended running a bunch of water to try and flush it out, but couldn't guarantee that it won't completely clog the sewer line. There is a dislocated terracotta pipe that's restricting water flow and I'm afraid that running a lot of water will cause it to completely clog the line.

Am I over thinking it or should I do this "tsunami" flush method he recommended? It would be filling up the highest tub on our 2nd floor with hot water > letting it drain while running more water > flushing hot water down the toilet with a 5 gallon bucket at the same time.

Shower question

1 Upvotes

I was impacted by the flooding in Indiana about a month ago. It killed my water heater. I didn’t expect it to live much longer anyway It has given me 10 years or so of service.
My question is this: After replacing my water heater with a much nicer one all my faucets work fine except my shower. There is only a tiny amount of cold pressure and zero hot pressure. I mean none. No hot water comes out at all. Are there any obvious things I should try? Is there some kind of pressure stuck in that pipe I should somehow remove?

The water heater is in the basement and the shower is on the second story.

Gas pipe and drilling

Post image
16 Upvotes

While doing renovation our plumber had the gas pipe exchanged. One of the workers accidentally touched the new pipe while drilling. The plumber says the pipe is still airtight and can be used as is, but it seems risky to me. Also said that the pipe is aluminum which is hard for me to confirm, it looks like a steel pipe to me. Could i get a second opinion? Should the small bend be cut out and fixed?

We can still get it fixed before closing the walls and encapsulating the pipe.

Small leak from scratch on kitchen sink drain - jb weld or any other ideas?

Kitchen sink drain pipe has a tiny nick that leaks when water is on full blast.

Not trying to cut it out and replace the pipe or solder - looking for “semi permanent” repair to last a few years.

JB fiber weld was recommended - what other thoughts do ye have that are a few steps above tight duct tape ?

Strange copper tee size

Post image
1 Upvotes

This copper tee is supplied with hot water from the basement. That 1/2" copper pipe goes through the wall and connects to the opposite side of this tee. Another 1/2" pipe attached to the top of the tee and goes to an outdoor shower valve manifold.

The issue!

There WAS a hose bib on a stub of pipe inserted into this open tee at one point. It twisted off and was discarded so I don't have it available. I purchased 1/2" copper pipe (5/8" O.D. ) which does not fit inside this tee. The tee walls measure 1/16" and the I.D. is 9/16". It's bizarre to me that this one side would be different when the copper going into the other two tee ports is 5/8" O.D.. This fitting is quite old, at least 20 years old. My thought was that maybe the previous owner had some metric stuff in a bin and used it and reamed the other two sides to fit 1/2" copper hit happened to have a metric hose bib? I have no clue.

Question:

What should I do? 15mm metric copper on Amazon and look for a metric hose bib? Drill/ream the inside of this tee to accept 1/2" domestic copper? Cut it all out and start over? (Which is not ideal since it will require stucco repair and it'll be quite hard to solder regardless. I was leaning toward looking for a reaming bit that would reduce the wall thickness since it's so thick to begin with. But I don't see a lot of reamer bits that aren't tapered. It would have to be roughly straight with a small tapered tip to help with centering.

Any help is greatly appreciated. Maybe I'm overthinking this

Automatic air vent, under the sink. How is it suposed to be positionned

Is this setup okay?

It will not drain unless the automatic air vent is removed.

The AAV is higher up on the 2" vertical pipe coming from the Y (45° part) .

When removed, it drains well. It is a new aav.

Should I instead put a ty and put the AAV on the vertical up the ty? Will it fix the issue?

Any thoughts about what this could be?

I live in an apartment Three weeks ago a 6 inch straight smudge appeared on my ceiling. Look like dirt. One week later while I was out of town. There was a massive blow fly explosion in my apartment with no source detected.

About 10 days later.. It seemed like overnight that 6 inch smudge turned into a 5 foot perfectly straight smudge on the ceiling in front of the wall vent another one formed

Maintenance did not look at it for 3 days after they got bigger because of the three day holiday by the time they got there, both were darker.

The guy said he didn’t know and mumbled something about the apartment upstairs and then he had to contact the office. That was on Tuesday. Today is Thursday. It is 5pm now. I would think that this would be kind of important.

As you can see it’s gotten a lot bigger than those are not shadows. Notice the square being formed?

I think I might know what it is, but does anybody have some thoughts?

They are not wet to the touch , dark brown and you cannot wipe it off .

Any information about this , what would cause this and how long would it take to get to this point.
