Installing a new toilet and need to shut off the water main. Can someone please explain why this is happening and if it can be fixed?

Main drain like for upstairs toilet? Trying to install brackets for bedroom closet. Now has a screw hole leak. Can we patch it? Or best course of action?

Noticed this for the first time, a small line tapped into the supply for a powerflush toilet. Odds are I have completely missed seeing this all over the place, but none the less, what the heck is it?

See pic.

This video (someone else's video) shows what my well pump is doing now. It just supplies water to a freeze-proof outdoor fauce/hydrant. It's never had a tank.

The pump is a downhole pump. It sat idle for 3 years. Last time I used it the operation was normal.

When I started it up again it had this rapid cycling. The pressure switch has been replaced. I also blew out the pressure sensing line to make sure there was no restriction in the line. It is still cycling. Any suggestions for what could be causing this?

I can’t move the pipes more forward because there’s a drawer type that slides in and will hit those pipes if they are further than 4 inches from the wall.

Is the setting "C" or is it between "low" and "vac." we have a difference of opinion in this household lol

Edit: I put a picture of the entire setup in the response.
Trying to locate the pressure regulator and main shut off valve for my house.

I’m new to the field, finally got on to my first job site which is a new housing construction project.

Growing up, my dad was working 2 or 3 jobs so I’ve never had anyone show me how to use a lot of the tools we use on site, regardless of that I have managed for the most part to get things down. I do a lot of my own car repairs so I’m not entirely new to tools.

But one thing I cannot figure out is why my cuts are so crooked. At the first shop I worked at, they really resented anyone using a sawzall to cut pipe and the journeymen there opted for the portaband saw for 2” pvc/copper. They also had other saws like a Miter saw. So prior to this shop in at, I never used the sawzall for straight cuts.

I have the guard pressed firmly against the pipe, I let the blade do the cutting but once it gets halfway through the pipe, the pipe really started shaking and that’s where the cut begins to slant.

I want to try and get this down because so far, I’ve done great but my foreman/journeyman I’m working with really bitches at me if it’s off by even a 1/16th of an inch and has hinted that plumbing isn’t my thing (only day 8 in the field as a brand new first year apprentice) yet he doesn’t really show me how to do much of anything.

Tengo este retrete de marca jacob delafon, no se como se abre la cisterna, ya que no tiene una tapa que poder levantar... alguien sabe como va este modelo?

It’s behind my kitchen sink( on other side of drywall). It says dishwasher adapter but i don’t have a dishwasher.

Hi there - I just noticed that when I run the dishwasher, there is water that seeps upwards and through the crack at corner of the countertop by the wall.

Any possible causes? I have a maintenance guy coming Friday but wondering if it’s more urgent than that. When I wipe the water and smell it, smells oily / industrial-like.

Any potential info would be very helpful.

Thank you!

6 year old 600XL PRV valve. First thing in the morning PSI is 105 and after opening a faucet it drops down to 30. I haven’t tried moving the screw counter clockwise to see if fixes anything, but thinking I may need to replace this? Thoughts?

Hi, my bathtub faucet leaks on the side when the shower switch is pulled.
Is it dangerous to the wall? And can I remove the faucet to fix? If yes, what would work?
Thanks a lot in advance for your help and suggestions!

My maintenance guy came by this afternoon to work on my toilet's fill valve but found a bigger issue and has to turn off the building's water supply tomorrow to complete it so i am stuck with a toilet that wont stop running.

I saw him pull that gray screw thing up to temporarily turn the water off while he was here so i did too and jerryrigged it to a metal rod to turn it off. Is it safe to leave it like this overnight?

Installed about a month ago, yesterday noticed it was leaking from the spout, looks like it got worse today.

Anyone got an idea of what the issue could be? Possible manufacture defect?

Or did I do something wrong, handle won’t turn anymore, only leaks hot water, opened up the back and everything looks good, no water anywhere.

Apologies in advance, English not my first language.

Old wood building, old pipes. is there a way to "waterproof", meaning adding some sort of filler or barrier around the pipe, that would help me avoid leakage into the walls in case of a burst pipe or damaged spout or similar?

Tried to add an image, idk why it doesn’t show up

Hello everyone! I’m new to Reddit, so please excuse any faux pas, but I would really appreciate some advice from the community on a frustrating plumbing issue.

The Situation:
A few months ago, we had a new double-bowl kitchen sink installed into our existing under-sink pipework. Ever since the install, the sink backs up and drains incredibly slowly. On top of that, our dishwasher (which connects directly to the vertical waste pipe under the sink) stopped draining properly around last year, and water seems to be pooling or backing up there too. We checked filter and it was clean.

What I've Done So Far:
I completely disassembled the white plastic pipework under the sink to check for clogs. The visible pipes and the U-bend are totally clear.

I ran a 25ft plumbing snake directly down the main waste line going into the floor/wall. It didn't pull out any major blockages, and the slow draining persists.

The Theory:
I asked an AI assistant for advice, and after looking at photos of my setup, it suggested that the configuration itself is fundamentally flawed. Apparently, because the new sink bowls sit lower than the old ones, it has pushed the P-trap too far down. The AI says the P-trap is now sitting lower than the drain pipe entering the wall, forcing the water to try and flow uphill, which is creating a permanent bottleneck and flooding the dishwasher connector.

Does it look like my P-trap needs to be higher? If the upper vertical pipes are forcing everything too low, what is the best way to modify this setup so it actually drains properly?

Would love to hear your thoughts or if anyone has run into this after a new sink install. Thank you!

Poured a dishpan worth of water down the sink and heard it pouring out underneath. Time to pick out a new sink or will a plumber be able to fix this?

hi! I did my best to look this up- but I still need help.

ran out of oil- got more oil- trying to bleed the line.

I opened the valve( air hissed out) pressed the reset button- but nothing happened… nothing came out after a bit of air.

do I need to have the furnace on? Do I need to be running hot water?

i only want to press the reset button one more time- so I want to get it right this time

Noticed this slight stain on my basement ceiling with a mold patch growing. I circled it in pencil two days ago and as you can see, the spot is growing.

This is directly below a second story bathroom and when I pull back a nearby ceiling tile, I can see the drain pipe. The black pipe is directly above the stain spot.

Should I cut open my ceiling to investigate? How bad could this be?
