You have pex for water lines? I hate that stuff. Copper all the way for me. Contractors use it because it’s cheaper and faster for them to install which results in better margins for them. Leaks for you later.

and the ice maker is full


Right before covid hit - pretty sure it was Mardi Gras Morning 2020 - I woke up, stepped into the kitchen, and heard a *squish* noise when I stepped onto the lvp there.

I walked around some, and heard more squishing. There was a water leak somewhere.

Turns out there was a pinhole in the icemaker line that was slowly spraying water behind the fridge, running under the wall, and getting under the flooring. I had to tear out all the flooring in the house because it spread so far.

And the icemaker was working just fine the whole time the waterline was leaking.

Can you directly look at and feel (sometimes the water travels on the underside of the pipe and you can’t see it but you can feel it) the entire condensate line? Remove insulation if you have to.



Yes, there is no outward sign of condensate leaking. I have directly traced the line out to where it elbows down and goes into a wall. Can’t see what happens after that though. That is why I am tempted to break some Sheetrock. I didn’t see anything leaking in the attic, and there is no staining of the ceilings anywhere either.

My house piping is all copper.

This is something like what I have going on as well. Pretty much a whole bedroom carpet is soaked. I am resigned to the fact that I will have to change the carpet out….but I have to get the leak stopped first.

A month ago my water valve on the back of my fridge/freezer sprung a leak. 1 drip every 2-3 seconds. It must have been there for a while because on the other side of the wall is our closet and the carpet was soaked pretty good.

Luckily I have LVP so no damage in the kitchen and I was able to pull the carpet, dry, and replace the pad underneath. The fridge part was $30 and 10 minutes to swap out.

Overall, the biggest PITA was this all happened 2 days before going out of town so I was on a time crunch. All in all, it wasn't bad and could have been much worse. It definitely makes me want to integrate some leak detectors into my Home Assistant setup though.

If you aren't getting mold yet, you still have time. Grab a corner and pull up, borrow/buy a dehumidifier, and cut out the wet padding.

You should be able to see on the concrete where the leak is coming from then determine what's going on.

Thanks for the response.

Did the wetness start at the edge of a wall?

I also say pull up the carpet. Gotta trace the water backwards now.

Call a leak detection company. It’ll run you about $400 and they can usually tell you exactly where it’s coming from.

You can do a lot of damage investigating on your own.

A lot of insurance companies use American Leak Detection. It’s a franchise company with locations all over.

Time to drop back and punt.

Rather than tear all of my shite up, I have decided to call American Leak Detection. I did not know such a service existed!

The saga continues….

That's a load of crap. Copper can leak just as much as anything else is bad workmanship is involved. I use copper and PEX all the time without issue, prep work and using the proper materials and practices is everything.

Water bill last month was the monthly minimum, so that further reinforces the theory that is not a water leak. I’ll still have the leak detection company check it out when they get here.

All that is true but you can’t say PEX will outlast copper all else being equal.

Anyway, OP, make sure you post the resolution when you find out.

Is it wet near an exterior wall? My neighbor had wet carpet in a room every time there was a heavy rain because there was a crack in the slab.

How large an area of carpet?
Is the room adjacent to a bathroom/kitchen/utility room?
Where is your water heater located?

6 weeks ago, I had some foundation work done.


Could be a cracked pipe in the foundation.

Good call. Vibration from concrete work can crack a pipe.

Primarily located in a carpeted bathroom seeking under the wall to an adjacent bedroom.

Water heater is located in the attic. Central AC unit is above the bathroom.

It has not rained here in over a month.

I had a leaking pipe in the slab years ago. Went in the kitchen late one night when everything was quiet and heard a faint hissing sound that seemed to be coming from the sink. If I pressed my ear against the walls I could hear it in other parts of the house as well like water was running. Did not get water in the house from it though or a high water bill. Leak detector guy found the pipe and we had that section of copper pipe lined with pex pipe so no digging.
