You WON'T believe what caused this WATER LEAK

[@genesmith4022]

As a plumber myself, when you started cutting into the vanity, I cringed. I would have removed the vanity. This would dry the area faster and better and cost less.

[@VegetaIsBetterThanGoku]

Agreed, cant do a nice repair on that either, gonna have to be replaced regardless. Taking the vanity out takes actually less effort than cutting it and all it takes is some caulking to make it brand new. And yeah its a much faster and more thorough drying process.

[@Yahgiggle]

Totally agree, when he even cut that first hole I was like WTF that's amateur man only remove once you can prove you have pin pointed the area, he was just guessing without thinking first. He did guess right with the nail in the pipe so I will give him thumbs up on that.

[@samueltaylor4989]

That’s why a plumber shouldn’t do any work other than plumbing. WAY more work than necessary to remove vanity, granite counter top AND put it back with caulking, painting and making it not look like patchwork. Holes inside vanity VERY easy to fix and you will NEVER see it.

[@Mote78]

You guys are saying quite the opposite. I’m only a DYI’er but while I like the idea of pulling out the vanity to gain better access and help ensure thorough drying, that would be a much larger job and put the bathroom virtually out of commission for a week or more because of drying. I had this happen in the kitchen and I removed the floor and back wall of two cabinets and removed the Sheetrock and insulation. Let it dry for 2 weeks then repaired. The kitchen was always functional and no one would know of the repair unless I emptied the cabinets and showed them. Plus, I would have needed a strong helper or two to pull the granite off and then later again to return it. That would have been a bigger nightmare.

[@duradim1]

I got two more cents. I think Matt cut the first hole because that allowed access behind the tub which also was against the outside wall where the leak was draining to. But the origin of the leak was perpendicular to that spot. Cutting a hole into the bottom of the vanity was useless but cutting a hole into the back of it is a toss up. Remember, we have hindsight to criticize how he did it. Myself though, I think removing the vanity would had been my first choice, but the leak was really behind the toilet. So my work would have been wasted? The fact is finding leaks can be tricky, messy and expensive. That is a cost that should be passed on to the customer because contractors don't have crystal balls, well at least ones that work, and you got to start somewhere.

[@Iceaxehikes]

As a plumber myself I can say a few things that my tribe could have done better. Where is the sleeve to protect the copper pipe from the concrete? Why was the pipe brought up near the face of the wall. There should have been a nail plate, installed by my tribe member, over any area reasonably expected to get trim. As for the wood butcher tribe; they hit our pipes all the time, the smelly bunch of drunks. Carry on.

[@jaisvikt]

Would that sleeve for the pipe be a kind of wrap? Agreed, shelf life for that pipe in concrete was greatly shortened by knuckle draggers.

[@Iceaxehikes]

jaisvikt normal would be for the water pipe to be sheathed in foam insulation (looks like a pool noodle) and further sleeved in a continuous plastic tubing material from where the pipe enters the form or slab until it exits without a joint or break in the plastic sleeve below the level of concrete to be poured. Water pipe, even insulated and sleeved, is NEVER to be secured to rebar or any reinforcement or concrete forms themselves. The plumber puts in his own stakes or wooden jigs to secure the pipe in position before the concrete is poured. Waste pipe is wrapped in foam (handicap wrap) anywhere it is within concrete. This is how it is done properly and passes California bay area code. Edited for typos clarity.

When I moved into my new to me house, I replaced all the trim and floor boards. Fifteen years later, the carpet in our family room was slightly damp in one small area and would not dry out. Turns out I drove a nail into a pipe that was running along the drywall. Not in the middle of the wall or anything, right along the drywall in a notch in the stud. No plates or anything to protect it. It took that full 15 years for the leak to develop.

As a Texas home builder since 1977, I learned the hard way after a trim carpenter drove a nail into a water line similar to your friends home, but the coated nail gun nail didn't leak for the first year or so after the home was finished, sold and then occupied. The nail eventually rusted loose and the leak developed and was spraying water just like this one was. After fixing the problem, I began having my plumbers install metal protection plates (taller than the planned base boards) over vulnerable areas where water pipes are coming up out of the slab. The metal plates are thick enough to prevent nail gun nails from penetrating the plate.

[@brandonbrownlee3348]

One thing you can do for the immediate purposes, and it actually will hold up possibly indefinitely, but it's not elegant, is you can just grab a piece of bicycle inner tube and a hose clamp. Cut a small chunk of inner tube to fit over the leak and most of the way around the pipe, then hose clamp that inner tube into place. That will stop your copper pipe leak easy without having to leave the water off and you can then have time to figure out what you're going to do for a real fix.

The PVC drain pipe was incredibly located on the 16" so no wonder! Good job Doyle Wilson! (Also, no thanks for the brick chimney that came down: two stories high on a house that has 10' ceilings, where it was only supported by the first floor and NO MASONRY ANCHORS anywhere! We were lucky it didn't come down on someones head! Every house I know of in this area (Hunter's Chase) has had to replace their chimney!) The contractors laughed at the shot up pipes in two places when they got the layers off down to the studs, then shot through the same drain pipe again as they nailed the sheathing. Luckily it was discovered and marked more carefully before the Hardie went back on!

This video reminds me of an unfortunate yet rather funny story that happened to me about 6 months ago.... I built an addition for a client who is also a pretty good friend of mine. The addition was a 16x24 room that was to become his master bed/bath. After we framed and enclosed it the plumber and electrician came and did their respective jobs and we did the drywall, flooring, and trim. The homeowner, whom I've known for 20+ years, isn't the most handy guy I know but he wanted to tackle the walk-in closet shelving himself to save a few dollars and to give himself what we both thought was a fairly simple little project. At about 11:30 p.m. that Saturday night I got a phone call from him telling me he had a situation. I came over the next day and saw what had happened. In the process of mounting a shelf bracket for a shoe rack to the closet wall he informed me that the 2 1/2" torx screw he was using would go through the sheetrock and then stop and spin. His solution was to grab his drill bit set and drill a 1/8" pilot hole through what anyone in the trades business knew to be a nail plate. He realized his mistake pretty much instantaneously and frantically scrambled to shut off the water. I assured my rather embarrassed friend that it wasn't too difficult of a repair and told him I could fix it fairly easily. It was about that time that I noticed the wall that housed the (open) pocket door also had a number of shelves hung on it. I suddenly came to the realization that I never thought to explain to him the importance of screw length when dealing with a pocket door wall. I got the feeling he wanted to just walk away from the problem and close the door on it, but he couldn't........because he screwed it open.

Low tech, old-fashioned (?) trouble shooting method: I would have drained the fresh water system. Connected an air compressor, and run the pressure up to roughly 60 psi, nothing excessive. Then used a $50 video camera and a $10 microphone and an old surveillance DVR ($100?) to find the hissing of air hissing out of a hole behind a wall. Highly accurate, because that hiss is high frequency sound and can be triangulated to point of origin. This minimizes damage incurred during trouble shoot.

I cringed watching him cut a knarley hole in that textured bedroom wall... if he had cut a nice 6x6 square hole it could have been filled with a paintable inspection cover...you always need those for behind a tub area anyway... I know exactly what this feels like...just had a siding crew shoot a hole in my hvac line and bleed all the freon out of the compressor on an HVAC unit...wall had to be cut back out...cost $1000 in R22 freon on that legacy system to recharge it and resolder the line.

Many negative comments of this video. I personally found it was helpful to me. I own many rentals, i do my own renos and maintenance and i appreciate this type of videos. Everyone does things differently.

[@virgil3241]

It was helpful to an extent, but some of the replies that arent mean are as well helpful,. as in these days with a snake cam, you can do a lot less damage to find the issue. And as well, he hasnt answered how that are would even be dried up and repaired after the fact. You cant just fix the leak and then cover it up, after leaking that long, how much water damage and rot occured. Never showed the dry out process or replacement if needed.

[@PlumbingExplained]

Cuts a hole see’s wetness immediately says “we found the source of the leak”

[@throttlebottle5906]

so, run around with a silly tool, then randomly cut holes in walls without even looking nor feeling around for obvious signs. this falls under "nailed it" :)))

[@Vics251]

He’s pretty neat, the plumbers I’ve known in the past would have used a Mel hammer to smash holes everywhere ! ⚒

[@jimh2061]

Good find! I had a similar situation but it was a pinhole leak. Makes a real mess. I usually go directly where the copper lines are in the walls and evaluate how bad the area is. I cut a hole where it's the most saturated.

[@jesseback3536]

Dude. They make super cheap, but decent, gooseneck cameras with lights now. Start with the tiny 1" hole and go from there.

[@agualotus]

Hey Matt, fun fact, here in Minnesota we are not allowed to have an exterior wall as our wet wall. (Wet wall being the term we use to describe which wall we run our plumbing)

[@hobarbriggs4371]

Great video! Excellent approach to finding the problem and explaining your thought process.

[@NGinuity]

Same exact thing happened to me about 9 years ago. Nail drove through the wall into a pipe. Sealed until it rusted and then sprang a leak. Ruined the carpet in one room and figured out the copper pipes were not roughed up through the wall correctly in the process. I've learned that crap work like that usually isn't a loan circumstance in houses. If you find it once, beware of more.

[@thymark]

If she is dry, then the nailing pattern is complicated.

[@MrBababuwi]

she claims she likes it

[@ottoroth9377]

I agree with Matt...concrete is tabu on copper pipe, when i poured a slab around soft copper on a pressure line, i placed a pvc sleeve over the pipe. Now, if i bave to build again, i will run 2inch pvc, then run pex thru the pvc..in case of an issue, can pull out the pex, and replace it.

[@ernestbywater411]

I think you should invest in a cheap endoscope for checking inside cavities.

Great video,reminded me of a basement remod where cheaper laborers were hanging wood wall paneling A wet rug in the bedroom made me think toilet seal leak,but no.I saw where one guy ignored the seams and studs ,and nailed into the paneling to take the bow out.Of course the supply lines to the bathroom were right behind it AND spraying into an outlet box.Lucky,it was a pinhole and the sheet rock was not soggy yet. Another one was a drip in the corner of the ceiling of the half bath on the first floor.That one was tricky ! After a day of cutting holes I found that the floor trim installer used those 3 inch finishing nails and had punctured the 4 inch PVC vent stack.After ten years the nail rusted away and condensation no longer went up,it came out that tiny hole and ran downstairs.

What a good friend you are ❤️

[@obsoleteprofessor2034]

I had a dead electrical outlet on a back to back kitchen on some new construction. I had power to the plug on the opposite kitchen and I thought I had fished the wire to the wrong unit. Turned out that the stucco guys had nailed through and sheared my hot completely and the nail caught the opposite unit wire and energized it via the nail.

[@samsno3667]

Nice video. And yes ... I believe it. What an awkward place to fix the leak; can't be easy going under that vanity especially with that cross bar to service that leak. The first leak you didn't show but just the repair patch (would have loved to see what and how it was leaking) but for sure the camera video captured the nail that punctured the pipe.

Put some flex-seal tape around the pipe. Fix her right up. LOL

[@LarsonFamilyFarm-LLC]

Few year back, re-roofing.... a roofing nail hit my low-pressure A/C line and bled out. Can't braze up near roof sheathing....found a red-liquid-1/2 twist product that does a/c line- high pressure...worked like a charm....no leaks all these years. Again, i "finessed" and pulled the a/c lines away from the roofing and re-insulated.....careless home-builders. Oh, and then these was the washing machine drain line....the drain line's clean-out cap was conveniently removed by the drywall-er since the cap's turn nut was in the way...nice! Had mold on my drywall.Drywall was essentially capping off a 3" drain line!!!!...for about 7 years before we found it.

jeseuess... I thought that was someones hair hanging over the lens of a go pro.

[@CirilloFrank]

Matt, You sure did a lot of damage before finding the problem. First thing to always look at is the water meter to see if its a supply side leak. That said, you could have been a lil more patient with your fancy moisture detector tool, but that would have made a boring video. I sure hope you did your friend a solid by upgrading his vanity for him! Keep up the great building science vids....

[@nicholashartzler2205]

As a homeowner - easy repairs man - I bought a stethoscope from Walgreens and I can find most any pressure leak in minutes. No not near as fancy as FLIR but it only cost $9.95. Of course, I can't non-pressure leaks!
