To break out sheetrock or not?

Submitted by sacamano79 t3_z5tss3 in DIY

Need to know if I should break out my drywall and replace insulation.

I was installing a shelf in my laundry room and drilled a hole in a 1ā€ water line on the other side of the drywall. Water came shooting out and I shutoff the water main a minute or so after it happened. Although I shut the water off quickly, I know a ton of water ended up in my wall because I have water stains on the sheetrock on the downstairs level and water is seeping out below the baseboards.

My plan is to cut a hole in the down stairs drywall, rent a blower, and pull air through the wall to dry it out, but Iā€™m not sure if this is enough. Everything I research online about drilling a hole in a water line only talks about the repair of the line (I have that handled), and other searches only speak to dealing with long-term leaks, not a one-time leak.

Would a one-time (albeit high volume) leak warrant a full drywall and insulation replacement?

Imho no. Dry it properly and you should be good to go

What kind of insulation? If it's fiberglass or an open cell foam, rip and replace. If it's rock wool or closed cell, you can dry in place.

For the sheetrock, you will need to remove some to assess the damage behind anywhere you see signs of water damage and to allow it to dry better. Anything that has lost its integrity should be replaced as well. If you can stab through with a fork, replace it.

Outside of that, it's more about what else to remove to make repairs/drying easier. One large hole is easier than 5 small holes.

Also, get yourself a good stud finder that finds pipes and wires. It's way cheaper than the repairs you are looking at.

If you dry it properly, it should not be an issue.

Edit: consider pouring ethanol in then pulling air through. Ethanol is a very good water dispersant.

Is this a thing people do? How do you avoid accidental fires?

Power isolation and proper drying.

The ethanol evaporates pretty quickly. Shouldn't be a problem unless you point a kerosene heater at it after pouring it.
