Injecti-Dry Direct-It IN System

About this equipment

The Injecti-Dry Direct-It IN universal air-mover adapter converts a compatible centrifugal air mover into a targeted wall and cavity drying system. Its 17 outlets direct air through small hoses into approved wall or ceiling cavities and underneath cabinetry.

Direct-It IN system included with the rental

• Universal adapter housing
• Three 1.25-inch × 50-foot Direct-It hoses
• Seventeen 5/8-inch wall penetrators and 17 hose cuffs
• Ten end-cap plugs and carry bag

Plan cavity drying before drilling

The system is designed for approved locations where a 5/8-inch access hole can be made. Property-owner approval, utility awareness, safe work practices, and a confirmed drying plan are required before modifying walls, ceilings, cabinetry, or hardwood assemblies. HBS confirms the air mover, accessories, quantity, rental period, rate, and fulfillment.

What the manufacturer says the kit does

Injectidry Systems describes the Direct-It IN as a universal air mover adapter that works with most common air movers and dries up to 22 linear feet as packaged. Its 17 ports send air through 1.25-inch hoses to 5/8-inch wall penetrators in wall and ceiling cavities and under cabinetry.

You do not have to use all 17: Injectidry's FAQ says unused ports on the adapter can be left open.

When cavity drying makes sense

Water that runs down inside a wall, under a vanity, or into a kitchen cabinet base can stay trapped there long after the room feels dry. Pushing air into those spaces can help dry them in place instead of cutting out drywall or removing cabinets. It is only for clean-water (Category 1) leaks, and it works best when drying starts quickly.

Typical cases include a kitchen or vanity supply line that leaked into the cabinet base, a water heater that leaked into the wall of its closet, and a wall that wicked water up from a wet floor. EPA says to dry water-damaged areas within 24 to 48 hours to prevent mold growth, so set up as soon as the leak is stopped.

Can the wall be dried in place?

EPA's water damage table says wallboard may be dried in place if it shows no obvious swelling and the seams are intact, and recommends ventilating the wall cavity if possible. That is the job this system does. The same table also sets the limits:

• Drywall that is swollen or has open seams should be removed and replaced.
• Wet fiberglass and cellulose insulation should be discarded and replaced, so an insulated wall that soaked through usually has to be opened.
• Wet paneling should be pried away from the wall to dry, and EPA notes that vinyl wallpaper and paneling can trap moisture underneath like a vapor barrier.
• Materials wet for more than 48 hours fall under EPA's mold guidelines instead.

How the system is set up

• The adapter mounts on a compatible centrifugal air mover.
• The Direct-It hoses in the kit connect the 17 outlets to wall penetrators placed in the cavities you want to dry.
• Small 5/8-inch holes, often hidden behind a baseboard or cabinet toe kick, let the air into each cavity.
• A dehumidifier in the same room removes the moisture that comes out.
• Track progress with a moisture meter at the same spots each day.

Step by step

1. Confirm the leak is stopped and the water was clean.
2. Map the wet area with a moisture meter, and with the FLIR thermal camera if you rent one. Mark each wet section of wall.
3. Pull the baseboard where you can, so the holes are hidden when it goes back on. Under cabinets, work through the toe kick.
4. Check for wiring and plumbing before you drill. Wires run to outlets and switches, so keep holes away from them.
5. Drill a 5/8-inch hole into each wet stud bay. Studs divide a wall into separate cavities, so air sent into one bay does not dry the next.
6. Seat a wall penetrator in each hole, connect the hoses, fit the adapter to the air mover and start it.
7. Run a dehumidifier in the room and read the same marked spots each day.
8. When the readings match the same material in a dry area, take out the penetrators and close up the holes.

Electrical and drilling safety

• If water reached outlets, switches or wiring inside the wall, turn off power at the main breaker only if you can reach the panel from a dry spot without touching anything wet. If the panel is wet or you would have to stand in water, stay out and call an electrician, as the CDC advises.
• Have a qualified electrician inspect the system before the power goes back on and before you power any equipment, as OSHA's flood cleanup guidance directs.
• Plug the air mover into a GFCI-protected outlet in wet areas; OSHA says GFCIs must be used in all wet locations.
• Get the property owner's approval before drilling, and do not drill into tile, stone or finished cabinetry you are not prepared to repair.

When cavity drying is the wrong tool

Blowing air into a cavity moves whatever is inside it. Stop and call an appropriate experienced professional when:

• The water came from sewage, a toilet backflow, or outside floodwater or storm surge. The IICRC S500 standard classes sewage as Category 3, and EPA says not to use fans before you have determined the water is clean.
• The water came from a dishwasher or washing machine overflow, which the S500 standard places in Category 2.
• You see or smell mold, or the wall has been wet for more than 48 hours.
• The wall or ceiling is sagging, or wiring inside it got wet.

HBS does not offer mold remediation or contaminated-water cleanup, and neither a rental nor HBS's water-only drying includes restoration or repairs. For a clean-water leak, ask HBS about its separately scoped water-only drying at (772) 677-1735.

Equipment that works with Injecti-Dry

• A compatible air mover to drive the adapter; HBS confirms which one goes with your rental.
• A commercial LGR dehumidifier to remove the moisture coming out of the cavities.
• A Protimeter moisture meter to find the wet bays and confirm when they are dry.

Common questions

What does the Injecti-Dry system do?

It attaches to a compatible centrifugal air mover and pushes air through hoses into wet wall cavities, ceilings, and under cabinets, so you can dry areas a room fan cannot reach without removing drywall or cabinets.

Do I have to drill holes?

Yes. The system uses small 5/8-inch access holes, usually placed where they are hidden behind baseboards or toe kicks. Get the property owner's approval and check for wiring and plumbing before drilling.

Is an air mover included?

The Direct-It IN kit is the adapter, hoses, and accessories. HBS confirms which compatible air mover goes with your rental when it confirms the request.

How much wall can one Direct-It IN kit dry?

Injectidry Systems says the kit dries up to 22 linear feet as packaged, using 17 ports that feed 5/8-inch wall penetrators. Each wet stud bay needs its own hole.

Can I dry a wall that has wet insulation inside?

Usually not. EPA's water damage table says wet fiberglass and cellulose insulation should be discarded and replaced, so an insulated wall that soaked through generally has to be opened.

Do I have to use all 17 ports?

No. Injectidry's FAQ says unused ports on the adapter can be left open.

When should I not use cavity drying?

Do not push air into a wall wet with sewage or a toilet backflow, outside floodwater or storm surge, or washing machine or dishwasher water, or one that shows mold, sagging, swelling or open seams, or an electrical hazard. Call an appropriate experienced professional for those walls; EPA says not to use fans before you know the water is clean.
