Plumber tool storage setup: a stack that survives wet jobs

Short answer: build a plumbing stack around water and weight. Cordless tools and batteries go in the rolling base, the press tool and jaws get their own protected case, fittings go in clear organizers one size per bin, and anything wet or dirty lives in its own sealed box. Then dry it out once a week, because water is what ruins a plumbing kit.

Plumbing is hard on storage. You kneel in water, set boxes down on wet floors, and pack up fittings that are still dripping. An electrician’s stack can get away with open drawers full of mixed tools. A plumber’s stack has to keep water out of the things water ruins, and keep dirty out of the things customers see.

Split the truck kit from the carry-in kit

Before you buy or move anything, decide what never leaves the truck.

The stack is the carry-in kit: what you need for most calls without walking back to the truck. If you are hauling a box into every house and only opening it once a month, that box belongs on a shelf.

Stack order, bottom to top

Remember that on most systems a lid box under other pieces cannot open until you unstack it. Put the box you open least at the bottom of the lid-box run, and keep the drawer unit high.

You can open a sample layout like this in 3D: see the sample plumbing stack. It is an example we built to show how the app works, not a stack from a real user.

Press tool and jaws

A press tool and a set of jaws are some of the most expensive things on a plumbing truck. Treat them like it.

• Keep the case. Press tools and jaw sets are often sold with a fitted case. If yours has one and it fits in your stack, use it. If not, a foam-lined lid box does the same job.
• One jaw, one slot. Sort jaws by size and profile so you are never reading tiny markings under a sink.
• Nothing on top. Do not let a pipe wrench or a box of fittings ride on the jaws.
• Follow the maker. Inspection, cleaning and service intervals come from the press tool manufacturer. Write the next service date in the drawer notes.

Record the serial number of the press tool, each jaw set and every battery while you are at it. Our tool theft inventory guide covers what to record.

Fittings you can count at a glance

Fittings are where plumbing stacks fall apart. A bin of mixed elbows and couplings costs you five minutes on every call.

• Use clear-lid organizers and keep one type and size per bin.
• Label the edge of the lid as well as the top, so you can read it with organizers stacked.
• Group by material and joining method: press, push-to-connect, PEX, threaded, sweat. Do not mix systems in one bin.
• Keep a restock list taped inside the lid or in the drawer notes in the app. When a bin hits one-third full, it goes on the list.

Wet and dry, clean and dirty

Give anything wet or dirty its own sealed lid box: hand augers, closet augers, plungers, rags, gloves, and anything that touched waste. Clean and dry them before they go back in. Keep meters, batteries, chargers, paperwork and the clean drop cloth you put down in a customer’s house well away from that box.

Some modular pieces carry an IP65 rating for dust and water resistance. Milwaukee lists an IP65-rated weather seal on PACKOUT lid boxes such as the 48-22-8424 tool box, and DeWalt lists IP65 ratings on TOUGHSYSTEM 2.0 boxes. DeWalt’s deep compact tool box page notes the rating applies when the lid is closed, with the latches locked, sitting upright.

Three things follow from that:

1. A rating is for that piece, not the whole system. Check each piece you own, including drawer units.
2. It assumes the lid is closed and latched. An open box on a wet floor is just a box.
3. Dust and water resistant is not the same as waterproof. Do not leave a stack sitting in standing water.

Water that does get in has to come out. If a lid box gets wet inside, open it and let it dry before it goes back on the truck. Rust starts in the boxes nobody opens.

Truck vs carry-in

On the truck, the stack should be strapped or mounted so it cannot slide when you brake. In the house, it should roll to the job and come apart at chest height. If you work in a lot of basements or upper floors, keep the carry-in stack shorter and split it into two trips rather than one tall, heavy stack.

Do the stair test before you call the layout done: load it, roll it to the truck, lift it in, and carry the top pieces up one flight of stairs. If that hurts, move weight down or take a piece off.

Fuel, torches and chemicals

If you carry a torch kit, fuel cylinders, flux, solvent cement or drain chemicals, follow the product labels, the safety data sheets and your employer’s rules for storing and transporting them. Keep them out of the drawer unit with your hand tools and away from the wet box. When in doubt, ask your shop how they want it carried.

The weekly dry-out

1. Open every box and drawer. Dump receipts, scraps and broken fittings.
2. Pull out anything wet. Let it and the box dry before closing it up.
3. Wipe down pliers and wrenches. A light coat of oil on exposed steel helps.
4. Restock fittings from the truck.
5. Charge every battery.
6. Update the stack in the app if anything moved or got replaced.

Fifteen minutes on Friday beats finding a rusted set of pliers on Monday.
