Plumbing Truck Stock List: What to Keep on Every Service Van

A plumbing truck is not just a vehicle. It is a small warehouse that has to work under pressure.

When it is stocked well, the plumber walks back to the van, grabs the part, and finishes the job. When it is stocked badly, the job stops over a wax ring, a shut-off valve, a cartridge, a supply line, or one fitting that should have been there.

This guide gives you a practical plumbing truck stock list for service vans. It covers the parts, tools, equipment and safety items most plumbing teams should consider, plus a simple way to organize and restock each truck with plumbing inventory software.

Quick answer: what should a plumbing truck carry?

A plumbing service truck should carry the parts and tools needed to complete common jobs without a supply house trip.

At a minimum, most plumbing vans need common pipe and tubing, PEX, PVC and copper fittings, shut-off valves, supply lines, toilet repair parts, faucet repair parts, drainage fittings, wax rings, water heater parts, sealants, drain cleaning tools, hand tools, cordless tools, inspection equipment, PPE, bins, labels and a restock process.

Why plumbing truck stock matters

A missing part costs more than the part. If a technician drives 25 minutes to a supplier, waits in line, drives back, and then restarts the job, the real cost is labor time, fuel, schedule delay, and sometimes customer confidence.

Most plumbing inventory problems look small: the last wax ring was used yesterday, the angle stops moved to another van, the press fittings are in the warehouse, the drain camera is with another technician, or the spreadsheet says "in stock" but nobody knows where.

That is why truck stock should be managed by location. A warehouse count is not enough. You need to know what is inside Van 1, Van 2, the warehouse, and sometimes the job site.

How to use this plumbing truck stock list

Do not copy the full list blindly. Start with your most common jobs, then stock for those jobs first.

• If you do mostly toilet repairs, stock heavier on wax rings, flappers, fill valves, flush valves, closet bolts, supply lines and angle stops.
• If you do water heaters every week, stock T&P valves, expansion tank parts, gas connectors, flex lines, dielectric unions, drain pans and common fittings.
• If you do drain cleaning, your drain machine, augers, gloves, drop cloths and inspection camera matter more than extra faucets.
• If you do repipes, pipe storage, fittings, valves, supports and press or PEX tools become more important.

A good rule: stock heavy on small, common, cheap parts that stop jobs when missing. Stock lighter on bulky, expensive or finish-specific items.

Plumbing truck stock list

Use this as a starting list, then adjust it to your service mix, region, brands and call history.

1. Pipe and tubing

Keep enough pipe and tubing for common repairs, not enough to turn the van into a warehouse.

• PEX tubing, copper pipe or tubing, PVC pipe, CPVC pipe where used, drainage pipe and short repair lengths.
• Flexible connectors, ice maker tubing, appliance tubing and gas piping materials if your team handles gas work.
• Common sizes: 1/2 inch, 3/4 inch, selected 1 inch, plus 1 1/2 inch, 2 inch, 3 inch and 4 inch drainage where relevant.

Keep long pipe on a rack or in a clear pipe storage area. Pipe that gets damaged in the van turns into waste.

2. PEX fittings

PEX fittings are easy to burn through during service calls and small repairs. They are also easy to lose if they are thrown into one mixed bin.

• Elbows, tees, couplings, reducing couplings, adapters, male and female adapters.
• Crimp rings or expansion rings, PEX valves, PEX to copper adapters, PEX to threaded adapters and stub-out elbows.
• Separate 1/2 inch and 3/4 inch fittings so the right size is visible fast.

3. Copper and press fittings

If your team uses press fittings, keep them clean and separated. Dirt and damaged seals are not worth the risk.

• Couplings, slip couplings, elbows, tees, adapters, caps, unions and transition fittings.
• Press ball valves, copper repair couplings and threaded adapters.
• Common sizes: 1/2 inch, 3/4 inch and selected 1 inch service parts.

Keep press fittings in lidded bins. Small open bins collect dust, pipe shavings and random screws.

4. PVC, CPVC and drainage fittings

Drainage calls can eat time if the truck has pipe but not the right fitting.

• 90-degree elbows, 45-degree elbows, tees, wyes, couplings, reducing couplings and cleanout adapters.
• Cleanout plugs, traps, trap adapters, tailpieces, extension tubes, slip nuts, washers and tubular drainage parts.
• Kitchen sink drain parts, waste and overflow parts and closet flanges.

Separate pressure fittings from drainage fittings. They may look obvious in the shop, but not when the truck is dark, cold, wet, and the customer is waiting.

5. Valves and shut-offs

Valves are high-value truck stock because they often turn a delayed repair into a finished repair.

• Angle stops, straight stops, quarter-turn stops, compression stops, PEX stops and sweat stops.
• Ball valves, boiler drains, hose bibbs, washing machine valves, gas shut-off valves and check valves.
• Pressure reducing valve parts, vacuum breakers and supply stop escutcheons where common.

Angle stops disappear quickly. Set a minimum level per van instead of waiting until the bin is empty.

6. Supply lines and connectors

Supply lines are small, cheap and used constantly. They should be easy to reach.

• Toilet, faucet, dishwasher, ice maker and appliance supply lines.
• Washing machine hoses, flexible water heater connectors, gas appliance connectors where allowed and braided stainless lines.
• Assorted adapters, escutcheons, washers and gaskets.

Separate toilet, faucet, dishwasher and appliance lines. It saves more time than people expect.

7. Toilet repair parts

Toilet calls are common, and the parts are usually small enough to stock well.

• Wax rings, wax rings with horn, wax-free seals, closet bolts, shims and closet flanges.
• Flange repair rings, fill valves, flush valves, flappers and tank levers.
• Tank-to-bowl kits, bowl-to-floor hardware, supply lines, common gaskets and toilet seats if your team replaces them often.

Wax rings, closet bolts and supply lines should never be "maybe we have one somewhere" items.

8. Faucet and fixture repair parts

Faucet parts are tricky because brands and finishes vary. Stock the common repair parts first, then keep finish-specific items lighter.

• Cartridges for common brands, stems, seats and springs, aerators, O-rings and washers.
• Handles for common repairs, faucet supply adapters, basket strainers, tub spouts, shower heads and shower cartridges.
• Plumber's grease and small repair kits.

Carry enough to solve common repairs. Do not fill the truck with every finish.

9. Water heater parts

Water heater jobs are expensive enough that missing a small part feels especially painful.

• T&P valves, dielectric unions, gas connectors, water heater flex connectors and expansion tank parts.
• Drain pans, drain valves, thermocouples, igniters, elements, thermostats and anode rods if your team services them.
• Nipples, adapters, pipe insulation, venting parts, straps, supports and brackets.

If your team regularly installs water heaters, create a separate water heater install kit instead of picking parts one by one for every job.

10. Drain cleaning gear

Drain work needs its own space in the truck. It is dirty, heavy and easy to mix with clean repair parts if the van is not organized.

• Toilet auger, hand auger, drum machine, main line drain machine, extra cables, cable heads and cutters.
• Drain inspection camera, locator, drain gloves, buckets, drop cloths, trash bags and disinfecting wipes.
• Plungers, approved drain maintenance products and a manhole hook where relevant.

11. Hand tools, cordless tools and consumables

Every plumber has preferences, but the truck should still have a baseline.

• Channel locks, adjustable wrenches, pipe wrenches, basin wrench, strap wrench, tubing cutters and PVC cutters.
• Screwdrivers, nut drivers, Allen keys, utility knife, tape measure, torpedo level, flashlight, hammer, pry bar, deburring tool and test plugs.
• Hammer drill, impact driver, sawzall, press tool, PEX crimp or expansion tool, transfer pump, wet/dry vacuum, work light, chargers, batteries, bits and blades.
• PTFE tape, pipe dope, PVC primer, PVC cement, silicone, plumber's putty, thread sealant, abrasive cloth, rags, wipes and trash bags.

Treat blades, bits and batteries like inventory. A tool without the right blade is just weight in the van.

12. Safety gear and customer protection

A stocked truck should protect the technician and the customer's home.

• Safety glasses, gloves, disposable gloves, ear protection, masks, hard hat where needed and high-visibility vest.
• Disposable coveralls, knee pads, first aid kit, fire extinguisher, caution tape and wet floor signs where relevant.
• Shoe covers, drop cloths and floor protection.

A plumber who has shoe covers, drop cloths and clean work habits looks prepared before the repair even starts.

The practical restock system

A plumbing truck stock list only works if someone maintains it. The usual mistake is making a huge checklist, printing it once, and never updating it again. A better system is simple and repetitive.

Set minimum levels per truck

Do not use one minimum level for the whole company. Van 1 might handle mostly drains, Van 2 might handle water heaters, and Van 3 might do general residential service. They should not all carry the exact same stock.

These numbers are examples. Your actual levels should come from service history.

Use a simple A/B/C stock rule

You do not need to manage every part the same way.

Standardize bins and labels

A truck stock list is easier to follow when the truck is labeled. Use clear names like "1/2 inch PEX elbows" instead of broad labels like "PEX." The point is to help the plumber, the apprentice, and whoever restocks the truck.

If you use QR codes or barcodes, put them on bins first. It is often easier than labeling every tiny part one by one. You can create simple labels with the free barcode and QR generator.

Create a truck restock routine

A simple routine works better than a perfect system nobody follows.

• Daily: replace parts used that day, charge batteries, remove trash, put tools back, flag low-stock bins and check PPE.
• Weekly: count fast-moving parts, refill bins to minimum levels, check drain equipment, clean drawers and review missing tools.
• Monthly: compare truck stock to service history, remove dead stock, add parts that keep causing supply runs and update min/max levels.

What not to keep on every plumbing truck

A stocked van is good. An overloaded van is not. Be careful with too many faucet finishes, rare cartridges, oversized pipe that almost never gets used, full fixtures that sit for months, broken tools kept "just in case," old fittings from brands you no longer use and job leftovers mixed into normal stock.

Every item on the truck should earn its space. If it is used often, stock it. If it saves an expensive return trip, consider stocking it. If it has not moved in months, question it.

How to decide quantities

There is no universal quantity that works for every plumbing company. A one-person residential service van does not need the same stock as a multi-tech company doing water heaters, drain cleaning, remodels and emergency calls.

1. List your top 20 most common jobs.
2. Write down the parts used on each job.
3. Mark the parts that caused supply runs.
4. Set minimum levels for those parts first.
5. Review actual usage every month.
6. Adjust by van, not just by company.

How to track truck stock without making the team hate it

The system has to be fast. If a plumber needs to open a laptop, search a spreadsheet, edit a row, and hope the file syncs, the system will not last.

A better workflow is simple: label the bin or part, scan it from a phone, choose the truck or job location, update the quantity, and let low-stock alerts handle the restock list.

Start with bins if labeling every item is too much. For example, scan "Wax rings - Van 2," adjust quantity from 6 to 4, and if the minimum is 5, it appears on the restock list. That is enough for most small teams.

Spreadsheet vs inventory app for plumbing trucks

A spreadsheet can work at the start. It is cheap, familiar and easy to edit. It starts breaking when more than one person updates it, several vans carry the same parts, stock moves between trucks, job leftovers come back, nobody updates the file in real time, and the office cannot tell what is actually on each van.

A plumbing inventory app helps when each van needs its own stock count, and the team needs a quick way to update items from the field. HomyScan is built for that inventory layer. You can create each truck as a location, import your current list, scan barcodes or QR codes from a phone, and set low-stock alerts for the parts that keep delaying jobs.

You do not need to replace your dispatch, invoicing or accounting tool just to track truck stock.

Simple restock workflow for small plumbing teams

Final thoughts

A good plumbing truck stock list is not about carrying the most parts. It is about carrying the right parts, in the right truck, with a restock routine the team will actually follow.

Start with the items that stop jobs when missing: wax rings, angle stops, supply lines, common fittings, valves, toilet repair parts, faucet repair parts, water heater parts, drain tools, PPE and floor protection.

The truck should answer one simple question before every call: do we have what we need to finish the job? If the answer is hard to find, it is time to move beyond memory and spreadsheets.
