The plumbing guide
Are you getting a health permit? That answers most of this.
A cart water system is four parts: fresh tank, pump, sink, grey tank. The sink is the part a county has an opinion about.
7 sections · 2 pumps · 3 sinks
Start with the sink. A permit decides which one.
Cut the panels first and the county can send the cart back.
- Price
- Backbone $899 stainless, $799 black steel. The simple pump is quoted with the build.
- Time
- About 3 weeks on the Backbone, before it ships.
The short answer
Two builds, two starting points.
Nobody is inspecting this cart.
Pick the sink that fits the counter. Two connections or fewer and no water heater: the simple mounted pump. Anything more: the Backbone.
Your county has to sign off on it.
The sink stops being your choice. We recommend the 9×9×5 stainless with the gooseneck faucet. Counties that require wash-rinse-sanitize get the three-compartment ABS.
Get your county health department's requirements before you talk to us. We can't design to spec without them. The permitting process covers the rest.
The pump
Two pumps, and the water heater decides.
They split on how many connections you need and whether a water heater is in the plan.
Budget-friendly

- An install guide written for cart builders, not plumbers
Espresso, rinser, sink and hot water all run at once.
The sink
The part your county has an opinion about.
Health code varies by county, and each county runs its own health department. Ask yours before the panels are cut.
Moli Mini Handwash Sink
Compact handwash
For tight counters where a full sink isn't required.
- Smallest sink we fit
- Ask us for dimensions and permit status before you design around it
Most popularHealth dept. friendly
Stainless 9×9×5, gooseneck faucet
Most recommended for permitted builds
The gooseneck clears pitchers and carafes. Most health departments accept it.
- Stainless steel basin
- Exact dimensions get confirmed on your schematic
Health dept. accepted
Three-compartment ABS
Wash · Rinse · Sanitize
For a full wash-rinse-sanitize workflow, which many counties require of mobile food facilities.
- ABS plastic
- Three basins
- Check the requirement with your county before ordering
Pitcher rinsers
Rinsers, and the NSF question.
Two shapes. Check one thing before you pick.
Standard Pitcher Rinser
Two sizes available
Two sizes, for different cup and pitcher diameters.
- Not NSF rated
- Ask us about current availability
Trending
Rinser + Mini Faucet Combo
Larger platform, integrated faucet
A larger rinser with a small faucet that drains into the rinser pan. One drain instead of two.
- Not NSF rated
- Larger footprint — confirm counter space
Knock box
$75 · Add-on
The cutout sits on the left, below the pitcher rinser. The rinser moves up to make room.
If your permit says NSF
Our standard rinsers are not NSF rated. NSF-certified ones start around $250. If your permit requires NSF, tell us when quoting and we'll source one that meets it.
Tanks & hot water
What comes standard, and what does not.
- Fresh water
- 5 gallons. Standard in every plumbing package.
- Grey water
- 5 gallons. Also standard.
- Larger tanks
- On request.
- Custom sizes
- Sizes and configurations for specific health code requirements. Tell us when quoting.
- Custom layouts
- For permitted builds. Every spec signed off before production.
- Hot water
- Instant heater, preinstalled on your sink, hot and cold side. $350.
One constraint worth reading twice
The Hot Water Package works with the Backbone only. The simple pump isn't recommended with a water heater. If hot water is in your plan, even a season from now, buy the Backbone once.
Building it yourself
If you bought the flat pack, the plumbing is in the box.
The Pack Flat DIY bundle includes a Backbone kit, pitcher rinser, mini sink with faucet, and the drainage and tubing. Water jugs and the knock box are separate add-ons.
