Fresh and waste tanks, and the ratio between them

Everything on a mobile unit starts with two tanks, and the relationship between them is set by rule rather than by preference.

The waste tank must be larger than the fresh tank. Typically by a clear margin, so a unit cannot run out of waste capacity while it still has water to use. Fitting a bigger fresh tank without matching the waste side is the commonest way to fail an inspection.

Size for the service, not for the truck. A coffee unit and a fryer based menu use completely different volumes. Running dry halfway through a lunch rush is a plumbing decision made at build time.

Waste has to be dumped at an approved point. Usually a commissary, never a storm drain and not into a yard. Keeping records of where and when you dumped is part of the paperwork, and inspectors do ask.

Tanks have to be cleanable and accessible. A tank boxed into a cavity nobody can reach will not be sanitised, and an inlet that cannot be inspected is a finding waiting to happen.

Sinks, hoses and hot water

The fitted equipment is where most units either pass comfortably or need work before they trade.

A separate handwash sink is not negotiable. It is distinct from the warewashing sinks, it needs to be reachable while you work, and it needs soap and towels at it. Using a compartment of the wash sink for handwashing is a standard finding.

Warewashing is usually three compartments plus drainboards. Wash, rinse, sanitise. Where a unit is too small, an approved alternative has to be agreed rather than assumed.

Hot water has to be there on demand and at temperature. A small unit with an undersized heater runs out during service, and that is both an operational problem and a compliance one.

Use a potable rated hose and keep it that way. White or blue, stored so the ends never touch the ground, and used for nothing else. A garden hose is not acceptable for filling a fresh tank.

Backflow protection at the fill point. You will be filling from taps you do not control, and the protection is what stops your tank contaminating somebody else's supply, or the reverse.

How a call plays out

Tell us whether the unit is being built, being brought up to standard, or has already failed something. We will give you a straight answer about what is a fitting and what is a rebuild.

We cover Lackland, Leon Valley, Somerset and the rest of west Bexar County. Mobile units are a small job in a tight space and we price them as their own thing, we work to your service days, and we will point you at the commissary conversation when that is the real answer.
