Water Tank - 150 Gallon ***2-3 WEEK LEAD TIME***
-
The Detail King 150 Gallon Water Tank is a UV-stabilized poly water tank built for mobile detailers chasing dealership and parking-garage accounts out of a pick-up truck, van, or trailer rig. It carries roughly 50% more water than the popular 100-gallon size: enough to add a few extra vehicles per route without committing to the footprint and payload of a 200-gallon tank. Molded tie-down slots on both sides keep the tank secure in transit.
Highlight specs:
- 150 gallons when full
- UV-stabilized linear polyethylene
- 3/4” NPT molded outlets (customizable)
- FDA & NSF approved (resin compliance FDA 21 CFR 177.1520)
- Molded tie-down slots on both sides
- 46” L × 30” W × 29” H footprint
- 2-3 week lead time (built to order)
Who this is for
- Mobile detailers chasing dealership and parking-garage accounts that need 10-15 vehicles cleaned per visit
- Detail shop owners scaling a mobile route past the 100-gallon ceiling without jumping to trailer-only rigs
- Two-operator rigs where one tank has to feed two wash stations through the day
Sizing guidance
- 60 gallon is right for part-time detailers doing 3-4 vehicles a day
- 100 gallon is the working-day sweet spot for solo mobile pros doing 8-10 vehicles
- 150 gallon (this product) is the upgrade for commercial-account routes and two-operator setups
- 200 gallon is worth it if you routinely fill a full dealership lot or run steam plus extraction off the tank
- 330 gallon is for fleet-contract work and dedicated detail trailers
Water usage planning
A typical full exterior wash uses 10 to 15 gallons per vehicle. Factors that push you to the upper end: wheel cleaning, engine bay rinsing, two-bucket wash method, or hard-water runoff requiring extended rinse.
- Sedans / small SUVs: ~10-12 gallons per vehicle, so 12-15 vehicles per 150-gallon tank
- Full-size trucks / SUVs: ~12-15 gallons per vehicle, so 10-12 vehicles per 150-gallon tank
- Adding interior extraction: add 2-4 gallons of additional rinse water per vehicle
If you’re also running a heated carpet extractor off the same tank, subtract the water used for interior details from your wash count.

A 150-gallon tank suits commercial-account routes and two-operator rigs. At 10 to 15 gallons per vehicle, it covers 10 to 15 vehicles per fill: more headroom than a 100-gallon, without the payload of a 200. Size it to your busiest wash day, not your average one.
-
A UV-stabilized poly supply tank like this one, filled at home or a client tap and carried in the truck bed, van, or trailer. The molded tie-down slots secure it in transit, and the 3/4" NPT outlets feed a tank-fed pressure washer or in-line pump. UV-stabilized poly lets you stage it full without mold worry.
-
Most route detailers get 10 to 15 vehicles from one fill. An average wash burns 10 to 15 gallons on a car, truck, SUV, or van, and vehicle size and condition decide where in that range you land.
-
No. This tank is built from UV-stabilized linear polyethylene, so you can leave water in it for periods of time without worrying about mold or algae. That means you can fill it and stage the rig overnight in a truck bed, ready for an early start, without dumping and refilling each morning.
-
Not always. Most residential and many commercial pressure washers must be force-fed from a pressurized source, so they will not draw from a tank on their own. With one of those, add an in-line pump to feed the washer. A machine built for tank-fed use draws water directly, no extra equipment needed.
