V1 100 Gallon Slim Vertical Water Tank — Buffer & Chemical Tank
Available in stock (40)
The original EPW 100-gallon slim vertical water tank: the buffer tank our truck skids were built around, made thicker and heavier than anything else on the market so it does not split or sag under 830 pounds of water. Slim enough to stand against the headboard of a half-ton truck and lose only a foot of bed.
- 100 gallons in a 48 in. wide x 12 in. deep x 39 in. tall footprint, 65 lb empty
- Double-thick walls rated for water and for sodium hypochlorite storage
- Two lids for fast filling and easy cleaning
- 41 inches between the bottom cutouts for strap placement
- Pair two together for 200 gallons or run one for water and one for chemical
V1 or V2? The V2 100 Gallon Slim Tank is the same size and price with internal supports that stop the walls from bulging when full. The V1 is the proven original and the one we recommend for bleach storage. Either way, add the V1 tank straps and the buffer tank plumbing kit.
Common questions
Will this fit a half-ton truck?
Yes. At 12 inches deep it stands against the front of the bed in an F-150, Silverado 1500 or Ram 1500 and leaves the rest of the bed for the skid. Full, it is about 900 pounds, well inside a half-ton's payload with a single-machine skid.
Is 100 gallons enough for an 8 GPM machine?
Yes, on normal residential water. It covers the gap between what the spigot gives and what the pump pulls through a full house wash. Two machines or hot water, go to two of these or a 200.
Does it ship free?
No. Tanks ship by freight. Call 503-403-6185 or email orders@expertpowerwash.com with your delivery address and whether it is residential (lift gate needed) or commercial (dock or forklift) for a quote, or pick up at our Oregon City store, Monday through Thursday, 8am to 4pm.
