Description

In Indiana, a charge of medium‑density polyethylene enters a rotational mold and emerges as a precise 16 gallon water tank—a horizontal domed reservoir designed for everyday reliability. The natural, translucent wall lets operators verify fluid level instantly, while molded gallon and liter markings provide an exact read. Outdoors, UV‑stabilized poly resists fading and warping; in service, it won’t rust or corrode. A 5‑1/2" lid (5" opening) and easy‑tighten cap simplify refills, and a built‑in bulkhead fitting with a 3/4" NPT outlet makes fast work of draining, siphoning, or hose connection. Molded tie‑down channels accept saddle straps so this portable water tank rides securely as a truck bed water tank or trailer water tank, ready for farm chores, job sites, and water tank for car detailing setups. Rated for non‑flammable liquids to 140°F, it serves confidently as a potable water tank, a rugged water storage tank, or an RV water tank for extended trips. Made in the USA, it’s engineered for cleanability, durability, and dependable performance wherever you need compact capacity and square‑profile stability.

  • Good tank
Works well for my softwash setup, bleach and water friendly

  • Well made, easy to add faucets If needed
well made and solid construction. I have a second faucet near the top so it can drain into my rain catchment system. Mine is being used for the discharge from a reverse osmosis filter, to not be wasteful of water.

  • Perfect tank for RODI water! Perfect tank for RODI water!
I have upgraded the plug with bulkhead. So easy to install and No leak. Easy to check the water level. Before I used brute for RODI water. The lid is big open wide. " I don't know why people are complaining to install with different plugs. There is NOTHING easy in life" This is a COMMON SENSE. " The most I love this tank is, able to see through water line & how much water in tank. It has mark water line 4, 8, 12 & 16 line in the front, I can't really see the water marked so I marked with Black marker on it. Thank you for making an easy ways to see water line. ... show more

  • Good tank, Bad bulkhead fitting Good tank, Bad bulkhead fitting
It’s a good tank, the plastic bulkhead fitting leaked. The hole in the tank is 1 5/8”, so I ended up getting a 1 1/4” brass bulkhead fitting to fix the leak.

  • 16 gal.
The best tank ever. I bought this for a diesel fired heater for my shop. Fits EXACTLY in the space I needed. Strong enough for a shut off valve.
