Full Details why this is the perfect 100 Gallon Water Tank for Pressure Washing

Heavy-Duty Poly Construction for Long-Term Use

Made with UV-stabilized high-density polyethylene (HDPE), this RomoTech 100 gallon tank is built to last. It’s rustproof, corrosion-resistant, and made to handle non-flammable liquids like water, cleaning agents, and agricultural chemicals. Whether you’re pressure washing equipment, storing irrigation water, or watering livestock, this water tank holds up in tough conditions—indoors or outdoors.

Designed for Pressure Washing and Mobile Water Systems

This tank is a great match for mobile pressure washing rigs. The horizontal square design offers a low profile and added stability during transport. With a 3/4″ NPT outlet, it easily connects to hoses, pumps, or pressure washer inlets. The large 5-1/2″ screw-on lid (5″ hole) makes refilling quick and mess-free.

Accurate Water Level Monitoring

Never guess how much water is left in your tank. The molded-in gallon and liter markings allow for quick and easy level checks. This helps you plan water usage on the job and ensures you’re always ready to clean, spray, or irrigate.
