RomoTech 50 Gallon Square Water Storage Tank — Translucent Polyethylene, UV‑Stabilized

The RomoTech 82123919 is a 50‑gallon, horizontal square polyethylene water storage tank built for rustproof outdoor use and straightforward filling, draining, and transport.

This compact, domed reservoir is designed to hold potable water and other compatible non‑flammable liquids for farms, trailers, job sites, irrigation systems, pressure washers, RVs, and emergency reserves. Rotationally molded medium‑density polyethylene with UV stabilization resists corrosion and sun damage, while the natural translucent finish and molded graduations let you check levels at a glance. The tank’s low, stable profile and molded tie‑down channels make it suitable for mobile installations when secured properly.

How easy is it to fill, inspect, and drain this tank?

Filling and cleaning are simplified by a 5‑1/2‑inch lid with a 5‑inch opening that provides ample access to the interior. A built‑in bulkhead fitting with a 3/4‑inch NPT outlet enables straightforward draining, siphoning, or connection to standard hoses and fittings. Visual checks are fast thanks to the natural translucent material and the molded gallon and liter graduations.

• 5‑1/2" lid with 5" clear opening for filling and maintenance
• 3/4" NPT bulkhead outlet for draining and hose attachment
• Natural translucent construction plus molded gallon/liter graduations

Will it hold up outdoors and during transport?

The tank’s rotationally molded polyethylene resists rust and chemical corrosion, and UV stabilization helps prevent sun‑related degradation in outdoor settings. Its horizontal, domed shape keeps the center of gravity low for improved stability in truck beds, trailers, and on flat surfaces. Molded tie‑down channels accept saddle straps (not included) to help secure the tank in mobile installations.

• UV‑stabilized medium‑density polyethylene for outdoor longevity
• Low horizontal profile for better stability on vehicles and trailers
• Molded tie‑down channels for secure strap mounting (straps sold separately)

What liquids and temperatures are appropriate for this tank?

This tank is intended for potable water and compatible non‑flammable liquids only; it is not suitable for gasoline, diesel, or other flammable fuels. The manufacturer specifies safe contact temperatures up to 140°F, but you should confirm chemical compatibility before storing any solution. Always support and secure the tank according to the load and the installation surface.

• Rated for potable water and compatible non‑flammable liquids
• Maximum contact temperature: 140°F
• Not for gasoline, diesel, or flammable liquids—verify compatibility first

What are the size, weight, and installation considerations?

The tank measures about 36" × 19" × 22" and weighs roughly 25 lb when empty, making it compact enough for many beds, trailers, and equipment platforms. Its square, horizontal shape saves vertical space while providing 50 gallons of capacity. Position the tank on a suitably flat, supported surface, and use correct saddle straps through the molded channels when mounting to a vehicle or trailer.

• Dimensions: ~36 x 19 x 22 inches; empty weight ~25 lb
• Space‑conscious horizontal square profile for versatile placement
• Support on a stable surface and secure with proper straps before transport
