Types Of Horse Trailer Water Tanks

Horse trailer water tanks are necessary for moving horses securely and giving them access to enough water. Water tanks come in an array of varieties, each with unique characteristics and advantages. Here are some of the most common types of horse trailer water tanks you can get for your horse.

Built-In Horse Trailer Water Tanks

Built-in water tanks are built inside the horse trailer’s framework during construction. These tanks provide a better long-term alternative for water supply. Built-in tanks are made expressly to meet the trailer’s architecture and specifications. If you want built-in gravity-fed horse trailer water tanks, then the High Country Plastics Water Caddy is the product for you.

These can be made specifically to the requirements of the caravan. Built-in tanks, as opposed to removable tanks, might have bigger capacity because they are built into the trailer. They have a capacity of at least 100 gallons. Usually, strong materials like aluminum or stainless steel are used to build these tanks, which offer sturdiness and anti-corrosion properties.

Portable Horse Trailer Water Tanks

Portable water tanks are made to be readily removed and replenished. They provide flexibility and adaptability in terms of application and positioning. To match different trailer types, portable tanks are available in a variety of dimensions and designs. They can be anything from little receptacles to bigger tanks with a capacity of at least 25 gallons.

Polyethylene or strong, food-grade plastic is used for its construction. These components are impact-resistant, compact, and water-safe. Portable tanks may be topped off at home or at watering holes, then stowed within the caravan after being filled. To make them simpler to move, they frequently have handles or wheels. Portable horse water tanks are one of the most budget-friendly horse trailer water tank options out there.

Auxillary Horse Trailer Water Tanks

In order to augment the main water supply, extra tanks can be put in the horse trailer. For longer trips or circumstances when a bigger water supply is necessary, these tanks offer additional capacity. They may be installed everywhere around the trailer, including within the storage spaces or beneath the chassis.

Both portable and built-in systems can have additional tanks integrated into them to enhance the overall amount of water storage. Auxiliary tanks can be made to match the required capacity and space constraints during your journey.

Hybrid/Combination Horse Trailer Water Tanks

By blending the benefits of portable and built-in tanks, combination tanks provide users with the best of both worlds. They are made to be adaptive and flexible. Combination tanks can be installed on the trailer or linked to it, making it simple to remove and replenish them.

Combination tanks can give a variety of volume options, from lower sizes to greater capacities, contingent upon the overall layout of the trailer. Combination tanks, like built-in tanks, are frequently constructed of sturdy materials like aluminum or stainless steel to ensure endurance and resistance.
