Rubbermaid Commercial Products Stock Tank 100-Gallons

Best for: Large herds in outdoor spaces or ranch operations where a large, durable water container is needed. This stock tank emphasizes rugged construction and long-term reliability. It is designed for long-lasting performance in varied weather and is made in the USA with a robust warranty.
Why selected: The durable rigidcell construction supports heavy use and outdoor exposure. A category-leading 10-year limited warranty adds long-term protection for critical watering tasks. The Tank’s capacity suits bigger groups while remaining manageable for transport and cleaning.
Limitation to consider: A 100-gallon tank requires sufficient space in pastures or kennels and may be heavier to move for cleaning. Ensure the setup includes a stable, level surface.

Best for: Farms that want automatic water level control for plastic or metal troughs. The Trough-O-Matic uses a float valve mechanism to keep water available without daily checks.
Why selected: It offers a reliable flow (up to 245 gallons per hour) within a 20–50 psi range. The high-grade housing provides durable performance and simple installation for efficient watering in pastures or barns.
Limitation to consider: The device relies on proper leveling and mounting. Improper installation can lead to leaks or inconsistent filling, so follow the included setup guidance carefully.

Limitation to consider: As with any float-valve system, accurate alignment is crucial. If not level, water pressure may cause leaks or unstable operation.

Buying Guide: Rubber Water Tanks For Livestock
- Tank capacity vs. herd size: Larger herds benefit from 50–100+ gallon tanks, while smaller operations can start with 20–50 gallons. Choose capacity to minimize refills without overcrowding.
- Material and construction: Structural foam or reinforced rubber tanks offer durability in varying weather. Look for weather-resistant finishes and USA-made options for reliable support.
- Water level automation: Float valves simplify watering, reduce labor, and help prevent overfilling. Ensure compatibility with your tank size and hose fittings.
- Installation considerations: Ensure level ground, appropriate mounting hardware, and compatible hose connections. Proper leveling prevents leaks and uneven water distribution.
- Maintenance and cleaning: Choose tanks with wide mouths and smooth interiors to ease cleaning. Stock-tank cleaners or safe-chemical treatments can help maintain clarity of water.
- Warranty and support: A long warranty indicates confidence in durability. Consider tanks backed by warranties and U.S.-made manufacturing for added assurance.
- Use-cases and versatility: Tanks can double as outdoor pools, wash stations, or freight-friendly containers for other farm needs if space allows.
Frequently Asked Questions
- What size water tank is best for a small farm? For small operations with a few livestock, 20–50 gallon tanks paired with a float valve can suffice, offering easy maintenance and cost efficiency.
- Can I use these tanks indoors or in barns? Yes, many rubber stock tanks are versatile for indoor cleaning, pet washing, or feed areas, but ensure proper drainage and slip resistance where used.
- Do float valves work with all tank materials? Float valves are compatible with most plastic and metal stock tanks, provided the valve fittings match the tank’s threading and hose size.
- Are rubber stock tanks durable in cold weather? Most models are designed for outdoor use and tolerate cold conditions, but check for “freeze protection” features or insulation if temperatures regularly drop below freezing.
- Is a higher-priced tank worth it? Higher upfront cost often corresponds to longer warranties, USA manufacturing, and tougher construction—worth it for busy farms that require reliability and long-term performance.
- How often should water be changed in troughs? Regular cleaning is advised, especially in warm climates; using bacteria-enzyme cleaners can help keep water clearer between changes.
