This unit is ideal for bathrooms where a robust flush and long-term durability are priorities, especially in high-use households or commercial-style settings.
PROFLO Jerrit Tank (Less Seat)
The PROFLO PF5112M Jerrit tank offers a tank-only configuration suitable for pairing with a compatible PF1400T bowl. It is crafted from vitreous china and ships without a toilet seat. The design emphasizes straightforward installation for matchups with existing bowls while maintaining a clean, traditional look that fits many bathroom styles. This option is best when you already own the matching bowl or are completing a partial replacement.
PROFLO Calhoun Tank Only – White
The PROFLO PF6112 Calhoun tank is fully backed by ProFlo’s one-year limited warranty and features a vitreous china body for a classic appearance. The tank relies on gravity to flush, providing a dependable option for users seeking a straightforward, no-fruss approach. Like other tank-only variants, seat is not included, allowing you to source a matching bowl separately and tailor the overall depth to your space.
Water-Saving Tank Bank Insert
The Toilet Tank Bank Insert is a water-saving device designed to retrofit older or low-efficiency toilets. This kit claims to save an average of 0.75 gallons per flush, with potential annual savings substantial for households with frequent use. It’s positioned as an affordable, simple solution to improve efficiency without full tank replacement, making it suitable for retrofits where changing the tank would be impractical.
PROFLO Jerrit Tank H.E. (He) – White
The PROFLO PF5112HE Jerrit tank offers a tank-only configuration suitable for pairing with matching bowls. Built from vitreous china, this low-profile tank emphasizes a clean, contemporary aesthetic while preserving compatibility with the Jerrit line. Seat is not included, enabling a customized bowl-and-seat pairing tailored to user preference and toilet depth requirements.
PROFLO Jerrit Tank UHE – White
This tank is another tank-only option within the Jerrit line, designed to accept a matching bowl while delivering a uniform white finish. It is built to support standard gravity flush mechanisms and supports straightforward installation for high-tank setups. Seat is not included, offering flexibility in selecting a preferred seat style and lid design to complete the unit.
Buying Guide: Key Purchase Considerations
- Tank compatibility: Confirm rough-in distance (commonly 12 inches), matching bowl compatibility, and whether you need a tank-only unit or a complete set with seat included or excluded.
- Flush performance: Look for tanks with larger flush valves (3 inches) for stronger flush capability, especially for high-use environments. Consider gravity flush versus pressure-assisted options depending on your needs.
- Material and durability: Vitreous china is common for longevity and ease of cleaning. Check for warranty terms (some brands offer 1-year limited warranties).
- Water efficiency: For retrofit projects, water-saving devices or tanks designed to work with older bowls can reduce consumption. Evaluate potential per-flush savings and annual impact.
- Seat and accessories: Decide whether you need a tank that includes a seat or if you will source a seat separately. Some tanks require you to supply your own matching bowl and seat.
- Installation considerations: If replacing only the tank, ensure your current plumbing is compatible. If you need a full replacement, verify that the chosen bowl/tank combination aligns with your rough-in and mounting hardware.
- Aesthetic fit: Consider the finish (white is standard) and the depth of the tank to maintain the visual proportion of the bathroom fixtures.
When evaluating these options, assess the specific rough-in, compatibility with existing bowls, and whether you prefer a tank-only solution or a broader retrofit that includes a matching toilet bowl. Each listed item offers a distinct balance of compatibility, durability, and potential water savings to address a range of high tank water closet needs.
