Neo-Pure 14 Gallon Key Specs

14 Gallon Capacity

This volume allows you to store a substantial amount of treated water. You can fill multiple glasses or cook several meals without waiting for the filtration process to complete. This capacity suits households with moderate to high daily drinking water needs. It ensures consistent availability during peak usage times, reducing the wait time associated with standard under-sink systems.

3/4" MNPT Connection

This specific fitting size connects the tank to your plumbing line. It indicates a larger diameter pipe compared to standard 1/4-inch tubing. You must verify that your existing RO system supports this connection type. It offers a robust seal and higher flow potential. Check your manifold compatibility before purchasing to ensure the physical interface matches your current setup.

Virgin Polypropylene Liner

The inner liner uses high-purity polypropylene material. This construction prevents chemical leaching into your stored water. It ensures the water remains clean and safe for consumption over time. You benefit from a hygienic storage environment that resists degradation. This material choice is standard for premium tanks, distinguishing it from lower-quality alternatives that may use recycled plastics.

23 Inches Height

The tank stands 23 inches tall when installed. You need to measure your under-sink cabinet or pantry space carefully. This vertical profile requires adequate clearance above the tank. It is a compact footprint for its volume, but you must ensure your cabinet door opens freely. Compare this dimension with other tanks to find one that fits your specific storage constraints.

Build Quality and Physical Dimensions

The tank features a virgin polypropylene liner and a high-grade chlorobutyl diaphragm. These materials keep stored water clean and prevent contamination from the tank walls. A sealed brass air valve and an o-ring sealed cap ensure the air chamber remains leak-free. This design helps maintain consistent pressure during use. The unit includes a plastic tank stand for stable placement. You should position the tank on a flat, level surface to support its weight safely.

According to the listing, the tank measures 15 inches in width and length, with a height of 23 inches. It weighs 23 pounds. These dimensions fit under most standard kitchen sinks, though you should verify your available space. The white exterior uses a two-part epoxy primer and a durable polyurethane paint finish. This coating resists chipping and moisture damage in humid under-sink environments. The stainless steel connections are available in 1/4-inch MPT, 3/8-inch JACO valve, or 3/4-inch MPT options. This flexibility allows you to match existing plumbing lines without adapters. The 3/4-inch MNPT size is suitable for high-flow systems that require rapid water replenishment. The design supports drinking water use in homes and light commercial settings. Ensure your installation area accommodates the tank’s footprint and height clearance.

Setup And Everyday Use Guide

Installation begins with selecting the correct water connection for your existing plumbing. This Neo-Pure model ships with a 3/4-inch MNPT fitting. You can also choose a 1/4-inch MPT or a 3/8-inch JACO valve if your system requires different fittings. The unit includes a plastic tank stand to keep the white cylinder stable during setup. The tank measures 15 inches wide, 15 inches deep, and 23 inches tall. It weighs 23 pounds when empty. You must ensure the sealed brass air valve and o-ring sealed cap are secure before connecting pipes. This prevents leaks in the air chamber.

For daily use, the tank stores treated water for immediate access. The virgin polypropylene liner and high-grade chlorobutyl diaphragm maintain water purity. You can draw water from the faucet without waiting for the filtration membrane to produce more. The durable polyurethane paint finish protects the exterior from moisture and wear. This tank is designed to work seamlessly with Amtrol RO-14 systems. It supports drinking water needs for homes and light commercial spaces. The pressurized design ensures consistent flow pressure. You simply open the tap to receive clean water from the stored supply. The two-part epoxy primer adds an extra layer of protection for the steel shell. Regular maintenance involves checking the connections for tightness. The robust construction supports continuous operation without frequent repairs.

Before You Buy This Tank

This tank is a storage vessel, not a filter. It requires a working reverse osmosis membrane system to produce water. You must verify compatibility with your existing setup. The listing notes seamless integration with Amtrol RO-14 systems. If you use a different brand, check the connection type. This model uses a 3/4-inch MNPT fitting. Other sizes exist, including a 1/4-inch MPT option. Ensure your plumbing matches before ordering. The unit weighs 23 pounds and measures 23 inches tall. You need a sturdy stand or shelf to support it. The included plastic stand may suffice for light use. However, heavy commercial use might require reinforced mounting. Routine upkeep involves checking the air pressure valve. A sealed brass valve helps prevent leaks. You should inspect the o-ring cap periodically. This product fits into a broader ecosystem of RO systems. It does not purify water on its own. Pair it with a reliable filtration stage for best results.

Check before you buy

• Confirm your RO system uses a 3/4-inch MNPT connection.
• Check if your current system is compatible with Amtrol RO-14.
• Ensure you have space for a 23-inch tall tank.
• Verify the weight capacity of your installation shelf or stand.
