Easy Installation and Compact Design
Design & Build Quality
This tankRo RO expansion tank impresses with well-thought-out construction. The use of 100% food-grade materials means your drinking water stays clean and free of contact with harmful substances. The body is made of deep-drawn steel domes with precision welding along the seams, giving it a rugged feel that should resist dents and corrosion over time. One customer noted, “The tank looks sturdy and the ball valve fits perfectly, making installation painless.”
The compact shape maximizes under-sink fitting space without compromising internal water volume. It holds enough filtered water to reduce the usual wait associated with RO systems. Additionally, the tank ball valve included makes connections quick and secure, even for those with minimal plumbing knowledge. This feature often saves costly plumber visits.
Another appreciated design element is the pre-pressurized air bladder inside the tank. It maintains consistent water pressure, so faucet flow remains strong even at peak usage times. The overall finish also suggests this tankRo product underwent rigorous quality control checks.
Real-World Performance
In daily use, the tankRo RO expansion tank provides consistently smooth water flow. Users who replaced older tanks reported a significant improvement in how quickly water fills their glass or pot. One reviewer shared their experience: “After installing this tank, I no longer have to wait several minutes for my water to come out at a decent rate. The pressure is steady and reliable.”
Thanks to the included ball valve, you can turn off water supply easily during maintenance or tank swaps, reducing mess and hassle. The tank’s design effectively prevents leaks and holds pressure well, ensuring longevity and peace of mind.
This storage tank performs well enough to meet the needs of both small families and moderate water users. However, very large households using multiple faucets simultaneously might find the 3-gallon capacity moderate but still adequate for everyday needs.
Reliable Pressure and Fast Flow
What Makes It Stand Out?
Compared to other RO expansion tanks, the tankRo unit strikes a fine balance between compactness and capacity. For example, competitors like the Express Water 4 Gallon Expansion Tank offer slightly larger storage but tend to have bulkier profiles that can crowd under-sink spaces. On the other hand, the Watts Premier tank sometimes requires extra fittings for installation, whereas tankRo includes the ball valve as a standard.
The tankRo tank’s durable steel construction also stands out versus plastic or composite tanks prone to cracking or corrosion. Many users praise tankRo for lasting well beyond one year without pressure losses or deterioration.
Its pre-attached quick-connect valve is a nice touch that equips both DIYers and professional plumbers to install or replace tanks without fuss quickly. This approach reduces downtime and mess associated with many RO tank changes.
While it doesn’t hold the largest volume in the RO tank market, its combination of ease-of-use, quality materials, and reliable performance makes it a strong candidate for most household needs.
