Customer Questions & Answers

Question:
What is the purpose of a reverse osmosis water filtration system expansion tank?
Answer: The primary purpose of a reverse osmosis expansion tank is to store purified water. In an RO system, water is filtered and stored under pressure, allowing for quick dispensing. This tank ensures a steady supply of clean drinking water, eliminating the need to wait for ongoing filtration. It’s particularly beneficial for households that consume large quantities of filtered water daily, as having a compact storage solution helps maximize convenience and efficiency. -
Question:
How much water can the 3-gallon RO expansion tank hold?
Answer: The 3-gallon capacity of the RO expansion tank is ideal for residential use, providing enough purified water for cooking, drinking, and other daily needs. This size balances space efficiency and water storage, making it suitable for kitchens of any size. Whether you have a small kitchen or a larger space, this tank will fit comfortably, ensuring you always have fresh water ready when you need it most. -
Question:
What comes included with the RO water filtration system expansion tank?
Answer: Included with the tank is a free 14 ball valve, which plays a crucial role in regulating water flow. The ball valve allows for easy connection to your existing RO system, ensuring efficient operation and allowing for straightforward maintenance. With this addition, you won’t need to purchase any additional components to start enjoying the benefits of purified water through this tank. -
Question:
Is the RO expansion tank suitable for all reverse osmosis systems?
Answer: Yes, this expansion tank is designed to be compatible with most standard reverse osmosis systems. Its universal design means that it can easily integrate into your existing setup, providing you with flexibility in choosing filtration systems. This versatility is helpful for users who may want to upgrade their systems in the future while ensuring they can still utilize their water storage efficiently. -
Question:
How does the pressure in the RO tank impact water flow?
Answer: The pressure in the RO tank directly affects how quickly water is dispensed. A well-maintained pressure level ensures efficient water flow when you open the faucet. If the tank pressure drops too low, the water may dispense slowly or require the RO system to run more frequently to replenish the supply. Regular monitoring and pressure adjustment can maintain optimal flow rates, enhancing usability in daily routines. -
Question:
What maintenance is required for the RO expansion tank?
Answer: Maintenance of the RO expansion tank typically involves checking the pressure periodically and ensuring there are no leaks in the connections. It’s also wise to inspect the tank for signs of wear or corrosion over time. Regular upkeep ensures that the tank operates efficiently and maintains the quality of your stored water, making it a vital part of your overall water filtration system. -
Question:
Can I install the RO expansion tank myself?
Answer: Yes, many users find that installing the RO expansion tank is a manageable DIY task. The tank typically comes with clear instructions and the necessary hardware for installation. You'll need to connect it to your water filtration system using the included valve. While some plumbing knowledge can be helpful, many homeowners can successfully complete the installation, enjoying immediate access to purified water right at home. -
Question:
What are the advantages of a compact design for the RO tank?
Answer: A compact design for the RO tank offers several advantages, primarily space savings and ease of installation. It’s perfect for smaller kitchens or areas where space is limited, as it can fit under sinks or in cabinets without taking up much room. This design also ensures that you don’t compromise on capacity, allowing for ample storage while keeping your kitchen organized. -

tankRo Under-Sink & Countertop Filtration Editorial Review
The tankRO RO Water Filtration System Expansion Tank is a compact reverse osmosis water storage pressure tank which comes in 3 gallons and is ideal for use with reverse osmosis systems. Installation is easy and it does what it claims to. This tank works with a 40psi water system, and it circulates water through post filters before use to avoid any rubber taste in the water. Customers who purchased this tank reported positive experiences but also a few negative ones. One customer reported that the bladder had a slow leak after 4 months of use, while another said the previous tank lasted over 5 years. **
