Where the RO Re-Pressurization Fits in Your Water Line
The RO Re-Pressurization System is installed after the reverse osmosis treatment equipment. Treated water produced by the RO system is collected in the storage tank, then re-pressurized by the booster pump before being supplied to the home or application.
The exact layout may vary depending on the RO equipment, additional water treatment, and system configuration.
Diagram highlights pre- and post-filtration recommendations for a complete setup.
Installation Note: For best performance and to help prevent rapid pump cycling, install a bladder tank on the discharge side of the pump. DAB recommends sizing the bladder tank based on your pump’s normal peak flow:
- 2-gallon bladder tank – E.SYBOX Mini 3 (approximately 10 GPM)
- 4-gallon bladder tank – E.SYBOX, DTRON 2, and DIVER (approximately 20 GPM)
- 10-gallon bladder tank – E.SYBOX MAX (approximately 50 GPM)
How the Storage Tank Refills
Water produced by the reverse osmosis system flows into the RO Re-Pressurization storage tank. A float inside the tank communicates with the RO system to control water production as the tank fills and empties.
An electronic tank level control may also be available as a custom option for applications requiring a different control configuration.
Have Existing Water Treatment?
Water softeners, iron filters, UV systems, and other treatment equipment can be incorporated into a Well Watcher™ installation. Placement may vary depending on the type of treatment and your existing water system.
If you’re unsure where your existing equipment should be located, contact our team for help reviewing your installation layout.

Your Pump Configuration Can Affect System Space
The amount of installation space required can vary depending on the booster pump selected and whether the pump is installed internally, externally, wall-mounted, or alongside the system.
Review your specific system configuration when planning the installation area, and allow adequate space for plumbing connections and future access to the pump and system components.
Planning a Multi-Tank System?
Additional storage tanks can be added to increase available water storage. Because multi-tank systems can be arranged differently depending on tank orientation, pump configuration, and available space, overall dimensions will vary by installation.
Contact our team if you need help determining the footprint or layout of your specific configuration.
Plan for the Weight of a Filled System
A filled RO Re-Pressurization™ 210 tank can exceed 1,800 lbs. The system must be installed on a level concrete slab or a properly reinforced wood or steel subfloor capable of supporting the filled system.
Condensation should also be considered when selecting the installation location. A condensation pan and access to a nearby floor drain or sump area are strongly recommended.
Built for Water Storage
RO Re-Pressurization Systems use durable polyethylene tanks designed for potable water storage. Their ribbed construction provides added strength, with multiple tank orientations available to accommodate different installation spaces.
Explore our water storage tanks for more information about tank construction, dimensions, orientations, and features.
Simple Plumbing Connections
RO Re-Pressurization Systems arrive pre-assembled with much of the system plumbing already in place. For a typical installation, your installer will connect the incoming well line to the system and connect the system outlet back into the home’s main water line.
Standard RO Re-Pressurization Connections
- Inlet: 1/2″
- Outlet: 1″
A 3/4″ and 1″ inlet are available by custom order. Installers can also use appropriate reducers or adapters as needed to connect the system to existing household plumbing.
The piping between the storage tank and booster pump is typically provided by Well Manager based on the selected system and pump configuration. If the booster pump will be mounted away from the system, additional on-site plumbing may be required.

Filtration & Expansion Tank
Plan for the required pre-filtration and expansion tank when completing your RO Re-Pressurization plumbing connections. Refer to the system layout and pump information above for placement and sizing details.
Plan for Overfill Drainage
The RO Re-Pressurization includes an overfill safety connection near the top of the tank as a backup in the event of an unexpected overfill. This connection must be routed to an appropriate drainage location, such as a floor drain, sump basin, standpipe, or other approved drainage area.
Plan for drainage when selecting your system location. Flexible tubing or PVC can be used to safely direct overflow away from the system and surrounding floor area.
RO System Connection
A float inside the RO Re-Pressurization storage tank connects to the reverse osmosis system to control water production based on the tank’s water level. As stored water is used, the float signals the RO system to produce additional treated water and refill the tank.
Need a Different Plumbing Configuration?
The RO Re-Pressurization is built with a standard 1″ inlet and 1″ outlet. A 3/4″ or 1″ inlet can be requested as a custom option, and installers may use reducers or adapters where needed to connect the system to existing plumbing.
If your project requires a different pump location, piping arrangement, or a custom commercial configuration, let our team know before your system is built.
