CMP 27051-019-000 Blue & White Floating Spa Chlorinator
The CMP 27051-019-000 is a blue and white floating chlorinator and brominator designed for spas, hot tubs, and other small-water-volume applications using 1-inch sanitizer tablets. Its adjustable dispensing control gives you a simple way to manage tablet dissolution without plumbing, wiring, or a permanently installed feeder.
ATB Compatibility Note
This is a functional replacement for the discontinued Pentair R171090 floating feeder. It is intended for the same general spa and small-pool use case, including adjustable dispensing of compatible 1-inch sanitizer tablets.
It is not an inline chlorinator, an automatic salt system, or a plumbing-connected feeder. It floats directly in the water and should not be used with 3-inch tablets.
Why Choose the CMP 27051-019-000?
Small bodies of water such as spas and hot tubs can use sanitizer quickly, especially with warm water, heavy use, or frequent cover removal. A floating dispenser helps provide a more controlled, gradual tablet feed between water tests and routine maintenance.
- Current replacement option for the discontinued Pentair R171090
- Top-load design makes tablet refills simple
- Adjustable dispensing control helps tailor sanitizer release
- Blue and white floating design is easy to spot in the water
- No plumbing modifications, electrical work, or hard installation
- Useful for compatible spas, hot tubs, splash pools, and small pools

CMP 27051-019-000 vs. Pentair R171090
The original Pentair R171090 was a beige-and-white Rainbow #335 floating spa dispenser for 1-inch chlorine or bromine tablets. CMP 27051-019-000 serves the same general purpose in a current blue-and-white configuration.

Compatibility & Important Use Notes
This dispenser is a good fit when:
- You are replacing a discontinued Pentair R171090 or Rainbow #335 dispenser.
- Your spa or small pool uses 1-inch chlorine or bromine tablets.
- You want a simple floating feeder instead of an inline or plumbing-connected system.
- You need an adjustable tablet-dissolution rate.
Please keep in mind:
- Do not use with 3-inch tablets.
- Do not mix chlorine and bromine products inside the dispenser.
- Do not allow the dispenser to remain trapped against vinyl, acrylic, painted, or other sensitive surfaces.
- Always test sanitizer levels regularly and adjust the dispenser setting based on your actual water chemistry.
- Use only as directed by your chemical manufacturer and pool or spa equipment manufacturer.
How to Use the Floating Dispenser
- Open the top cap of the dispenser.
- Add compatible 1-inch chlorine or bromine tablets.
- Close the cap securely.
- Set the adjustable dispensing opening to a conservative starting position.
- Place the dispenser in the water and allow it to float freely.
- Test sanitizer levels routinely and adjust the setting as needed.
Start low and increase the opening gradually if your sanitizer demand requires it. Water temperature, sunlight, swimmer load, spa cover use, and water volume all affect how quickly sanitizer is consumed.
