CarbonDoser® Precision Check Valve "Corrosion Resistant" (4 psi CRP)
No checkvalve that we have used or tested in the past seems to last very long when used with saltwater. (even stainless steel springs/check balls corrode)
This Checkvalve is custom manufactured to our exact specifications.
It is specifically made for us, with a "ball" that won't corrode and a spring material that it more corrosion resistant than stainless steel.(The actual materials used are proprietary)
- 4 lbs crack pressure (any less is not enough to prevent from sticking open)
- Made with a spring that is more corrosion resistant than stainless steel!
- Made with a check ball that is more corrosion resistant than stainless steel!
- Units are not "glued" when manufactured which allows disassembly for cleaning.
- Do not confuse with similar looking cv's. These cost much more to manufacture... there is a difference!
Maintenance: Even though these checkvalves are highly resistant to corrosion, they still need regular cleaning due to mineral deposits that accumulate and cause the checkball to stick partially open.
If the unit sticks open, water (or even worse, saltwater) will backflow in to the regulator causing damage.
How to clean: Unscrew the 2 halves (carefully with 2 pairs of pliers being careful not to crush). As you disassemble the unit, take note of where the pieces go. Soak all of the pieces in CLR to dissolve the mineral deposits. Ensure all pieces are clean then rinse and reassemble.
How to Test: To perform a leak test, simply reverse the checkvalve, set the regulator on 12 lbs, run it in a cup of water (while reversed) and watch for bubbles.

Probably the best 1/4” checkvalve on the market
This is the 2nd replacement I have bought. Seems like every year or two the get clogged up. I’ve taken them apart to clean them but they never seem to work right again once they have clogged. $30 every 18 months isn’t that bad. This hobby isn’t for poor people, it’s for making regular people poor.
