Another problem that been a major issue is "water corrosion" "mineral buildup" (even worse: saltwater corrosion!)
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.
The build quality of this unit is second to none. I was skeptical at first because of the price, but it is totally justified. I like how it can unscrewed and be serviced if needed.
I was skeptical at first- because of the price, but I am so glad I bought this check valve. It makes micro-adjustment of your bubble rate possible. Best check valve I have ever used!!!
I just wanted to let you know how satisfied I am with with your store I have been a customer for over a year now and cant find any reason to shop elsewere your service is awesome and the prices are more than fair Ya sure cant fix whats not broke and thank you for treating me like family. Happy New Year
These boys really know their stuff when it comes to Co2 injection. Do yourself a favor and throw away your check valve and get this one. I did and my bubble count is spot on accurate and never changes!
