I have one of these check valves from Green Leaf Aquariums, http://greenleafaquariums.com/products/industrial-check-valve.html, I like the construction of the unit, but the weakness is it has push fittings for the 1/4” OD CO2 hose, I noticed today while it was sumbmerged I in water, as I took a co2 rate measurement, that it leaked a little bit. It’s a small leak, but I find it annoying. It leaks out of the push connects.
Doing a reverse image search it looks to be manufactured by https://www.specialtymfg.com/configurator-plastic-check-valve/ they should have had a compression fitting for something that would be operating at a min pressure of 30 psi.
What check valves do you use? Which ones do you find the most reliable?
