Vacuum Breaker/Check Valve replacement question

[Winged_One]

My JR Products Vacuum Breaker/Check Valve for my black tank flush is leaking. JR Product

I can replace with the same from Amazon, but I was wondering if anyone has used the version from San-T-Flush. It is 1/3 the price.
San-T-Flush version

They both seem to use the same arraignment and fittings. I can reach the item in question under my bathroom sink.

Any reason I shouldn't go with the cheaper version?


Oh, and one final note. I have a compressor with adjustable pressure regulator. What pressure should I set to, for blowing out this black flush line in the future?

Thank you for the information on this. 🙂

Yes you can use the San-T-Flush version.

OR you can do away with that piece of junk, leak prone check valve set up......just use a short nipple and connect the 2 lines together then use a simple garden hose check valve. Roughly $4.

Winterizing.....shouldn't need more than 20# air pressure.
That's what I use to blow out by lines.
