Ditto, I learned the hard way, of course. Sch 80 mips into female brass/copper worked fine for me.

Yes, the system works much better with the PVB installed this way. Of course now you can see my solder drip that is upside down, BUT the PVB is definitely at least 12" above the rotors now....

Thanks hoskm01!

And I will change up the metal to metal transitions and male to female threads.

Mike, I do like fish. Well, except on tank cleaning day anyway

Oh, and no worries about backflow from the tanks themselves, none are hard plumbed into a water source. I fill up 44 gallon garbage cans with water to get the temperature right and add the chemicals. Then I pump the water into the tanks.

Thanks again guys!

That assembly should be tested yearly, by a certified BAT. Call your purveyor for qualified techs.

Why? There is no way for a potential cross connection to the potable water supply. He really doesn't even really need the PVB. And yes I am a certified tester.

What's funny is that I recall Wilkins 720s having pretty clear directional arrows on them... and an instruction sheet.
