Duotight gas manifold build

[quantumguy]

I'm replacing the gas manifold in my small 2-keg keezer (actually a converged fridge) with a duotight manifold with the mini inline regulators from Kegland. I'm planning to install duotight ball valves in order to isolate each keg if need be. Is there any advantage to placing these ball valves on the input sides of the regulators or the output sides? I've seen pictures online for both configurations.

What did you end up doing?

I put my ball valves after the manifolds on the keg side, but now i think i'm going to switch them around. I'd like to know that the tanks are holding pressure when the valves are off.

...and maybe I have a gas leak somewhere because i didnt spray test when i was done...too thirsty! so i have to redo all the fittings and test this time anyway.

I ended up putting them on after the regulators on the keg side. I liked the idea of protecting the regulators from anything coming from the kegs (even though I have check valves in the gas-in QDs). It would be nice though to have them before as well for leak testing. Maybe do both but that seems like overkill. For just leak testing my kegs, I bought a Kegland duotight digital pressure gauge that I can just pop onto the gas QD.
