Now, if I can just find a gas manifold that does not have a leaky shutoff valve, I will be golden. The first manifold that I installed did not leak, but it had a faulty check valve that resulted in back flow when I connected a pressurized keg that was filled to slightly above the gas line tube to the distribution system when it was not pressurized. I have since purchased two manifolds that have had leaky valves. I test all of my gas fittings with soapy water.
