Check Valve Over-Kill?
- I've filled quite a few tanks since I rebuilt the Back Pressure Regulator (aka PMV) and have some observations and questions.
- First, you can see by the photo below that I installed the air outlet on the top and an additional drain/bleed valve on the bottom. The hose from the air outlet goes up about 3 feet vertically to my filter array. And my filter array has a check valve/PMV that keeps the filter array at or above 1500 psi to squeeze water out of the air. So the entire length of the hose from BPR to filter array acts as a moisture condensing tower with a drain at the bottom. ().
- This is essentially a second moisture condensing system. The RIX has two moisture condensing towers of its own that are positioned before the BPR in the air flow. Surprisingly, there still is some moisture in the air as it passes beyond the BPR. So, that drain at the bottom does let out some water even though a bunch was squeezed out by the two primary moisture condensing towers.
- But I am almost never seeing any moisture coming from the condenser on the filter array... So, I thinking I'm getting the moisture out.
- My question is whether the extra check valve that's installed just before the BPR might be affecting the efficiency of the BPR in a negative way? The RIX manual and diagrams indicate that the BPR serves as a check valve. They don't show any additional check valve before the BPR. I'm wondering if the check valve might be compromising the seal of the BPR, allowing moisture to make it though?
