I can take very little credit for the plumbing myself. My job was to put the purple PVC primer on the pieces. My husband did the rest!

We just got a replacement gauge from Pentair today and now the filter is showing pressure. We must have just gotten a bum gauge.

PS: We put a clear flexible plastic tube on the pressure release so that we wouldn't spay ourselves and the inside of our future shed. It channels the air and water under the deck. :-)
