I have a newly installed Leakshield. It was working fine when I installed it yesterday, but this morning it is showing a state of "unprotected." It seems to be pulling and holding good vacuum. What should I be looking at to resolve this?
The loop is a simple one with a single D5 Next pump on an Ultitube 150 (Leakshield is mounted on top of the Ultitube), a Highflow Next, a couple of rads, and a trio of [Aquacomputer] blocks.
