Hello, again. After everyone's help here, with our pond waterfall water clarity. I thought we finally got it fixed.
However, the gauge on the external pressurized uv filter system, which has stayed around 3.5 psi, and which the manufacturer recommends never to go over 5 psi, has recently been around 9 psi.
We've followed all maintenance instructions, for backwashing, checked the uv chamber for debris, and I still don't know exactly what is the cause for this.
The only thing it might be is the submersible pump that feeds it.
Originally the sub pump was positioned close to a wall with the intake facing the wall at one side of pond, surrounded with the rocks on the bottom.
From what I read on the manufacturer website, it was designed to stand up, but pond isn't deep enough for that.
The pump goes into the same wall, up to uv filter and returns opposite side of pond.
We moved it to have the intake face the center of the pond and all of the intake above the rocks. This immediately made a big difference in water clarity.
Coincidentally, around the same time the pressure increased was noticed but didn't think it was connected.
I am attaching a picture that shows the filter system, which also shows a 3-way valve on the pipe coming from pump intake. It has always been opened all the way, but would closing some help with the pressure?
