Just noticed that when pump is running on lower speeds, I've got some weeping from my closed-valve waterfall. Water continuously runs down the tile, noticeable enough it leaves ripples in the surface water. Doesn't seem to do it over 2500 rpm on the pump, but certainly does at 1700.
Is there an easy fix for this? I've opened and closed valve several times, but it doesn't fix it. We only use waterfall when guests come over, or we need to aerate.
I'm leary that if it continues I will get hardness buildup on the tile line.
Thanks for any suggestions
