Hello - brand new to this forum! I'm trying to isolate the filter in order to clean the cartridges. I have the valves on the inlet and outlet ports facing what I believe the be the proper direction to shut off water to the filter, but when I open the drain the water flows out continuously. what am I doing wrong? Attached is a photo of the valves and which direction they are facing. All valves have gate nearest to filter.
Thanks much.
