So, I am getting ready to install. I really wish I had room to cut the elbow after the inline and before the valve and replace with a tee. Then I could use a FNPT adapter there. I just don't think there is enough pipe above that valve to do that.
Other options:
A. In the pipe just before the elbow
B. into the elbow itself
C. Below the valve, but in the tee fitting. Below that is really close to ground level, and I still have not back-filled the pump area with pebbles yet.
Thoughts on the best location?
