Cary,
See attached for video of our hall pump problem. It would cycle on and off every 60sec or less, water hammer, and dim the lights. Notice even the old blue valve that never worked and was leaking.
I will send the "After" fix next.
You sell a wonderful product and have good technical support and know how.
THANKS FOR YOUR HELP.
Clay
