Solid system but missing parts
I received this item very quickly however it is missing one somewhat vital part. When I unboxed the item and started accounting for all the parts I found that the flow control valves were not in the box and I was planning on installing this the next day. Fortunately this is a piece I think I can make in my garage.

In case your float ball is missing or damaged
My order was repackaged and missing the float ball. McMaster part number 3748K18 is a perfect replacement. It also really needs an o-ring at the threaded outlet. Maybe that was also missing? Search Amazon for "silicone o ring size 238" and you'll find the right part. 3-1/2" ID, 3-3/4" OD, 1/8" thickness. Packing is weak; seems like nobody received a complete kit. Thus the 4 stars.
