Rain Harvesting First Flush with Catch-All Tee - First Flush Diverter Kit, Suits 4" Round Pipes

Awesome! It works well in my rain water catching system.

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.

Installed on a customer's rain harvesting system... works great!

Two were delivered but only able to hook up one. The other was missing parts.

keeps some of the junk out of the water tanks

Used this to build a friend a rain irrigation system.

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.

Works well easy install
