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

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

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

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.

keeps some of the junk out of the water tanks

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

Works well easy install

I’m sure I’ll be very happy with this item once I install it

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.

Does not include the plastic tube. Doesn't say this directly, just doesn't have it included in "what's in the box". Something I ignored since it was common sense to me that I would receive what I saw in the photo for the price paid.. That's really shady for something that costs this much. I had to go find one, and the cheapest one I could find was $260 CAD. Do better.

Diverter works OK but was unable to find a clear 4" tube long enough to use in this application. Ended up buying an opaque tube. The kit, for the price, SHOULD come complete as shown...! Only 3 stars for an incomplete kit.

needs to have , 2 inch adapters, running 3 or 4 inch pipe along your house looks terrible
