Question: what is the overflow height?
Document: The product image is misleading. The picture shows three extensions on the overflow drain, while the product sent to me only has two extensions. If I knew this I would of ordered an extension.
this item works but I had to sand down some parts to get everything to seal properly. Not a huge deal.
the ebb and flow fittings are great for any flood and drain system. use the 1/2 inch fitting to flood and the 3/4 inch to drain. and you'll need 1/2 and 1 inch tubing to fit these to reduce leaks. youtube has great instructional videos on how to use these fittings and construct your first system. no instructions included
i love these kit but they need a third extension. they install easily, never leak for me (knock on wood) and seem to be free of obstructions after many floods
These are awesome fittings for flood and drain/ebb and flow hydroponic systems. I used them for an entire season and had no leaks!
The item was exactly as described. After receiving the item and inspecting it, it was extremely high quality. I am really happy with what I received.
Perfect for the hydroponics systems I am setting up. Was worried they may not have had the washer, but it doers have them, so they seal perfect. Used some on bottoms of some plsatic totes, and the next round is going into some vinyl fence posts I am using next.
Our child used these for a 4-H fair project and the exhibit was a hit! Recommend this for creating any ebb and flow system.
One fitting is 1/2", the other is 3/4", heavy duty plastic, well made units. Nice to have the 2 extensions so you can adjust the water hieght in your flow table. Very happy with the quality of this product.
Nice idea but the plastic barb breaks off. The barb is made too thin and the plastic around the barb is also very thin. You have to use thin light hose as any heavy ones can break it off just pushing the hose on or pulling it off. Too bad as the rest of it is made very strong. I am going to try to tap the bottom end and use nylon hose barbs to repair so I don't have to replace them. I got 4 sets and most of them broke.
Answer: yes
