## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to install, works well.
*by S***P on July 9, 2025*

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

### ⭐⭐⭐⭐ Solid system but missing parts
*by B***N on January 13, 2024*

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.

### ⭐⭐⭐⭐⭐ Very Necessary for Rain Harvesting
*by S***  on July 15, 2025*

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