## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect for round hole sumps
*by R***N on January 6, 2025*

Made sure you check your sump to see if the filter sock holes or oval or round. This is made for round 4' filter sock holes

### ⭐ Will only fit 4"+ hole, not compatible with all Klir Di-4 adapter sizes
*by B***E on January 29, 2022*

Yes, it actually measures 4", so the hole size must be larger. The Klir Di-4 ships with 3 adapters to fit various sump filter hole sizes or shapes, this only fits one. Alternative sizes include the 4.25" adapter and 3.9" adapter, actual size. My Waterbox sump has the smaller size opening of 3.75", so I installed the 3.9" on the Di-4. While it is great the other adapters shipped with the Di-4, this flow-diverting cap will not fit my sump.

### ⭐⭐⭐⭐⭐ Measure sump size before purchasing
*by A***R on May 17, 2024*

While this is the right size for the hole I was looking to plug the overall size is too large to fit into the portion of my sump I was looking to use it on. This is not the manufacturers error but mine. The piece appears to be quality and I'm sure it would do the correct job should I have done the work on my end.
