Customer Question:

How do I fill the Base with sand or gravel?

Matala Answer:

You need to unscrew the diffuser. Unplug the black plug covering the hole.


Customer Question:

Shouldn't this come with a check valve in the hose fitting?

I didn't receive one...

Matala Answer:

Sorry, there is a check valve built into the disc itself. It isn’t accessible, so some customers don’t know it is there.We don’t have numbers on how effective the built in check valve is, but we haven’t had any issues with customers burning up pumps due to water in the tubing.
