Anti-Siphon on Sea Swirl

[favo1984]

Hi There,

I have a 3/4" sea swirl on the end of the my return line from the sump and I was wondering if anyone has experience with drilling the anti-siphon hole in their sea-swirl?

Would it damage the unit at all? The hole has to be drilled into the part that moves so I am a little concerned about damaging the unit.

I was thinking about using a check valve instead as an alternate solution but would prefer to to go with the hole as they can be unreliable and need replacing over time.

Thoughts??

Thanks Guy

Can you post a picture of the return? It would give us a better idea of what you are asking.

I think any picture of a sea swirl wave maker is good enough and better than what I can get picture of. Here is a link to one I found on google.

You really have to be familiar with the sea swirl unit and how it operates or own to be able to answer my question though.
