Convert CPR Overflow to a Herbie Drain

[@GwonkReefkeeping]

Nice job.
The one that I had came with two drains.
I agree with you that a gate valve makes adjustments to silence the overflow effective.

Thanks. Hope you and yours are having a great holiday.

Risky with just 2. Get a clog in either and you got problems. Need a 3rd as a safety overflow.

How you’d like the smell when drilling it?

Luckily, I'd been drinking, so no effect.
