Maggie mufflers

[NedFlounders]

Was just delivered 2 of these (free of charge thank goodness), installed them...and there is zero difference. If anything, the "slurping" might even be a tad louder. I am going to make a video comparison and try to upload it tomorrow.

Anyone have any luck with these things??

You're running a Herbie drain if I recall from another thread. There is absolutely no need for that. If you're getting slurping from the full siphon you need to cut down the stand pipe if it's too close to the surface and put a gate valve on the full siphon and dial it in. The drain is taking water faster than your pump can send it back. That drain must be adjusted.

The mufflers are designed for durso drains.
