Works great
I have been using these for years now and they have never let me down. Even when glued in your able to clean the inside if anything gets trapped inside the chamber. Just turn off the return pump, let the water settle and drain water below your overflow intake. Unscrew the top & bottom fittings, clean and reassemble.
