Great

Expensive, but effective. by Steven Bonebrake

Posted on 9/20/2007 from Danville, PA

Comments: It is an expensive piece of plastic, but it serves its purpose and works great for drains in systems with overflows. By placing this piece on the end of your drain and creating enough back-pressure to drive all of the air out you force your drain to siphon you have a silent overflow and a silent sump. Yes, I would recommend this product to my friends.
