Product review (5 stars): Works perfectly, easy to install.
These traps have worked perfectly so far. Our washing machine drains into a mud sink, and I found that the drain was clogging with lint every half dozen or so loads. After cleaning the drain several times, I did some research and found the traps to keep the lint from ever getting to the drain. They were Very easy to install with the included zip ties, and the size allows for months of use before having to replace the trap. The drain has not clogged since and I don't have to worry about the possibility of the sink overflowing while doing the wash. A great purchase.
