“I saw another review saying it leaked between the p-trap and the attached tube because it doesn't have a rubber compression washer. Maybe that was an old design, but one of the washers they provide goes on the tip of that tube to seal it.I needed a trap adapter, so appreciated that it was included. Those are an extra $6-$10 to buy by themselves.”
“I installed these in 4 bathroom sinks and it was so nice that the direction of the p-trap is interchangeable. This gave me options for installing in tight quarters. Wish more plumbing pipes had this flexibility. Note: it mounts about 3/16" lower than the standard p-trap.”
“I had a leaky sink p-trap with this same type of click ring, which is strangely hard to find in hardware stores. This kit is inexpensive and easy to install and replace the old one I have in place. Leak was instantly resolved.”
