Installation was straightforward as usual. However, frequent leaking and stalling started to occur after a few hours. Part of it was not visible and led to damage to the floor after three weeks. The filter encasement is fine. The main reason for the leak seems to be the two o-rings where the filter connects to the water line. The o-rings are clearly thinner than those of the original PUR filters (I was able to compare with an old one). I replaced the o-rings with the thicker ones and the filter worked well for nearly three months. Then, it started to leak and stall again, requiring frequent removal and reinstallation. I expected much better quality from Walmart.
