Only lasted a few months before leaking. The drain switch allowed a constant flow of water (including very hot water) to flow through the filter even when it was in the off position. For me the shortest service life of the pur filter. Although this is a known defect of this model. I had to ship it back to them at my own expense to get a replacement. In the past, Pur has done well replacing filter housings, recognizing that the money is in the filters, but no more. Now they want the broken/defective ones to be sent back at the customer's expense. They must cost them a fortune in hazardous materials disposal fees, but they don't significantly reduce replacement orders. Some consultant must have been paid a fortune for a brilliant idea. Would you like fewer returns/replacements, Elena Troyanskaya? Make them better! Your money in filters! Be like Gillette and give away pens (cases)!
