The common problems with Pur water filters include cracking of the faucet adapter and premature wearing out of the o-ring rubber. Other problems include degrading of valve connecting faucet and filters and slow flowing of water.
Cracking of the faucet adapter is caused by the mandatory physical turn required to activate the Pur Water Filter. Degrading of the valve joining faucet and filters results from poor design of the mechanism that leads to opening and closing of the Pur valve. Clogging and crowding of materials around the o-ring rubber also causes the valves to wear out. This exerts pressure on the filters, causing the water filter to leak. Slow flowing of water is caused by blockages and leaks in the filter compartment.
