Product review (1 stars): Purchasing these cheap filters cost me $180 in labor!
Purchasing these cheap filters cost me $180 in labor.  The first one worked fine and then the water stopped.  I replaced the filter and the water still didn't work.  First thing the repairman did was look at the filter and told me to never purchase these again.  He tested the third filter, still didn't work so a new valve was ordered by him and I ordered a new Bosch filter.  He returned a week later with the new valve replacement.  The first thing he did was replace the filter and the water started flowing. He didn't need to replace the valve.
