Yes, a water filtration system for the home can reduce water pressure since it acts as a restriction point for water flow before it enters your home. The good news is that if you install the correctly sized unit for your home, you won’t notice the tiny two to three psi drop in water pressure.
The most common cause of low water pressure is using an undersized filtration unit. These units have a lower flow rate, which means that the unit will struggle to keep up with your household demands, leading to a general drop in water pressure. Searching “water filtration companies near me” is the first step to finding out what your ideal unit should be.
Clogged or dirty water filters can also reduce water pressure since water has to work harder to move through the clogged filter. Luckily, replacing the filter will restore water pressure to its normal psi.
