Does a Whole House Water Filter Reduce Water Pressure?

Now that you know exactly what a water filter system does, and who may need one, you likely have questions over whether it will affect your water pressure? I mean, surely with all the good that a water filter system can do, low water pressure is the least of our worries? Well… not quite!

Low pressure presents a whole other load of issues and can be a hindrance on aspects of the daily life of a household or business.

The truth of the matter is, whole house water filter systems can reduce water pressure. This is especially true of homes that already have particularly low water pressure.

This becomes even more of an issue when numerous appliances are being used at the same time. For example, a typical household may have the laundry in the washing machine, a dishwasher running, someone taking a shower, and someone cooking dinner all at the same time. In a home with good water pressure, there will be no issues, and all activities will go on as normal.

However, you should not let that put you off. Whilst whole house water filters do reduce water pressure, especially in houses that already have this problem, there are things that can be put in place to mitigate it, and even keep it from happening.

It is also worth seeking out other avenues for filtration if you already have low water pressure, as installing a whole house system could make matters worse. In this case, it may be worth just getting a drinking water filter, or water softener tank, depending on your need.
