There is low water pressure throughout the house, what should I do?

The following scenarios could be the cause of the low water pressure:

Recently added products like water softeners or filters may reduce water pressure. These items may also affect water pressure if they need to be serviced.
If you have a pressure reducing valve (PRV) installed to protect your plumbing, it may need adjusting. Most PRVs are installed after the water meter and before the water heater. Talk to a plumber before adjusting it.
Your main water valve may not be completely open.
If you live in an apartment or condominium or have a business that shares a water meter with others, your neighbors may have increased their water use resulting in an overall decrease in pressure.
If your water pressure suddenly drops to almost nothing it is could be a result of a broken water line. Call 931-645-7400 to report sudden drops in pressure.
