Low water pressure can be the result of multiple things. Common causes of low water pressure at a residence is malfunctioning water softeners, pressure reducing valves (PRV), leaking or clogged pipes. To try and determine the cause of low water pressure start by determining if all locations within the home have low water pressure. Check multiple faucets and showers in your home to identify if only certain areas are experiencing the low water pressure. It is also important to check if the low water pressure occurs when only hot or cold water is in use. If the low water pressure only occurs while the hot water is turned on the problem is likely resulting from the water heater. Below you will find more information about common causes of low water pressure:
Water softener: Water softeners can cause low water pressure due to blockages in the system or a malfunction in the recharging cycles. To check if a water softener is causing low water pressure, look for the bypass valve which is normally on top of the water softener. Turn the bypass valve on and check to see if the water pressure has improved. If the water pressure has increased the water softener is causing the low water pressure and may need to be serviced. If low water pressure occurs right after a new water softener was installed. The new water softener may have been improperly installed and you may need to contact the installation company for service.
Pressure Reducing Valve (PRV): A contributor to low water pressure may be the Pressure Reducing Valve (PRV). Shaped like a bell, the PRV is usually located on the main water line where it enters the home. A PRV is a control valve that reduces the input pressure in your plumbing system to a safe level that will not damage your pipes, not all homes have them. When the pressure regulator fails, you will notice the effect on all of the fixtures in the home, and it will happen rather suddenly. Although a pressure regulator can sometimes be replaced by yourself with the same brand and size, in most cases it is better to call a professional to take care of it. Replacing it requires shutting off the water to the home at the water meter shutoff valve.

Leaking or clogged pipes: Leaking or clogged pipes can reduce water pressure by preventing water to flow properly throughout the home. For assistance in determining if there is a leak on a property please call the District at 303.288.2646 to speak to a customer service representative and ask to have the residence checked for a leak.
If low water pressure is still occurring after investigating these common causes please contact the District at 303.288.2646 and have a customer field representative come to the property and perform a pressure check.
