How to Fix Low Water Pressure

Home water pressure problems can come in different ways, but finding it out is a frustrating task. Low water pressure may not give the strong spray that you want and also takes much time to fill a sink or bathtub. Even your dishwasher or washing machine will take much longer to run a cycle than it should. 

Suppose if only one fixture has a problem it can be resolved easily. But if that's not the case, then the whole house will be affected, take the preventive steps immediately.

Is the Low Water Pressure Affecting One or More Fixtures?

If your faucet has low pressure, then check whether other faucets also have the same problem. For instance, if only a particular faucet has a problem with low water pressure then focus and normal in other faucets, focus on the one with low water flow. If the low water flow affects the entire home, then the problem is with the main water supply. Adjust the pressure regulator in your home.

Adjusting the Water Pressure from the Well

Well systems use a pressure tank to supply water throughout the home. Lower water pressure from the well may cause due to ruptured bladder, a broken seal within the pump, or an issue that may be preventing proper pump cycling.

If the water pump fails to cycle when the water pressure is lower than 30 psi, then check the pump's circuit breaker to ensure whether it is tripped. In case the circuit breaker hasn’t tripped, then adjust the cut-out and cut-in points of the switch.

If the pump is running continuously without any increase in the water pressure, then it might be an indication that the tank or pump needs repair or replacement.

Adjusting the Municipal Supply Line Pressure Regulator

Water from municipal supply systems often has a water pressure regulator. The regulator is mostly located after the main water meter.

Adjusting the regulator by yourself can help to check the water pressure to ensure you don’t adjust it excessively. Also, check the pressure by screwing a water pressure gauge in your laundry room or basement and then opening a faucet.

Don't miss to check the pressure reading. If it is less than 40 psi, then open the pressure regulator until the pressure reaches 50 psi.

Flushing Your Water Heater

If the faucets of your water heater have low pressure, then it’s an indication that the tank is blocked. Flush your water heater atleast annually. Failure results in blockages of the water outlet and inlet. You should clean the tank by emptying it and disconnecting all the pipes. Drain the water by closing the inlet and opening the outlet.

Use Vinegar to Clean the Faucets

If the sink faucet has low water flow, then the problem might be with the aerator. Remove the aerator by unscrewing it. Then soak it in vinegar overnight. If there's no improvement then disassemble the entire faucet. While disassembling it, take out the faucet valve and soak it in vinegar overnight. Don't forget to remove any rubber washers and gaskets before soaking the valve.
