Low Water Pressure

Decreased water pressure usually denotes a plumbing problem. If you're experiencing a decrease in water pressure at your property, the issue is typically within your plumbing system. The list below may help you identify the cause of the low pressure at your property.

Water Softeners

In some cases, the cause of a sudden change or decrease in home water pressure is the result of a water softener.  If it has been a while since your water softener was serviced, you may want to consider having a professional service technician evaluate your water softener’s condition. Depending on the type of water softener and plumbing configuration, you may be able to troubleshoot low-pressure issues caused by your water softener.

One option is to temporarily put the softener in bypass mode to see if pressure increases. If it does, the low pressure is probably caused by the water softener and it may need to be serviced or possibly replaced.

Clogged Aerators

If the low pressure is not affecting every faucet, the problem may just be a clogged or blocked faucet aerator. Check the aerator screens for rust, debris, scale or other particles that may be restricting flow. 

Simply clean or replace the aerator altogether.

Hot Water & Low Pressure

If the low pressure is only affecting the hot water at your property, there could be a problem with your water heater. Check the shut-off valve near the water heater and make sure it is fully open. 

You may need to consult a licensed plumber to evaluate the condition of your water heater and determine if it is affecting your water pressure.

On-Site Water Pressure

Most homes have an on-site water valve located near other on-site fixtures, like a water heater or water softener. The valve may also be located in the garage or on the inlet line between your home and water meter. 

This valve, which may be utilized to make plumbing repairs, allows you to shut off the flow of water to the home. Make certain that this valve is open completely, even the slightest closure can restrict flows and decrease the water pressure.

On-Site Leak

Low pressure also can be caused by a water leak somewhere on the property.
