How Can I Improve My Low Water Pressure?

Summerville, SC, is known for having sediment in its water. As a result, you can have low water pressure. An average person, even without extensive plumbing experience, can take several practical steps to diagnose and improve water pressure in their home. Here’s what you can reasonably do:

1. Clean Clogged Faucet Aerators and Showerheads

Over time, mineral deposits and debris can clog faucet aerators and showerheads, reducing water flow.

Tools Needed: Pliers, an old toothbrush, vinegar

Steps:

1. Unscrew the aerator or showerhead.
2. Soak it in vinegar for a few hours to dissolve mineral buildup.
3. Scrub with an old toothbrush to remove any remaining debris.
4. Rinse and reattach.

2. Check for Leaks

Leaks in your plumbing system can significantly reduce water pressure.

Tools Needed: Flashlight, water meter (optional)

Steps:

1. Inspect visible pipes for signs of leaks or water damage.
2. Check under sinks, around toilets, and near water-using appliances.
3. Use the water meter test: Turn off all water in the home, record the meter reading, wait an hour, and check the reading again. If it changes, you might have a leak.

3. Ensure All Valves Are Fully Open

Partially closed valves can restrict water flow.

Tools Needed: None

Steps:

1. Locate the main shut-off valve (here’s a video to help you out).
2. Ensure the valve is fully open.
3. Check the shut-off valves under sinks and toilets to make sure they are also fully open.

4. Test and Adjust the Pressure Regulator

A faulty pressure regulator can cause low water pressure.

Tools Needed: Pressure gauge, wrench

Steps:

1. Attach a pressure gauge to an outdoor faucet or hose bib.
2. Turn on the faucet and read the gauge. Normal pressure is between 40-60 psi.
3. If the pressure is low, locate the pressure regulator (usually near the main shut-off valve).
4. Adjust the regulator using a wrench, following the manufacturer’s instructions. Turn clockwise to increase pressure and counterclockwise to decrease.

 5. Inspect and Maintain the Water Heater

Sediment buildup in the water heater can reduce hot water pressure.

Tools Needed: Garden hose, bucket, and possibly a screwdriver or wrench

Steps:

1. Turn off the water heater and let it cool.
2. Attach a garden hose to the drain valve and place the other end in a bucket or near a drain.
3. Open the drain valve and let the tank empty.
4. Flush the tank by opening the cold water supply valve for a few minutes.
5. Close the drain valve, remove the hose, and refill the tank by turning on the water supply and power.

 6. Replace Old Shower Heads and Faucets

Older fixtures might not be designed for optimal water pressure.

Tools Needed: New fixtures, wrench, plumber’s tape

Steps:

1. Turn off the water supply to the fixture you’re replacing.
2. Remove the old fixture using a wrench.
3. Apply plumber’s tape to the threads of the new fixture.
4. Install the new fixture by screwing it into place.
5. Turn on the water supply and check for leaks.
