Fix Low Water Pressure from a New Kitchen Faucet in 6 Easy Steps
Installing a gleaming new kitchen faucet should be an exciting home upgrade. But your anticipation can quickly turn to frustration when that fancy new faucet sputters and splashes out a weak trickle of water.
Before you despair, don't give up on your new faucet just yet! In most cases, low water pressure issues can be resolved with some simple troubleshooting. Follow these 6 easy DIY steps to get your new kitchen faucet flowing at full pressure again.
Check for Clogged Aerator
The first place to check is the faucet aerator. This small screen on the tip of the faucet spout regulates water flow. Over time, mineral deposits and sediment can collect in the aerator and restrict water flow.
To fix this, unscrew the aerator counterclockwise and rinse it under warm water to remove any trapped particles. Be careful not to damage the delicate aerator screen. Once clear of debris, reattach the aerator by screwing it back onto the faucet spout.
Inspect the Cartridge
The next likely cause of reduced water pressure is a problem with the faucet cartridge. This inner valve controls hot and cold water flow through the faucet. A faulty or misaligned cartridge can inhibit proper water flow.
To replace the cartridge, first locate it inside the faucet body and identify the correct replacement part number. Turn off water supply lines before removing the old cartridge. Follow the manufacturer instructions to install the new replacement cartridge. Be sure it is properly aligned and secured.
Check Supply Valves
If the aerator and cartridge check out, take a look under your sink. Partially closed supply valves can limit water flow to the new faucet. The shut-off valves on the hot and cold water lines regulate flow from the supply lines.
Make sure both valves are turned completely counterclockwise to the open position. This ensures full water pressure is coming through the supply lines unobstructed.
Examine Supply Lines for Clogs
Sediment buildup in the supply lines themselves can also impede water flow. To check for clogs, disconnect the supply lines from the faucet connections. Turn on the water to see if flow is strong and steady.
If flow seems obstructed, try clearing the lines with a wire brush or vinegar solution. For severely clogged lines, replacement may be necessary. Connect new supply lines of at least 1/2 inch diameter for optimal water flow.
Inspect Supply Hoses
Be sure to check that the flexible supply hoses are not causing the low pressure issue. Kinks or tight bends in the hoses can restrict water flow. Examine the hoses for any crimps or obstructions.
Carefully straighten any kinked hoses. Replace cracked or swollen hoses. Keeping the supply hoses smooth without tight bends maintains continuous water flow.
Finally, improperly installed faucets can fail to achieve full water pressure. Check that your new faucet is firmly seated on the sink with the gasket in place to prevent leaks.
Confirm all supply line connections are tight with no drips or seepage. Electronic faucets with separate power supply should be correctly hooked up. Proper initial installation optimizes water flow performance.
Following these 6 troubleshooting tips should solve low water pressure problems with a new kitchen faucet. Before replacing the faucet, try these simple repairs to restore full water flow and enjoy your upgraded fixture.
With good maintenance and occasional aerator cleaning, your new faucet will continue providing optimal water pressure for years of service at the kitchen sink.
