Water pulsing or having an irregular flow from the
faucet can be caused by various factors. It could be due to a partially blocked or clogged aerator or a malfunctioning valve within the faucet. Other potential causes include issues with water pressure, plumbing system problems, or air trapped in the pipes. If the pulsing persists or worsens, it is advisable to consult a plumber to identify and resolve the underlying issue.
