Water – How to fix the Sputtering faucets in bathroom with air locked in pipes

faucetwater

The hot water faucet is Sputtering heavily. I tried opening up all faucets in the house and let the water run for more than 10 minutes, but the Sputtering continues. This is in the upper level bathroom and only the hot water faucet is Sputtering.

Movement in the hot water supply line below the sink may be touching the shutoff valve thus creating a resonant effect. Try partially closing the hot water shutoff valve to determine if it's modified angle stops the sputtering.

If this stops the sputtering, dampen movement in the hot water supply line or block anything that could touch the shutoff valve when it's completely open.
