Only the kitchen faucet, all other in trailer work fine, will start with full pressure, lose the pressure, and if I turn the water off then back on, it sputters so hard that it can be felt on the counter. This only happens with hot water, cold runs fine. There is no leak under the trailer, and the aerator is not removable. What could be the problem and how can I fix it?
The washer in your kitchen faucet's hot water tap is loose or worn, and is flopping around when the tap is opened. Replace the washer and you should be fine.
