Help kitchen faciet leaks from spout into sink

[19 limited wolf pup 16bhs]

Hello, I am new here looking for help with figuring out why my travel trailer (which is a 2019 River Forrest wolf pup limited 16bhs) is leaking water from the faucet into the sink when city water is connected and turned on, after I currently just replaced the water filter that gets connected to hose and trailer outside. Please any on help, I did have the water pump replaced about 3 years ago when I first got this trailer.

Welcome aboard. I would like to suggest a faucet washer might cure your problem but first, Is this the only leak you have? Do you know what pressure your city water is at? Do you have a pressure regulator installed?

Is it dripping or running? If it's two handle it may be a seat washer on one of the stems ( best to replace both), one handle, the cartridge. Your paperwork may tell you what brand you have, which you'd need to know if replacing the cartridge or the o-rings, otherwise, you could take it to a plumbing supply house and they would probably be able to identify the make or "maybe" to a big box hardware. If it's the old two handle type, you can buy a pack of assorted seat washers at any big box.
