I relate this story in case it might help someone else someday.
I decided to de-winterize my trailer today. Got out the hose, put water in the fresh tank, turned on the pump and opened the kitchen hot & cold knobs. Got a brief little drizzle, then nothing. I thought, what the....? Could the pump have gone bad?
So I hooked the hose (with regulator attached) to the screw-on spot so I could get a pressurized water supply. Tried the tap, still no water coming. Tried the tub tap, water flowed freely. Tried the toilet, water comes in there too. Kitchen sink... nada!
I checked the water lines from the inlet to the faucet for kinks. Nothing. No leaks
, either. The line simply T's with part going up to the sink and part going back to the tub, so what could be the problem here? Stood around scratching my head.
Could it be... naw, no way... well, might as well try just to see what happens.... I unscrewed and removed the aerator from the end of the faucet. Turned the cold knob and water sprayed everywhere!
Yep, the aerator had gotten plugged, simple as that.
