On trip and kitchen sink must have a gremlin in it
We are on a trip to Tetons/Yellowstone and my DW is convinced we have a gremlin in out kitchen sink. 4 parks so far with hookups. We are using a 50psi regulator. First park, full pressure bath and shower (actually every park), but sink has a trickle. I checked the aerator, removed the head completely, still a trickle. Checked for kinks, found nothing. Convinced we needed a new faucet. Park 2, a little more pressure, but still not good. Park 3, no pressure, dripping. I was going to replace the faucet at park 4. But then, park 4, about 75% flow day 1. Day 2, full pressure. Told the DW I fixed it, but really never touched it. (She knew better that's why the gremlin comment). What am I missing?
