Vegas bathroom faucet has air in lines

Our 2016 Vegas has air in the bathroom faucet, but only the bathroom. Kitchen and all other faucets are running fine. It also seems like the water pump is taking a little longer to restore pressure after running water or flushing. Water tank is down to a 1/3 but dont ever remember this happening in the past.

Checked for leaks and loose connections and all seems good. Any ideas on where to focus our trouble shooting skills?

Thats it! Same activity that happens when you first fill the system with water.

This happened at the beginning of this year, but cleared and appeared normal until we hit the road.

the only time I can remember where I was getting air into the lines, it was because the clear plastic threaded cap for the suction side pump strainer had a hairline crack form being over tightened. In fact I discovered this on my very first night after buying the thing new! Anyway, the crack was basically invisible when the cap was loose/off.

What does happen to my shower lines is that it takes a really long time for air to work its way out...say after dewinterizing for example.

Another off the wall suggestion is possibly one of your low point drains has a slow leak? Is the sputtering in BOTH hot and cold, or just one?

One of mine developed a slow drip, so I added pex quarter turn valves under the coach. It would have been a royal pain replacing the little T-handle valves... just too tight of an area to work in... and I didn't want to put the SAME valves back in there and have the same issue a year from now.

I knew it was sucking air somewhere because the pump would randomly cycle every so often. I had sputtering downstream of the low point valves in the bathroom, but the kitchen seemed fine - no sputtering.

The valves fixed it.

So this is happening only when using your pump with onboard water? How does it perform when hooked up to a city water supply not using the pump?

I am going to test with "city water" this weekend. This started happening while camping last weekend on water tank/water pump.

I visually checked most of the piping for leaks with nothing found. What was confusing me was both hot and cold were having the issues. but only in the bathroom...

So hot and cold water sputtering at bathroom tap only, but all other taps in the coach are fine. So the water pump is likely priming OK. Something common to hot and cold lines to the bathroom taps. I donít think you have any slides in your coach......so likely no crushed/flexed water lines feeding that tap only. The only other thought is the tap spout filter may have debris inside that is causing your strange flow for both hot and cold? Just a WAG.
If yes, then city water will also sputter.

Thanks for all the replies and support..

I had checked the actual water lines for leaks and tight fittings, however, until I started reading your replies I hadn't thought of the "anti-freeze fill nozzle" which is also on the fill side of the pump (as you all mentioned).

That was the issue, I hadn't fully tightened the plug on the fill nozzle and apparently, it was sucking air into the pump. Connecting to city water was fine (of course) so that pointed to the pump introducing the air into the system.

Thank you all
