Blew out water lines. Hooked up, no water @ bathroom faucet

[LARRYSLC]

Hello. I blew out my water lines on my:
2012 Fuzion FZ375 before leaving for Christmas with the family. 2 weeks later, returned, hooked up the water and now have no water at the bathroom faucet. Kitchen, toilet, and shower all work fine.
Any ideas?
Thanks in advance- Larry

Thank you both. I was going to "back blow" the faucet, and when I got the aerator off, there was the culprit-calcium! Thanks again-

Another device many do not even know is there...

In the Kitchen I have one of the "Pull out" faucets.. This type has a back-flow preventer in the handle.. I've seen them clog.

That aerator will get you every time. 9/10 it is the simplest thing.

Water works everywhere else is usually a pretty good indicator of a plugged aerator screen. Blowing the lines out can loosen up a fair amount of mineral scale, so check them all when you get to it.

Is your fresh water tank overflowing? Not joking, Many Rv's have a "Quick Fill Valve" these work one of two ways.. Both the same if properly operated

IN the proper operation you set it one way it fills the Fresh Tank, the other way it passes water to the RV... But what happens if you set it half way in between (This is where they split)

Mine, allows the water pump to "Recurculate" water back to teh fresh tank, Both sides are "half open" city water will also divide and overflow the fresh tank as well as low pressure to the house.

Some, I suspect, may not pass water at all if set to the "Mid point"

ALso as others have suggsted check any screens (inlet washer screen) filters, make sure the City Water is ON. and so on and so forth.

make sure the levers setting the "normal" use positions are set there...I am alway filling my tank and forgetting to return to city water use...

Just had the same issue, but had flow earlier removed the screen and had lots of flow. Then cleaned screen!

ND, been darn cold there so I would bet Roy's frozen line idea is the problem.

Exactly......

No cold or hot then aerator on end of faucet is clogged

Have you tried using the water pump? If your plumbing works when using the on board water then you can focus on the exterior water supply and check valve located where you hook up your exterior water.

This is a very basic water flow diagram for the RV. Getting water at some locations and not the other is very strange. Hope you didn't rupture a water line somewhere when blowing out the lines with high pressure air... Perhaps your bathroom line is frozen... Use an hair dryer with caution on the line here perhaps...

I blow my lines out with a very low pressure output using a tankless 12VDC portable air compressor. I used an air adapter at the city water input port.

I am able to walk around to all of my faucets and open each one at a time to drain out the water and eventually get air only coming through the lines. The air pressure probably never got higher that 20 lbs or so...

I would open some cabinet doors and following the water lines looking for a water leak...
