FIXED - low water flow inside coach - both shore and water pump 2003 U320
EDIT - fixed. Read last post for details.  Thanks all!!!!

VERY low water pressure and flow at shower head, kitchen sink, bath sink.

We have wintered in Texas in multiple Thousand Trails parks, with what seems to be hard water.

We always filter all...

Any difference between all hot and all cold water?

There is some info on the forum about the AquaHot coils developing hard water deposits - vinegar being the answer there.

Any dollar stores near you?  They usually have vinegar.

I'll check tomorrow.  I'm sure I can find some somewhere.  I still "think" I will have to do some disassembly to attack deposits directly -...

Added note: I also made sure water fill switch is off and cycled it a couple of times.

If the problem is post-pump, you can use a winterizing hose set-up to suck vinegar into the water lines for all the taps (run each until you smell vinegar.  Thinking it was about 5 gallons to winterize that coach including the Splendide, so 5...

Another thought, albeit a very remote possibility.  If the fill valve seat is not making good contact or if the solenoid is not working properly and not closing the fill valve it could short circuit the water flow.  There is both a solenoid on...

Since the low flow is at every tap, hot and cold, on-board water or city, the restriction should most likely be from the Tee where the pump discharge and tank fill valve meet, and the Tee where that supply line splits to the Cold side of the...

I've been outside until I just lost light (and it just started raining). I was tracing water lines and checking what is what.  And I also "suspect" the same valve Michelle pictured.  (I even just took photos a few minutes ago to ask about when I...

Just a thought, possibly the fill valve has a little bit if trash in it causing it not to close completely when off.

Pics of where I was checking.  I did unscrew 2 connections on the water manifold - no buildup at all.  And I have cycled the water fill switch inside the coach a couple of times.


Now raining hard and some hail so no go tonight (at least right away)

That's what I thought as well - and why I screwed it down and...
