If y'all tell me that the Shureflow Accumulator has a check valve in it preventing backflow, then you've solved my problem. I can't find any literature that indicates such though.
Barring that, I cannot figure out why my fresh tank won't fill. There's a lot to take in in the attached picture but basically, water flows to and from the tank through the same pex line with the help of a bypass around the water pump. I installed the Shureflow in place of the old "accumulator" pvc pipe before I realized the plumbing is bidirectional and am thinking that's my issue but don't want to tear it out just to realize something else was the problem.
I can hear water get to this part of the coach when I turn the city water on so it's either the accumulator or the fill valve restricting access to the tank.
No, never heard of an accumulator with check valve. That would kind of defeat the purpose.
X2 what Brett said - yer problem lies elsewhere.
Looking at your photo, I would try this:
1. Close the "Pump Bypass to Fill" valve.
1. Open the "Drain" valve (the upper valve above the water pump in your photo).
2. Run water in from your city water connection.
3. See if water flows straight through and dumps out the drain line.
4. If the water does dump out the drain line, then close the "Drain" valve and open the "Pump Bypass to Fill" valve.
5. If water does not flow into tank, then the "Pump Bypass to Fill" valve is plugged up or broken internally (gate not opening).
Thanks guys. I found an old jammed up static pressure regulator that was the issue. It WAS filling just super super slow. Once I removed that she filled right up.
Well heck-- was about to suggest abandoning the water and just drink wine.
Such an easy fix is still reason to celebrate with some wine. Though I'm learning that easy fixes are not as uncommon as they were with the U320.
Arent you lucky, Mines all under the couch seat and under the front step behind the tank,
Elliot. I wouldn't put that pressure regulator back in the loop, if you were going to. I switched to this type.
That's the one that I still have from my last rig ^.^d
