Another wrinkle in the MH Saga... Prepping for the first outing this year (I know, I know, go more often), we attached a hose to the water supply at home to partially fill the water tank... no flow. A groan and a "now what"? Something was definitely amiss. Thinking there must be a blockage somewhere, we proceeded to remove the panel cover above the fill/normal valves and hose connection stuff. An hour later, finally the panel is off and we can see all the poly connections and hoses. Nothing obvious but now starting to trace where the water pressure was being blocked, we decided that it must be something right at the hose connection. After removing a hose splitter/adapter we could see into the hose bib connection and noticed some sort of spring/check valve feature that did not "look right". So we took that apart and suddenly, after re-attaching the hose, we had flowing water again. I guess this check valve had failed in the "closed" position... not even sure why there's a valve here???? The lines were still filled with the winterizing fluid so with water pressure we could now clear that pink stuff out and continue. Of course re-installing the panel was a PITA but now the water works again. I guess I'll order a new hose bib "valve", or maybe not, since I'm still not sure why I need it... some kind of back flow prevention I guess although with the splitter there are manual valves anyway. Soooo, if you ever run into a hose flow issue, check the hose bib connection back flow valve... FYI.
