We took possession of our 2010 3670RL on Dec. 2, 2016. I am a full-timer and have been at a full hook-up campground since then, so I haven't used the 12 volt water system system yet. Today, I noticed water dripping from a small hole in the chloroplast under the basement area, which was very much sagged. I pushed up and that made the water slosh around. I made a larger hole with a screw driver at the lowest point and water began to pour out. The water was not clear, but only slightly cloudy and there was no smell. I thought about doing a taste test - NOT! I turned off the supply water and waited for all the water to drain out of the chloroplast. After letting it drain completely, I began testing by turning on the city supply and then running the sinks and shower, one at a time - no leak from hole in chloroplast during any of these tests. This must be a long term problem, maybe not even noticed by the previous owner, as the chloroplast remained very significantly sagged, even after the water completely drained out of the hole I made. So, here is what I am left with, without taking off the chloroplast:
1. One of my grey tanks is leaking. Does anyone know which sinks, etc. drain into Grey #1 and Grey #2? Do the grey tanks have an overflow at the top of the tank? I am of the school of leaving the grey tanks closed, so that I get a strong flow after draining the black to clean the sewer hose. My old 99 Sunnybrooke had a top overflow on the grey and it would overflow from the top once it got full.
2. Fresh water holding tank leaking or supply to holding tank leaking.
3. 12 volt water pump system leaking.
4. Leak in washer/dryer water system - supply or drainage.
5. Leak from black tank Sani-Flush city water supply plumbing.
6. As mentioned earlier in thread, it could be rain water as we did have significant rain over the Christmas weekend in Parker.
Regardless, none of the above is an emergency. I guess that I will have to take the chloroplast off to know for sure. I have the right tools and know how to do this. I already bought some extra self-tapping screws and washers. Any advice is appreciated. Does anyone know if there is fiberglass batt insulation above the chloroplast? Has anyone else experienced this problem?
Thanks, Mase
