Hi all, brief update. I did the flush again (because, yeah, the first time I did it, I left the grey valve open and the shower valve closed.) So I flushed with them open, then flushed with them closed, adding odorloss to the sink. It helps somewhat but the distinct pew odor is still there. I really am not quite sure where it's coming from, but if I open the toilet, it smells fine. But I haven't exactly stuck my nose right on the shower drain.
Also, when I run the sink water, at first, it smells a little moldy coming out of the tap. So something in there is not clean--it could even be the shower hose itself. Maybe I need a new shower hose. Or maybe it's the plastic piping under the sink.
I did go to Lowes and get a new p trap (a green rubber thing) and two clamps. The guy who can change it for me for a few bucks, was working today from noon to eight, and I didn't get there in time. I got a little cute microfiber rug for the entrance, various cleaning and waxing stuff at autozone. DH did the whole exterior with soap and water but didn't have time to wax--does that mean we have to soap and rinse lightly again before waxing? It looks nice and clean now.
I didn't get a chance to clean more on the inside either (we'd cleaned the bathroom and all the surfaces of the wood/fiberglass, but not the interior sides of the surfaces, nor the fridge
interior. We also haven't vacuumed, nor steam cleaned etc.
So anyway I hope we can get back tomorrow to get the p trap done in the morning.
Clearly there's SOMETHING in the grey or black tank or piping, probably the grey tank/piping. It smells bacterial.
Eddie recommends the hepvo mod (I need to order by email--little customs wrote me back)--the dometic ceramic toilet and maybe cleaning and even waxing the bathroom fiberglass if it absorbed the odor but it seems okay from a sniff. Who knows.
1) To clean the grey tank with the tank wand--is there some opening I can stick it through, the way Carol does with her scamp
? All I have is the valve i open and close but that has a handle. I don't want to damage anything.
2) Someone at the campground told me I must always have some water in my black and grey tanks especially in the hot summers here. And I now understand a p trap must have water to keep back the odors. That seems such a hassle to remember (use the grey tank, and periodically dump it--I doubt I will be using the black tank much unless it's middle of the night kind of thing)--I definitely want the hepvo valve. I guess I can't just use the sewer hookups at campgrounds except for periodic dumping of grey and black tanks. I'm new to trailers and this is kind of bothersome to me--that I can't have empty tanks ever, without potentially causing them to crack?--and that without the hepvo mod I am vulnerable to odors from a dry p-trap. Moreover, I agree with everybody, sheesh, every time you want a shower, go out and sit down and pull the valve out near the tongue, and then every time you're done, go out and push it back? So a hepvo mod seems essential.
So I will report back if I still have odor after a new p-trap (or see if the old one has gunk.) Ziggy recommended leaving the tsp or odorloss in a full grey tank overnight...I haven't done that yet.
