Since dewinterizing (I do not recall the issue last season) I have found the smell of rotten eggs - hydrogen sulfide - from my gray water tanks. At first it was isolated to my kitchen sink (the previous couple of trips in March and April), but now I am having the same smell from the bathroom sink and shower.
It typically occurs when I run water down the drains. I verified for the sinks (kitchen and bathroom) that there is a goose neck and, when removed, it appears to be full of water. I have drained and flushed the tanks three times on my current trip - a week in Orlando FL - since there are four of us vacationing in our BH 3385RL. I have added enzymatic tank stuff to counter the smell (the bottle says it is primarily for the black tank, but can be used for the gray tank). That has not helped. I am having no issues with the black tank.
The tanks appear to drain fine when I drain and flush them. I have looked down the vents from the roof, but see nothing. My plan when I get home is to drop a plumbing snake down the vent tubes to see if there is anything obstructing the air flow. Do I need to be aware of any check valves or other concerns that could be damaged when I run the snake down, or is it a free drop to the tank bottom?
Last, is there anything more I can do? Since the goose-necks seem to be holding water, I doubt a deeper one replacing what is there will do any different. The lingering smell anytime water goes down the drains is making the trailer untenable. Any/all suggestions are welcome.
Thanks!
