John E Davies Posted April 27, 2017 Share Posted April 27, 2017 Reed mentioned in a new thread that he had lost 20% of his water out the vent while on rough roads. This can happen in other RVs but I would expect that a well designed vent system in an Oliver would not let this happen. Have other Oliver owners experienced this? https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/26621948/print/true.cfm http://www.irv2.com/forums/f115/fresh-water-tank-vent-leaking-147144.html#post1417961 I haven't been able to find a pic of the vent design, it is not shown on the plumbing schenatic in the Owners Manual. Does it go straight down after coming out the top of the tank? Does the pipe extend down into the tank, which will cause a siphon to be started when water sloshes? This is an unacceptable situation for me if it is common, since I plan to dry camp often with no water source for refilling a tank. Any ideas on how it could be easily corrected? Besides "do not drive on rough roads." I have read that a significant amount of the capacity is unusable due to the low and flat design, having another five or six gallons slosh out on the drive to a site would make me very mad.... Also, there risk of drawing in outside dust from the vent. Would a solution to this situation be a raised vent pipe with an exterior filter? I would not care if water vented down the outside of the trailer when filling the tank, if it stopped any water loss during travel. Or you could add a selector valve so normal water overflow during filling was through the existing pipe, and you could switch to a high filtered outside air vent for travel. Comments and ideas are welcome. Thanks.
