Air bags on Seneca leak air.

[Sam]

I recently noticed that my 2014 Seneca TS rear air bags deflate after sitting for about one week. When we travel I don't hear the compressor pump running often and the bags are always inflated. Is this normal for them to deflate while sitting for several days? Thanks, Sam

Do they re-inflate when operating? It's not unusual for them to lose pressure over a couple of days, especially with such a heavy load constantly on them. You can use soapy water to find a leak if there is one. I think it's unlikely for the bag to leak on a new coach. If it does have one, it's likely a line or a fitting.

Yes, and will remain inflated for about a week after the unit is parked, usually at home. I have owned the Seneca for seven months and hah not noticed that the bags would deflate over time when parked with out the Jacks down. Thanks for your reply, TWP723.

The bags on our 2014 37TS will do the same after sitting for a few days. Believe it is normal leak-off.

Thanks for the feedback iaccbbieman52. Sam

My freightliner dealer says they should deflate when unit is setting and not moving for a period of time. When moving the rear leveling valves sense movement and hold air in the bag. My bags will deflate within a day or two and always air up upon startup.

Thanks Richard 66 for the information. Sam

Mine does the same thing.

It is good to know that this is normal and something I don't have to be concerned about. Thanks to all who responded. Sam
