Separation of potable and waste water systems
Yahoo Message Number: 110062
I was just reading on an SOB websit about the fact that some motorhome manufacturers put the potable, grey and black water tanks in the same bay. My previous rig had the potable water tank under a sofa just aft of the driver's seat and the waste tamnks were together in a bay aft of the rear axle.
 How does LD arrange these items? For me, it would be a deal-breaker if potable water was anywhere near the waste tanks.

Frank,
 I believe all recent LDs have the fresh water tank above the floor level somewhere inside the rig.  None of the fresh water plumbing is below the floor.  The holding tanks on the other hand are suspended from the truck frame below the floor level.  The positioning of tanks depends on the floor plan and the need to balance the weight of rig components.

Frank,

I think it's safe to say all LD's have the fresh water tank above floor level and the waste tanks below.  My '91 MB has the fresh tank a few feet behind the drivers seat and resting at floor level.  The gray tank sits behind the rear axle, below floor level.  The black tank sits below floor level ahead of the rear axle.

Hope that helps,

-Victor

Frank, look under any home's bathroom or kitchen sink, and you'll find fresh water pipes and sewer lines not only in the same compartment, but just inches apart. Yet I doubt you lie awake at night worrying about the possibility of a water pipe and a drain line both simultaneously springing a leak, and thus contaminating the water from your faucet. Well, the chances of that happening are a lot greater than the chances of both a freshwater tank and a black tank simultaneously leaking and cross-contaminating the fresh water. It just isn't something to worry about. :-)

Thanks for the feedback, folks. One more negative is now put to rest.
 IMO, there's a big difference in the risk of cross-contamination in an RV compared to a house system. In a house, the toilet plumbing doesn't go close to either the grey or potable lines and the potable water supply lines are pressurised all the time.
