Re: [A/S] Draining culinary water tank

My 1979 31' center bath has an "overboard drain" so to speak.  A line 
that tees off from the water pump with a valve, and then discharges 
out the bottom of the water tank enclosure.  Whenever winterizing, I 
just let the pump run until that overboard drain is only "spitting" 
water.  Antifreeze is put in thru a 3-way valve that I added, and any 
water that might remain in the tank has not damaged it when 
freezing.  That said, I only completely empty the tank when 
winterizing.

We'll usually head out with a full 50 gallons and come home with 
roughly 1/4 tank or maybe a little less.  That remaining water is 
useful for when cleaning the interior between trips, and is topped 
off before leaving on the next one a few weeks later.

My water tank is centered over the forward axle and I haven't noticed 
any real difference when towing it full or when returning with the 
tank almost empty.

We recently took a trip to the Smokies and I filled the tank about 
1/3 just to have some for emergencies.  The campground we stayed at 
had full hook-ups so I saw no need to haul the extra weight.

One final thing I'll add is that we never drink water from the tank.  
For a weekend trip, several gallon jugs of fresh water from home work 
for anything we consume.
