Re: [VAL] winterizing the water system (1971 LY Safari 23')



Hi Marg,

Let me tell you not to put antifreeze in the potable water tank.  It would
take many gallons of antifreeze as the water remaining in the tank would
dilute and change the freeze point.  Just drain it.

I disconnect the feed line from the tank at the water pump.  Substitute a
hose with a connection that fits the inlet of the pump and put the other end
into the 1 gallon RV antifreeze bottle.  Typically, one gallon is enough to
fill the system.  I allow the system to drain before I start this by open
the bottom drain and then open all the valves.  Close all valves and then
use the pump to fill the system with antifreeze.  Be especially watchful
with the commode and be sure that you get the color change through the
valves.  I never use the water heater and it remains bypassed.  The small
amount of antifreeze in the pump is OK.  Just be sure that the color change
takes place as you open each faucet.  As I mentioned earlier, you might use
only one gallon of antifreeze to winterize the system.

Even if you winterize too early and use the unit before the freeze, you are
protected.  RV antifreeze is cheap and frequently sells for a buck a
gallon - get several at the low price.

If you predrain the system, most of the color change (residual
water/antifreeze) coming out of the faucets will help protect the gate
valves from freezing.  Catch this in the tanks with the gate valves closed.
Be sure enough antifreeze goes into the "P" traps to keep them from
freezing.  I also add Thetford tank treatment as it lubricates and keeps the
gate valves from damaging freeze.  A small amount of water in the water
heater and potable water tank can freeze without damage to the systems.

Just the quick and easy way I do it and my opinions.  Others may have their
pet techniques.
