First the OEM flush device on my RV was SELF WINTERIZING. Yup there is a Vacuum breaker mounted ABOVE the tank somewhere in the RV. with no pressure in the line this allows water to drain eitehr
Inlet to breaker, , back out the inlet
Breaker to Black tank.. into the tank.
At this point you are winterized, no need to do anything. PERIOD, and it worked just fine the first year that way
OP here,
How can you tell if your unit has this feature in the black flush line?
This new 5th wheel has so many new features over my old one. I never had a flush line or even a water control panel before. I just do not want to miss anything and cause damage to the unit. I forgot to empty the water filter on my old 5th wheel the first winter and it froze and broke.
I have the Nautilus P1 water system on this 5th wheel and I was planning on the flowing steps:
Empty all holding tanks Fresh, Grey and black
Drain hot water tank.
Set panel to city water
Blow out fresh water line with air compressor set to 40 psi. Open all faucets and low point drains until only air comes out.
Set panel to fill fresh water tank and blow out this line. Open drain on fresh water tank.
Blow out Black flush line. Drain Black tank
Use the winterize function and pump antifreeze until it comes out all faucets, toilet outside shower etc. I do not have a built in fresh water filter on this rig.
Connect outside shower to black tank flush and pump in antifreeze to fill this line.
Pour antifreeze down all drains to fill traps and some into black tank and then some to cover flap in toilet bowl.
I will remove all food items and anything that rodents might be attracted to. Make sure all windows etc. are securely closed shut off propane.
Close up unit remove battery to put on a maintainer at home.
Wait for spring!
If I have missed anything please let me know
Thanks!
Dave
