How to winterize your recreational vehicle that includes an ice maker and/or a washing machine
1- DRAIN FRESH WATER TANK.
2- OPEN LOW POINT DRAINS.
3- TURN OFF ELECTRIC WATER HEATER SWITCH.
4- DRAIN WATER HEATER
5- HOOK UP AIR TO CITY WATER INLET. BLOW ALL WATER OUT OF WATER HEATER AND LOW POINTS.
6- CLOSE WATER HEATER AND LOW POINTS DRAINS. OPEN ALL FAUCETS WHILE UNDER PRESSURE TO BLOW ALL WATER OUT OF FAUCETS, TUB/SHOWER, TOILET & OUTSIDE SHOWER.
7- IF YOU HAVE A FILTER UNDER YOUR SINK OR ELSEWHERE, YOU WANT TO REMOVE IT & INSTALL YOUR FILTER BYPASS BECAUSE ANTIFREEZE WILL RUIN IT. IF YOU PLAN ON REPLACING IT NEXT YEAR, JUST LEAVE IT IN PLACE.
8- FIND WATER PUMP & UNHOOK SUCTION SIDE OF PUMP. INSTALL A HOSE WITH FITTING ONTO PUMP & INSERT INTO A JUG OF ANITFREEZE.
9- TURN BYPASS VALVE ON THE WATER HEATER TO THE BYPASS POSITION.
10- IF NOT BYPASS, YOU HAVE 2 OPTIONS:
A) FILL WATER HEATER (REQUIRES AN ADDITIONAL 6 GALLONS) OR UNHOOK LINES FROM REAR & INSTALL A FITTING BETWEEN LINES TO MANUALLY BYPASS, OR
B) TURN ON PUMP & RUN ANTIFREEZE THROUGH ALL FAUCETS, TUB/SHOWER, TOILET, AND OUTSIDE SHOWER- BOTH HOT AND COLD. THIS SHOULD TAKE APPROXIMATELY 1 1/2 GALLONS.
11- IF YOU HAVE AN ICE MAKER, YOU WILL HAVE TO CYCLE THRU THE ICE MAKER TO GET ANTIFREEZE THRU THE LINES & INTO THE ICE MAKER.
12- IF YOU HAVE A WASHING MACHINE, YOU WILL NEED TO SET TO WARM TO PUMP ANTIFREEZE THRU BOTH HOT & COLD SIDES. THEN PUT ON SPIN CYCLE SO IT WINTERIZES THE PUMP IN THE WASHER.
13- TURN BYPASS VALVE BACK TO NORMAL POSITION OR RECONNECT THE LINES ON THE WATER HEATER & PUMP REMAINING 1/2 GALLON OF ANTIFREEZE INTO WATER HEATER.
14- UNHOOK PUMP & REINSTALL HOSE TO TANK.
15- PUMP ANTIFREEZE IN THRU CITY WATER INLET TO WINTERIZE CHECK VALVE (REQUIRES A HAND PUMP).
16- IF UNIT HAS A BLACK TANK RINSE, YOU NEED TO PUMP ANITFREEZE THRU IT TO WINTERIZE THE CHECK VALVE.
17- CLEAN ALL SINKS, TUB/SHOWERS. ANTIFREEZE CAN STAIN!!
***MAKE SURE YOUR HOLDING TANKS ARE EMPTY***
***3 GALLONS OF ANITFREEZE ARE REQUIRED***
ALWAYS CHECK ENGINE ANTIFREEZE IF YOU HAVE A MOTOR HOME!
