Owners Manual Air Pressure Method seems wrong...
So I decided to winterize my new 287BHSW by using the Air Pressure Method rather than the Antifreeze method.
Let me tell ya, I followed the owners manual method but no water actually came out of anything! While the compressor was cycling on/off for 10-15 minutes I was sitting there thinking, how in the world should this be working when every single point of exit is open all at the same time???? There's ZERO compression to force anything out. All it did was gurgle a little bit of water in the hot water heater, but even then nothing came out.
Here's what the manual suggests (abbreviated version):
1. Water heater bypass should be off to let air go through water heater, remove the water heater plug
2. Open ALL the faucets in the RV and the outdoor shower
3. Open fresh water tank drain
4. Connect the blowout plug and blow air from compressor for 30-60 secs then turn the water tank shutoff valve to off.
5. Continue blowing out lines for 5-10 mins.
6. Fill the p-traps with anti-freeze.
After a quick Google search I totally changed up my procedure to the following:
1. Water heater bypass should be ON, with plug removed.
2. Closed all the indoor and outdoor faucets except for the kitchen hot water tap (which is the one farthest from where the city water input is).
3. Open fresh water tank drain to drain all fresh water.
3. Turned the water tank shutoff valve to off.
4. Connected the blowout plug and watched as a LOT(!!!) of water that was supposedly already drained (according to the manual), came out of the kitchen hot water tap.
5. Sequentially opened each tap moving from the front to the back and drained every bit of water left.
6. Opened the low point drains to confirm there was nothing left.
7. Filled the p-traps with anti-freeze.
I love my Jayco and so far I think the only defective part I've found is the owners manual - lol!
