2016 Crusader 295RST winterizing

[PoppaT]

Attempted to winterize using the air compressor method Saturday. Drained low points. Drained fresh water. Left the fresh water drain valve open. OOPS!

When I tried to blow out each faucet - no water came out. Zero. None.

Do the low point drains work so well on the Crusader that all the faucet lines would be empty too, or did I sabotage the process by failing to close the fresh water drain valve?

drain valve doesnt matter. air leaves water in bottom of lines ,not much but some. if you want to see what water was inlines sftrr air go the rv antifreeze route and see what air leaves water in lines. 2 gallons do most trailers . you still have to bypass water heater or air goes in water heater tank. THATS PROB. WHY NO FAUCET WATER BLOWING OUT.

First of all, don't confuse the low point drains with the fresh water tank drain. Second, air is like electricity or water, all 3 will take the path of least resistance. Since the low point drains are lower than the faucets that's where the air will go first if the drains are open. One place the low point drains don't work so well is the toilet. A quarter teaspoon of water left in the flush valve will crack it when frozen.


Here's how I do mine,
1) Turn off the water supply.
2) Turn off the water heater, both gas and electric.
3) Connect the blowout fitting to the rv water hose.
4) Caution! the water may or will be hot. Remove the WH drain plug.
5) Set the air compressor to 30 psi and connect it to the blowout fitting.
6) With the WH drained, open a faucet then set the WH bypass valves to winter setting.
7) Close faucet and proceed to the next until all faucets are drained, finishing with the outside shower.
8) Leaving the last faucet open, open the low point drains then close the last faucet.
9) Flush the toilet several times pausing between flushes.
10) Remove air hose and water supply hose.
11) Drain black and grey holding tanks.


Since my TT is on a seasonal site all year and can be inaccessible for up to 2 1/2 months.

12) Use winterizing port and water pump to pump in RV antifreeze ending with the toilet.
