De-winterizing water and AC systems

luvinlife

I am going to de-winterize my water system and AC this weekend. How do I flush water and a little bleach ithrough the hot water tank? It looks like I have only one water inlet on the side of the boat and that feeds the big tank. How about getting the antifreeze out of the AC?  Just run it once I splash?  Any input will be appreciated. This is my first season with the 270.

Fire it up and it will spit it out.that's for the A/C.hot water if empty just flush if full drain frist,to drain you need open the blown of valve and the drain.It takes a couple of times to get it all out.

Just did mine today, first run all the pink out of water tank and hot water heater. Then I ran two full tanks of water on the ground, If you turn on water heater before getting all the pink out the water will stink, like rotten eggs. I always wait till I'm in the water to do AC.

Make sure after you drain the antifreeze out of the hot water heater that you turn on the water pump and open a hot spikot before you turn on the water heater circuit. Even a short period of time that the water heater operates with no water in it will kill the heating element.

With my hot water tank, I opened up the drain and ran the water thru it until the water ran clear.

For the water heater, also make sure you remove any air lock.  The only way to do that (as far as I know) is to lift the pressure relief valve until you have nothing but water coming out.
