Winterizing

Well wasn't expecting to have temps in the low 30s later tonight or snow today - We live in central Jersey - fretting that something will freeze - was going to winterize next weekend. Think we'll be okay?

You should be ok...., but you can always open the low point drains, open faucets, and pull the plug on the HWH.

Kind of depends on how long the temps will be below freezing. If just an hour or so, you will probably be fine. If it sustained for more than 4 or 5 hours and no sun, then I would do my best to get it winterized.

I just winterized mine this weekend using the compressed air system, really easy to do for my first time. I added a little safety facture and used my water pump to put a gallon of antifreeze in the pipes. If you use the compressed air system just remember to set the output regulator to no more than 30 psi.

Exclamation Freezing conditions

Freezing is a serious problem. When you live north of 49th, winterizing is a must.
Remember!!!!!!!!1 to suck out the water from the hot water tank.
The manual says that draining or the air pressure system is ok.

The drain plug for the hot water tank is not on the bottom of the tank. There is always about a gal left. Air pressure system only removes to the level of the water line leaving the tank.( not on the bottom).

A frozen then split tank is not covered under warranty!!!

Tanks that are installed are not always top of the line manufactured parts. But they pass jayco standards.

I have had a tank freeze and split and the repairs cost me over $600.

Be deligent!

Northof 49,

Welcome to the Jayco forums.

Your correct about some water remaining (about 2 quarts) at the bottom of the tank after draining, and Atwood does address this in their documentation stating:

" WINTERIZING (FLUSHING) INSTRUCTIONS:

4. Replace the Drain Plug and close the Pressure Temperature Relieve Valve. The approximately two quarts of water remaining in the tank after draining will not cause damage to the tank should freezing occur."

Winterizing:

I agree that winterizing according to manufacturing specs is always a must. These instructions are always based on properly built equipment that has been installed into your trailer.
Hot water tanks are well insulated with a styrofoam outer jacket.

The tank itself may not always be, in my opinion a well constructed unit, leaving flaws in the welding done at the bottom of the tank where the water sits. Any water expands when freezing for a long period of time occurs. Since you cannot see the tank to make a good judgement call,

again, be diligent, drain the tank completely. And save $600

Welcome to the forum, North! Is that what happened to your water tank, the amount of water left that would not drain froze and split the tank?
