Anti_freeze in holding tanks

[charlee]

My 1st time geting the moho ready for the winter.
My question is, should you add some anti freeze to the holding tanks? When you empty them, does all the fluid [ a better word ] get drained out?
Thanks in advance.

As long as you drain it as much as you can, you will not damage the tank by a little water freezing in it. It can't expand enough to damage it. Just be sure it is thawed completely before attempting to use again. Anti freeze in the water tank will take a long time to flush out in the spring.

If you get all the water out you maybe safe with black and gray holding tanks the problem is, is it all out around the knife blades in pipe drains. As you pour RV-Anti down for traps some will get to the blade areas just make sure you add a little more to be sure, its cheap insurance.
As Homer says I wouldn't add to fresh water tank your tank should have a low point drain that will get most of the water out.
Heres a LINK to help with any other questions you may have if not keep asking its better to know than have problems next spring.
