I want to thnak both HayZee 518 & Lazy Pup. Both of whom gave me splended and useful ideas that I will use. I stil have a question -
- the water heater I have has only a shut off to the Cold water or the inlet - -I have no shut off to the outlet Hot water.
Question --when I use the compressed air to blow out the water lines, won't the water from the hot water lines be blown back into the Hot Water tank ? If that is not the case then that's great- -if Not What do I do?
Oh yes I have a slab house so the outside house bib will hopefully be the lowest point of the water draining. Since I'll be gone 3 or more months I am having some one redo the drains and commodes once or twice for safety so the sewer gas does not enter the house - -he will also be checking at least once a week the in & outside of the house. The vacation sounds good, but the winterizing is lots of work. I hope is gets better as the years go by.
You sure have been a help THANKS
