Getting the van ready for 2 weeks time I put some Miltons in the clean water tank last week, I've used it for over 30 years and had no problems. Put a gallon or two or water in the tank and purged the taps all good and clear. Pump ran dry so filled the tank to check for leaks. Today checked the taps all good and still clear. Checked the tank and almost empty. So the panic sets in where can I get one, how much and can it be installed without taking the MH apart! Wait a minute did I close the heating valve, did I heck! Still saves drain down prior to fill up next week. Other than that I'm all ready - Woodside Field here I come woo hoo - well almost oil change to do then all set, oh and restock after last years draw down.
