This may be a no-brainer question, but so far I haven't figured it out. Since I winterized myself (compressed air method), I'd like to test everything out before our first trip. Problem is, I'm not...
Our house has an irrigation supply, so I'm not entirely sure if the faucet is from irrigation water (though in hindsight, it's more than likely not since it has water to it and I believe irrigation is still shut off for the winter).
We do use mostly the campground water supply.
I'll use the outside faucet to test and sanitize. Now I just need to read up on how to sanitize the system.
