Not having a manual leaves me with questions that I found are answered by experienced people that are on this forum. My question is, how do you sanitize the water tank more specifically how would one get a small amount of bleach into the tank? The reason I ask is, that we will not be using our rv until March and it had 1/3 full of water. I will drain the tank but would like to perform the procedure before I partially fill it for our trip. Thanks in advance, Boomer
