Fresh water tank and pipes

This year after sanitizing the fresh water system, I have found out that I cannot travel all summer and will resume travel in the Fall.

Not sure if I should leave water in the lines or if I should drain everything and also low point drains for the water lines, or just keep the lines full with the water that is onboard already?

2 things that I question is algae forming in the tank and water lines and if I drain everything will it dry out the seals in the faucets and toilet and cause leaks down the road?

Seems that even if I add Clorex while just sitting for 3 or 4 months it coulds also hurt the plastics in the tank or lines and affect the seals as well.

Any thoughts on this subject would be helpful.

Water in the sanitized tank will be fine. You can even drain the tank if you want....but I favor leaving enough in the tank to run the faucets every few weeks to keep valve (like the toilet) lubricated. You will not need to add any additional bleach. When you go to use the MH again....flush the tank again and perform a re-sanitization.

My theory is that the inside of all the pipes and tanks become coated with a thin layer of very fine clay that most municipal water plants can't remove completely. While that layer stays wet, it stays in place but if the tanks and lines are empty, the layer dries out and curls up and then can later block screens and valves.

If you will not be using your trailer for 3 or 4 months I would drain the fresh water tank and hot water heater and blow out the lines.

I would not leave water in the system that long.

I always add bleach if I am not going to use the water for more than a month. Only takes a small amount to keep tanks and lines free of any algae or bacteria. There are many articles and blogs for the amount of bleach to tank size.

I'm considering one of 2 options after getting all your comments.

1. draining completely including the low drain points and just leaving the tank and pipes dry.

2. Fill the FW tank with fresh water and ad a small amount of clorine and keeping the lines full and then going to the trailer every few weeks to circulate the water thru the system to keep it fresh. I filter all the water going into the tank so sediment should not be a problem.

Right now the system is dry. I'm tempted to just leave it like that till the next trip.

I see that I'll need to think about this one for a while.

Thanks everyone for posting your thoughts on this subject. I hope to hear more opinions on this thread. I'm interested in hearing if someone has had a problem doing either of the above and if so, what problem did it cause?

I have been doing this for years to keep the water fresh. My RV dealer taught me this trick. When you fill the fresh water tank add some lemon juice to it. It keeps the water fresh indefinitely and it won't get funky or let stuff grow in the lines or tanks. I use one quart of ReaLemon juice to 80 gallons. It really works. I have gone six months and not used the water and found it to be just as fresh as the day I filled the tank. I can barely detect the lemon juice in the water, but my dog won't drink it. lol
