Water heater questions

We just purchased our first TT and have some questions about the water heater. The TT is winterized right now and the previous owners have taken the anode rod out of the water heater. The TT does have a by-pass valve. When reading the owners manual, it says if the unit does NOT have a by-pass valve, then you should remove the rod. Is it necessary to remove the rod every time we winterize even if we have the by-pass? Another thing the manual said is to replace the anode rod every year. Do most people do that? It seems like it would not be necessary, especially when draining the tank after every camping trip and using the by-pass valve each time we winterize. We will probably only be camping a couple times a month for 2 days at a time and would be draining the tank after each trip.

In reference to draining the hot water heater when winterizing. YES, you always need to remove the anode when winterizing your trailer. It is the only way to be sure you are draining ALL the water out of the water heater during the winterizing process. Also, when your doing this, open the high pressure valve on the heater and it will drain completely. AFTER, draining the hot water heater, you can open the bi-pass valve to bi-pass the water heater and finish the winterizing process.
It is not necessary to drain the water heater between uses during the summer. I would, however, drain the fresh water tank after each weekend usage.
The every year anode replacement should be a guideline, not a rule. The condition of the anode when you winterize will determine if it needs replacement or not. Use your good judgement on how much of the anode is "eaten away". I guess I'd replace it if its 35-40% gone, otherwise, use it another year.
Good luck!

I do drain the hw heater after every trip "if" it's going to be several weeks before the next use.
If anything it keeps it flushed out.

As far as replacing the anode rod every year alot depends on the campground water quality and how often the HWH is used. When we winterized last fall and I inspected the anode rod ours had very little deterioration, some where betweeen the first and second pic below.

You can also drain the water heater by removing the anode and opening the hot water faucets all over the camper rather than opening the pressure relief valve. It's a good idea anyway as the emptying of the water heater will draw the water out of the hw faucets/lines.
