Need a little help with water smell

In early spring I ran bleach through the entire plumbing of our 2011 390BH including the hot water heater. We have taken 2 short weekend trips and everything was fine with the water. Now we are up in Mount Rushmore for a week and turned on the hot water and it smells like rotten eggs. The cold water smells fresh it is just the hot water. How do I fix this there is no way the wife is going to use the public showers.

Also could someone tell me what size socket is used to remove the drain plug of the water heater.

I will have to check the responses in the morning since the campground we are in only has WIFI at the office and not the whole campground

Thanks for your help in advance

The rotten egg smell is sulfur the park where you filled up probably has some sulfur in their water. The longer it sits the more you will notice it and when its heated it will be more noticeable. Drain your tanks including the HW, refill the system with water and chlorine run some thorough the system including HW. Let it sit overnight then light HW next day. It should go away after this but if not it will in time.

Think about things before you do them make life easier not harder.

You may want to drain the low point drains again. I have had an issue with our park model and the washer connection, antifreeze mixing with chlorinated park water causes similar smell.

90% of the time it is bacteria in the water heater and it puts out a bad sulfur smell. It is not harmful. Google it and you will find what to do. I had the same problem and put a mix of bleach and water (can't remember the ratio) and let it stand for 24 hours. It will get rid of it. RV stores also have a product you can use. Flush all hot water lines after.

The manual is clear on "odor"; sanitize your system (not just the water tank).

How long did the water sit in your system since the short trips in spring? If I won't be in the camper for a couple weeks, I drain everything so the water does not ferment and get nasty smelling.

Need a little help with water smell

In all probability, the water heater anode takes a 1-1/16 socket. First, release any pressure in the heater by pulling the release valve, then screw the anode out. You may need an extension on hour wrench. After you drain the heater, put a little teflon tape on the anode threads to help seal it when you screw the anode back in. DON"T reef on it; just snug it up! Good luck.
