I'm trying to sanitize and flush all the drains in my Thor Ace 27.2.

I can only find a hose that appears to come from the fresh, down thru one of the cargo bays, with a valve, then down thru the floor of the bay. and it does drain the fresh.

I can also drain through the outside shower on the other side, and that other side also has the hot water heater, and other than the pressure relief valve, cannot find any drain for the HW, and cannot find any other drain that might be low water drain point as I've seen referred to in many other posts.

The dealer is clueless and worthless and their pre delivery walk through didn't discuss anything more than showing we newbies what buttons do what, inside the coach.

So, if I drain the fresh water, and open the hot and cold on the outside shower, will that drain everything to give it a fresh start?

Thank you.

The hot water heater drains by removing the plug at the bottom. It most likely is a white plastic plug.

As for the low point drains, that drain your lines, you should have at least two. One for the hot and one for cold, depending on your coach you may have another set. On my 29.3 ACE I have one value behind the outside shower set up. Thats between the pump and the shower. I have a hot and cold one located at the outside kitchen area. The best way to find is to look under the unit for small tubings coming down.
