Leaving Water in a Hot Water Service

The instructions for my Suburban say to drain it. Never have though.

Never drained our gas Truma in 8 years.

Hi garytee

There are differing opinions on this, but we store our van with full tanks (including HWS). Our reason for this is when drained the tanks don't dry out, they remain wet. Add lots of oxygen from a tank full of air, a warm climate, it must promote uglies to grow. So we store with full tanks (minimum oxygen) and twice a year we sanitise the system. Again there are differing opinions on that - different subject discussed elsewhere on this forum.

If you have a clean system(ie, recently sanitised) I think 8 weeks stored full will be ok, just depart when you're ready.

If it's been a while, either sanitise and flush it now and store full then leave in 8 weeks, or store full and sanitise and flush before you go.

My thoughts only

Cheers

I drain the water from our Suburban gas HWS, remove and inspect the sacrificial electrode, replace if required. It's amazing how bad some of the water in NW of WA is (:0).
I then leave the HWS empty and top up the two water tanks with our tap water after flushing any water left after the trip.
Works for me.

Also- check that your HWS may have an anode installed.
This needs sevicing/replacement as required!!
