2015 Sierra 34CK Fresh water tank level indicators
Hi guys and thanks in advance for any help.
We don't use our fresh water tank much. Only put enough water in to flush the toilet and wash your hands when traveling.
Recently I decided to fill it as a friend suggested. After the overflow had water coming out I when inside to check the level indicator and the lowest light lit but that was all. I've checked it several times since with the same result.
Any quick fixes or do I need to open the belly and check the tank level indicators?
