Low point drain

Dana

2nd time out in 2021 tab 320.  As I was filling water I noticed a trickle coming out of low point drain on the right.  Valve in Nautilas compartment was closed.  Didn't do that the first time out.  I shut water off when the inside gage read 2/3, as I was only going out for a quick one night.  When I got to camp the water gage read low.  I had enough water for a night but.......it did get to that 2/3 point pretty quick.  Have to fill completely?  Why the trickle from the  low point drain?

I am not sure how filling your fresh water tank would impact your plumbing, unless the pump was running and you had a faucet turned on.  I do know that it is always recommended to use a pressure reducer when using water from a spigot as excess water pressure can produce leaks.  

The tank monitors are not completely accurate.  Keep in mind the level of the TaB will change your readings.
