Drain fresh water tank

[philfishes]

2017 Pinnacle refs; Trying to drain fresh water tank. The only place I see is a low point drain on passenger side . Tried to drain tank; water ran: for two hrs.
I know tank does not hold that much water. What is going on?

You likely have a 75 gallon or more FW tank.
I've got around a 90 gallon (2-45 gallon tanks) and it takes an incredibly long time for those tanks to drain out that very narrow diameter low point drain. It actually MAY be normal.

You are probably right. Any other explanation does not make very much sense.

I have an 85 gallon tank and it will slowly drain from the low point drain for 4 days before it empties completely. Now what I do is pump it to the grey tank (leave the shower, sinks on) at the dump station (at my storage lot). It takes about 20 minutes to drain it that way.
