Fresh water tank drains slowly on new 2023 Baystar

[C&M]

When opening the low water drain next to the fresh water tank, the water barely comes out. The tank is full, so it should be coming out like a water hose. Haven't check for blockage in the line yet, but wondering if anyone has seen this and their fix?

Low water drain or tank drain

Make sure you open a few faucets inside to assure there is no negative pressure lock...

I have never seen a freshwater tank drain like a fire hose on any Newmar. My current DS takes about 15-20 min IIRC, and my previous Kountry Star took hours.

That is why the question about type of drain.
Make sure your tanks vent does not have a loop in it! This will cause a negative pressure in the tank.

I have a 2020 Canyon Star, and, when I drain the tank, it is a bit slow!
However, as suggested, open the cold water handle on your sink, and it will increase the flow!
And No, it won't run like a firehose!

Mine is glacially slow. I just use the water pump to pump it out through the wet bay shower connection.

Install a 1.5” pvc drain with a 1/4 turn valve. Dump fresh in just a couple minutes.

There are low point drains (hot and cold) and these drain the lines above the floor. There should also be a tank drain. Typically it is inboard in the wet bay, on the floor of the wet bay and usually hidden by other stuff. Look way inside. Maybe even use a phone/camera to look down, behind the wet bay tray edge. The drain is connected to the bottom of the tank. Not a large line either, but low point drains are not designed to drain the tank.

The tank drain is 1/2", with only having the height of the water in the tank for pressure. So it is not going to be speedy. If I have other things I need to do, I will open the tank drain and give it 20 minutes or so. If I need to get moving, I open both hot and cold low point drains and turn the pump. That is quite a bit faster.
