Bounder: Need some help please on a 35H fresh water tank drain

[Camping4fun]

I have a 2009 35E on the fresh water tank there's a 1 inch PVC line coming out the top into a one way check valve and a line coming out the bottom of the tank with the drain valve handle where you drain the tank and then they connect together. Can someone tell me which way the check valve go's in the top line? There is a arrow on the valve, does it point to the tank or away from tank? I had surgery last week and the wife and son was going to help me out and drain the fresh water tank next thing I know the drain pipe is in 7 pieces. So instead of coming in and telling me what happen my son starts taking the pipe apart to replace it and forgets which way the arrow went.



Thanks for any help

I believe the arrow should point away (out) of the tank. The top outlet is the overflow and you do not want water backing up into there. The lower outlet is the drain line and the movable valve closes it off.
How did it get into 7 pieces😱

This is a different set up than mine, plus I'm looking for the one way valve not the drain valve but you you very much.

Where the 1 inch PVC pipe come out of compartment under motorhome to let the water drain out on ground I put at fitting on there where we could hook up a garden hose. Our motorhome is parked inside so this way we can drain the water out the hose and it don't end up flood under the MH. They had it hooked up to drain tank then decided to back up the MH running over the hose with the front tire that's what they said happened and there both sticking to that story. Thanks

Can someone get a picture of the top line coming out of tank? The one way valve is shaped a little different on one side if I could see a pic I would know for sure. Thanks
