Low point drains

I have an 08 25 ft with slide out. decals show two low point drains but I can only find the one that drains the water holding tank. Does this one also empty the wayer lines? or where could the other be at? have a piece of tubing that is located at the second low point decal but thereis no valve etc. to open.

I am unsure about the decal location what model is this maybe someone can chime in. as far as draining the water lines, the easiest way would be to run the faucet until it's dry but you have to watch it because you shouldn't run the water pump dry. if you are winterizing you would run the water out until the antifreeze shows.

The valve at the tank will only drain the tank....not the rest of the lines. The other low point drain, the valve should be straight above the outlets. More then likely the valves will be inside the TT. Not sure where yours are, but mine is at the rear of my TT. I have to lift up the corner bed and the valves are right there. Hope that helps

Hmmmm....

On my unit, the fresh water tank and water pump is in the front, under the bed. I have two drain valves there, one for the fresh water tank, the other is on the water line that comes off of the output side of the water pump. There is also an overflow tube from the water tank. All three of these drain lines pass through the floor of the trailer. The picture below is one I took when I was installing an accumulator tank in my trailer.



You can see the clear vinyl hose (the overflow for the water tank) passing through the floor. Right next to it is the drain valve for the water line. The drain line for the water tank is to the right of it but you can't see the valve because it is obscured by the water pump. The other vinyl hose (the one with the pink water in it) is the suction hose for putting the RV antifreeze into the water lines when you winterize.

I have a rear water drain also. It's near the hot water tank.

I think the easiest way to find where your drain valves are is to crawl under the trailer and see where the drain pipes pass through the floor. Those with valves should be close by.

Learn something new every day. Thanks for the pics frank this is how my Jayflight is set up.

For those who are interested, here are two more pictures of the accumulator tank installation that I did in 2002

before...



...and after



The installation of an accumulator tank reduces the amount of on-off cycling done by the water pump. Newer (and, of course, more expensive) water pumps run at a variable speed, thus making an accumulator tank unnecessary. The shut-off valve is used to eliminate its use when hooked up to city water and prevent the tank from filling with antifreeze when winterizing.

I purchased the tank at Home Depot and the fittings, pipe and valve at an RV dealer.
