Air purge of water system

[Mike01]

We have a 2016 Jay Flight 29 RKS. When we blew out lines per owners manual we did not get any water or air out of the low point drains. Manual shows 3 toggle type drains, however we can only find two. The manual shows the 3rd one as fresh water drain. Any ideas on why we would not get air or water out of the low point drains or where the 3rd drain may is located.
Thanks
Mike

Did you pull or turn the valve? You need to give them a good pull, I think mine pop up about 1/2".

Did you get air coming out of the low point drains? If not they were not open

Thanks for the input. I could not get them to move up, so I took the valves off. Still can not get water or air out of the hoses.
Going to call the dealer to see if they can help.

Did you have the faucets open when you tried to drain the hot and cold water lines?

My tag that says low point drain are just fresh water tank drains. My 2012 has no low point drains.

Don't know if your trailer is similar to mine, but I have 4 "low point drains". Two are under the vanity in the bathroom and are connected to the pressurized water system. If there is city water connected or the pump is on (and there's water in the fresh tank), these valves will shoot out pressurized water when opened, just like any other faucet in the system. They are T-valves and are pulled up to release. The O-rings on these valves are problematic.

The other two are gravity drains for my fresh water tank. The fresh water tank is not pressurized, and the valves are the 1/2-turn variety. I have 80 gallons of fresh capacity, and when those tanks are full, it takes FOREVER to drain through those little valves.

If you are looking at the FW tanks drains. The tanks are not pressurized when you blow out the lines. I just leave the FW tank low point drain valve open all winter. This way I do not worry about any little bit of water getting down in to the valve and busting it.
