Are these low point valves?

[jcurtisbrown]

2019 30’ International Serenity. These are below dinette seat and I can’t even see them without using phone. The black and white round objects do sort of look like valves but are nothing like any I’ve seen before. The black one doesn’t feel like it turns at all and the white one, which is a different type, is impossible to get to because of the lines. No other valves I can find. The exit lines are directly below this from so there should be valves.

First timer, and frustrated right now; hard freeze coming in 2 days. Called JC and the tech guy there couldn’t help me either.

Any suggestions appreciated.

You are correct. Those are the low point drains. They turn 90 degrees to open. Once you find the right angle to reach through they are not hard to work with. Are you pumping antifreeze through or blowing out with air?

We have a '19 International and yes, they are the low point valves, they are tight first time you turn them.

Plan to blow only. I don’t see how I can get the right angle though. I can only get one finger on the white one. Wonder if I will have to take the whole seat out to get better leverage. Assuming they open counter clockwise?

And why are the two valves different from each other?

Different colors are for hot (white) and cold (black) water. They are made different for temperature reasons and are made of different types of “plastic”.

My valves are still hard to turn after several years. And are very hard to reach even with small hands. One I can't even see, can only feel, unless I stick my phone down in there to take a picture.

Mine are hard to turn also. A 1/4" open end wrench just fits the little tab on the knob and makes it easy.

Thanks for the help. Had to do some finger gymnastics but finally got both open.
