Air tank problems.

[johns4104s]

The wet tank (front drivers side) was making a rattling noise, over the pit I found air and water bubbles leaking from the top of the large brass one way valve# 223 (which has a arrow pointing down). Taking this off the tank. Also on Checking the bottom valve, Expello 24 volt M/L #995106. The power (24 volt) was not connected the exhaust outlet had a plug in it?

So I feel I should replace the the the one way valve, hopfully I can get this from a truck supply. The brass fitting joining the copper incoming line though the bottom of the coach is going to be to hard to line up and not cross thread. So I will use flex air hose extend the copper line and with a few turns enter the top of the new one way valve.

At the bottom of the tank I will completely replace the Expello 24 volt valve with a manual pull valve.

Does anyone have any input?

Thanks

Sounds good to me.

Fasten the extension plumbing securely. No potential for movement when you are done.

Thanks, Buswarrior,

I forgot to say the tank was completely full of water and light brown sludge stuff.

You will be pleased with the reduced compressor cycling, less apparent air consumption on brake applications, but slightly longer air up times from empty, now that the volume of that tank has been returned to service.

That is why we drain our air tanks!

The tank had a automatic 24 volt disconnected drain on it. Have you checked yours? What do you have for a drain on your wet tank, auto or manual??

John,

You're really confusing me here - front wet tank and 24v??

What are you driving, it surely isn't a 4104? Must be your MC9.

[johns4104s]

Sorry Gus I should have put it in the post. Its a MCI 9,

MIne are all manual with cable running out to the wheel wells.

I added one of those automatic valves to my wet tank but it never worked. Always had one on the dry tank.

My ping tank never has any water?

I went back to manual with cables to the outside, no worries about freezing this way.

Automatic drain valves are not particularly reliable at doing their job.

Great concept in their designed operation, however, they do not seem to function as intended as time goes by.

For a busnut, in my opinion, manual drains, and watching what comes out, is a better way to go.

With manual drains, you positively know they have worked, and for preventive maintenance purposes, you want to see what it is that comes out.

If you don't see the drainage, how would you know you are suddenly pumping oil or that there is an increase in water?

Put a knee on the ground and watch what comes out!

happy coaching!

Well said and good point BW

Is it normal to have water in your tanks? I check our often, and we are always dry. We also replace the desiccant cartridge every year, so could that have something to do with it?

God bless,

A good air drier will remove close enough to all the moisture to say it gets it all.

John316, you have a good air drier, and well done on doing the desiccant annually!

happy coaching!

Thanks BW. I was wondering!

I just got this year's cartridge. It was from MCI, and I got it delivered for 50 (I think). I got it because I wanted free shipping, and needed one anyways .

God bless,

John
