Re: Awning needs poles. Anyone recognize this type awning?
Thank you for the suggestion. I will do that. Yours looks awesome!
Re: T@B 400 Alde corrosion
The bleeder valve itself is not too hard. Are you talking about the "little black hose" that drops into the "plug" on the floor of the Alde compartment? Those hoses mostly just "push" in to the holes in the plug.
Re: T@B 400 Alde corrosion
So on our 2019 that has the 3020 and the Flow unit there are two pumps as described. When I did my flush I was puzzled until I realized that the rear most pump going to the Flow unit does not run unless the control panel calls for max hot water, and then only for 30 minutes. During this time the main pump (near the boiler) stops running, even if set to CONT. All other times the main pump is all that runs when it calls for heat or hot water.Bill&Suze said:Sharon_is_SAM said:Not sure which pump is for the main Alde and which for the flow, but I think the 400 setting is typically set at 2-3. Can any 400 owner confirm?
I just tried to get good photos of the two pumps on our 2024 400 but I'll admit that it is difficult to do, given the tight constraints of all the plumbing down there. No way that I could actually get eyes on them. The rear pump at the Flow appears to be set at 4 and the front at 2.
I believe that normal operation both should be 2-3 setting. That works for mine. If the pump is set higher than 4 it causes a lot of churning which I believe could increase pressure and cause the overflow to happen.

@barbarella20722, just saw your post...out of an abundance of caution I replaced mine when I rebuilt my system...so far no runs drips or errors.

Re: T@B 400 Alde corrosion
Thanks, I did not notice the bucket before! How much is in it? You mentioned one pump turned up high. The glycol can escape from the tank from that tube that comes from the top of the tank. It drains, along with the air bleed valve drain, from that "plug" in the Alde compartment floor. The expansion tank tube is clear, and it will be easy to tell if there is glycol in it.

Re: Quality Control
Despite the initial laundry list of issues we had I humbly admit that this thing has handled most of what we've thrown at it. We've been on washboard roads, bounced it around on several trips...not babying it at times...and it's been great. With all of the complaints about the Alde not working, ours has been flawless. It was mostly the finish carpentry inside that was the main issue.
We recently camped with my parents who rented a Coachmen class b motorhome. The thing was a 2020 and was falling apart. Granted it was a rental unit but the quality was horrendous. The typical stapled cardboard cabinets, rickety slide outs, etc. Sometimes I do have to step back to appreciate the good things about our 400.

Re: T@B 400 Alde corrosion
If you think the bleed valve is defective, it would have ejected the glycol out under the trailer. This would be very obvious under the trailer. Since you recently emptied and filled your system, it may just be their is/was still some areas in the glycol loop that still had a little air, and the Alde "burped" that air from the expansion tank.
So....how much glycol is under the trailer? How much is in the expansion tank? I would try adding glycol into the tank and observing the valve and the drain.
If you saw the other threads about failed valves.....a lot of glycol was spilled in those cases.
In the DIY Glycol Change file, the whole last section describes "burping" the Alde and adjusting the amount of glycol in the tank as air is ejected.
