Alde Pump Setting: Gurgling

RetireeBC · September 2022

Greetings all. I recently had my Glycol changed and am now getting a very noticeable gurgling sound at the Glycol tank. Heating is working, but there is now the loud gurgling noise. The system was silent prior to the service. I am wondering if the pump setting is the problem? I checked the manual but did not see comment on the pump setting. I did see a Youtube video that made reference to setting the pump at 2 to reduce noise; although they did not say what noise they were addressing. The pump is set at 5. I would appreciate your input.

Cheers

Yes, the excess pump setting results in churning in the glycol reservoir. Manually turn the Alde pump down to 1.5 or 2. Do not try to adjust it via the Alde panel as it is not functional for this task. The pump is set to 5 with the exchange to expedite air removal.

Where is the Alde pump?

@jalars8 Pictures in this thread. The pump is about the size of the palm of your hand, and might be obscured a bit by pipes, etc. Basically, right on the driver's side of the Alde. https://tab-rv.vanillacommunity.com/discussion/6203/alde-circ-pump-setting/p1
