Bob125 Posted August 26, 2022 Share Posted August 26, 2022 Need some help. I’m at the end of trying all I know to do. I’ve confirmed the AC condensate drains are working and running into the hose to the ground (the one embedded in the roof and side wall eventually exiting on the roadside front). I’ve vacuumed and confirmed the hose from roof to ground is clear. I have also run water from the ground via the hose up to the ceiling end. All clear. After running the AC a few hours with lots of condensate water in the hoses (and on the rooftop cause it’s not draining), the water does not travel from the AC down the hose, all gets backed up in the roof cavity where the connections are made. I disconnect the AC drain hose in the ceiling and water comes out of the [roof to ground hose] like there is back pressure, bout the pressure of a water fountain. For some reason the gravity head pressure of the AC drain height is not enough to push down through the [roof to ground] hose. At this point I’m thinking the [roof to ground] hose must have a hump in it where the condensate water must go uphill. If that’s the case, I guess I have to just live with it as the [roof to ground] hose is embedded well into the roof and sidewalks. Anybody have any other thoughts? Possibly some type of vacuum is being created? Thanks in advance for any ideas, Bob… Link to comment Share on other sites More sharing options...
