    Might hear from some of our GS HVAC folks on this for their take--
    All good! My company will continue to recommend using bleach until we receive a notification from the mfg or acca Board association, which we are on, to NOT use bleach in drain lines.
    But like you said if not comfortable with it then use vinegar. It's just a drain line lol.

      x2. I'm way overdue, just never think about it.

        It's just the condensation drain from the pan straight out into the sewer pipe.

        Is the drain cleaner a no no? I waited about 15 minutes and then poured 5 gals of hot water down it.

            I used to use bleach until my AC guy told me not to. He said to use drain cleaner.

              My hot water heater is between my two units in the attic. Every January when its cool up there I flush the water heater useing the hot water to flush the ac drain lines and secondary lines. Kill two birds with one stone.

                I would say just stick with the bleach. Its been the "goto" method for years and works. If it get to the point that you have to use more just give us a call

                    Had to do this for a client on a house we closed on last week. Calcium build up was causing the float to stick- air compressor took care of it.

                      3% hydrogen peroxide from your medicine cabinet is best. Then as an ac guy we then blow the drain out with CO2. A huge wad will usually come flying out.

                      Bleach is non effective against a biofilm. It also releases gas that can destroy the coil and drain pan as well as other stuff. Bleach can also damage PVC and old glue.

                      I have never heard of vinegar. Not a disinfectant or sterilizer at all so I'm not sure what it will do.

                      Drain cleaner (sodium hydroxide) again is not a disinfectant so it shouldn't be very effective unless you have hair or something in the drain.

                        Thanks for that tip. I built a koi pond that is kept full by the ac water discharge so can't use any chemicals. Never thought about using a vacuum instead of compressed air. My koi thank you

                          Just a FYI hydrogen peroxide will not affect the fish. My friend has a feed line from his well treatment system that uses 35% hydrogen peroxide. The fish fight over each other to stand in the stream. It's good for them. Cleans their gills and kill ick and bacteria etc...

                          You could also use a flexible hose like off the vacuum to divert it for a few to clean it out.
