There is water coming up through the a/c drain when the kitchen sink is running or the dishwasher. We have tried to run a plumbing snake and a water hose up through it to get whatever is clogging it up out but they won't go around the turns. It is coming through into the house through a closet and into the a/c closet in the garage. Does anyone have any ideas what might be going on and how might we go about fixing it with/or without calling a plumber? Thanks
I am not sure I understand description of your problem. Is there PVC condensation line, that is connected to your kitchen drain inside your cabinet - filling up with water when kitchen sink is in use? How can you tell this is happening ?
No when the dishwasher and the kitchen sink is running, there is a water backup coming up through the a/c drain where the condensation runs from the a/c... but it is connected to the sink. There is water backing up through the a/c drain... we are trying liquid plummer to get whatever is clogging it up. I hope that is a better explanation.
Please, tell me: how do you know there is water backing up into your condensation line when sink / good are in use? Is it only assumption ? Is it overflowing at the AC location? Is AC in the attic or on the ground level? How far is it from the sink? Condensation lines are usually PVC pipes and glued together all the way to the unit itself. They continue to be glued all the way up to your AC unit. Please be more descriptive.
The way I am reading debbiet"s post is that water is backing up through a floor drain in the A/C closet where the A/C condensation drain is.
If I am correct the blockage is in the kitchen drain and suggest removing the P trap under the sink and snaking the kitchen drain line.
If this is the case than I think her condensation line is not connected correctly. I has to be connected above trap to any trapped plumbing fixture in the house.
Yes, but with an approved air-break/gap of 1" to prevent the very scenario she describes.Quote:

O and it only started happening after we got the a/c fixed... that's the weird thing. I say call the a/c people and ask them what happened but my husband doesn't want to
Maybe, AC people could reroute this PVC pipe to different location...
O and the a/c is at ground level in the garage and the sink and dishwasher is about 4-5 feet away from the a/c in the garage... there is nothing backing up in the sink it is backing up into the a/c condensation pipeand when the sink is running, the water comes up out of the a/c condensation pipe... sorry I am not very good at this description I don't know exactly what I need to tell u... hope this helps
It sounds like they hard piped the condensate drain directly to a drain pipe.Quote:

In this case I assume your AC pan sits lower than your sink. When you sewer backs up water column comes up and shows in the AC pan first. That tells me that your kitchen sink pipe is clogged up and needs to be cleaned.
That's what I suspected from the very beginning...Quote:
