My kitchen sink was back up after the trap and had a professional come out and snake the drain. He pulled out some nasty stuff and after that the flow was fine and no more clogged/slow drain.

3 hours later I went into my laundry/mud room where our HVAC unit is and the floor drain was overflowed! That has never happened to us (but we have only owned the house since May). There is a PVC pipe that goes to the floor drain that is from the HVAC unit but that is just drips at a time. I look into the floor drain and 6 to 8 inches down there is standing water.

What could have happened after the drain in the kitchen was snaked? Could it have clogged this or is standing water normal in the floor drain? Do I need him to come back out to snake that floor drain? My wife took a shower and so did I last night and flushed all the toilets (3) in our house and the water did not go up or down in the floor drain.

Any help would be great. :thumbup:

NOTE: I do have to say I dont remember if when we moved into the house if there was standing water.. I did not look and dont remember what the inspector said. The floor drain does not have washing machine water pouring into it from the top.

Thanks!

If theyre tied into same line before the main it could have shoved something further down line.
Does water in floor drain get higher when running the sink? :)

The condensate from ac drain shouldnt be a big enough load to notice,the sink/dishwasher normally dump into same drain .
Washing machine should be on its own line back to the main :)

Id isolate the loads from eachother to see which one affects it more .
Does anything happen if you flush a toilet in that area? :)

Ok, I ran everything and the water level did not move an inch. Not sure why it overflowed when he did the snaking of the kitchen sink/drain.

Picture of it in my laundry room


Picture of the water level, you can see it is about 8 inches below the top. Standing water.

There needs to be a certain amount of water above the trap for it to seal good.
Id try hitting it with a good plunger and see if it helps :)

So I have ran some more dishes, showered, ran the sink and running the outside hose to water the lawn... looks like I am good. Weird but I will keep an eye on it. Cool thing the plumber gave me a 6 month "warranty" on his work and labor :)

Thank you guys VERY much!

The water in the floor drain is supposed to be there it is trapped like under your sink. It sounds like it backed up while the plumber saw cabling it. If all your drains are running now then you are cool :)
Well over the last month or so it has been fine. It has gotten up to the top level of the floor but never overflowed.... Until tonight



The AC has been running but nothing too crazy. Why is this happening again? Should I call a plumber ASAP?

Before you call n the troops---clean out that floor drain---a simple snake for $10 or less is what you need---often the P-trap gets clogged with lime and floor sweepings----rod it and flush with a pail of water---see if it will take that water---If not---call in your friendly plumber---

Any trees in the yard, where the line runs out to the Septic or Sewer? You may need to have them run a camera through the line to see what is going on, or find someone else to do the work of clearing the line.

There is one true in the front yard... which is on that side of the house in the front out to the street.

Touching base on a old thread (mine) but still having this issue. It started last week when the weather was hot and I was running the AC. The condensate drain overflowed and I used a plunger and it went down a little bit. The next day it overflowed again and I used a siphon to get the standing water out to put a snake down there, but I could not get the snake ANYWHERE farther than what I could see down into the drain.

There seems to be a lot of gunk down there and I am not sure what to do. I was thinking of using a shop vac to blow stuff through but not sure if that will fix my problem.

Any ideas?

If the current issue is isolated to a floor drain only- I'd suggest the smallest cable you can (1/4") and work the trap.
Given the trap design- it's very difficult to cable through- but doable with a small machine.
I have also seen many traps opened with only a plunger....
