My humidifier collects about 4 gallons of water a day. I keep throwing it out and use indoor plumbing to water my plants. Is is ok to use the water from the humidifier?

You can certainly use it on your houseplants.
Your Dehumidifier.
My friend pours the collected water in the washing machine.
Is that cool?
I always use the water on my plants, but it is from my dehumidifier.
@ibstubro That sounds like a good idea. After all, it is water that is already paid for. At least I won’t feel like I’m paying for it twice.
I figure I could also use it to put in my toilet tank. At 4 gallons a day, that will save me 120 gallons or more a month.
@Pandora I think your toilet tank is the place for the water. WE have no lower toilet or sink.
@ibstubro ?
So you have a toilet tank but not the toilet bowl?
If you are really concerned about the toilet you could do what I do. I put 40oz of PBR halfway filled with fishtank gravel and capped in the tank. It uses about 1/5 less water per flush and I haven’t noticed the flushes being worse.
I live in a apartment and don’t pay for water but it seemed like the right thing to do.
I’m not concerned about the toilet! I just mentioned that it may be a way of conserving water, since the dehumidifier sucks up so much water. I just think it would be a waste to let it go down a drain without it being of some other use. At first I was thinking to use it for my plants but they aren’t going to drink 4 gallons a day.
The washer is a good idea, and it got me thinking that the extra water could be used also in the toilet. Originally I was just going to attach a hose to it and let it drain out of the laundry room drain, but I figured this sounds good for the environment and my wallet.
If your dehumidifier makes 4 gallons per day, odds are your environment is relatively humid and your plants don’t need to be watered so often. That water is great for them since it does not contain any chlorine.
If you have the patience and the energy you can turn off the water to the toilet and pour it into the holding tank. A new toilet is about 1.6 gallons per flush. The older ones are 3 gallons per flush and the “ancient” ones can be 5 gpf.
I too was wondering about the four gallons. Are you starting to grow gills?
@gailcalled, It is in my finished basement. i am surprised that there is no mold. But I love how the room feels now. There isn’t that sticky feel.
@LuckyGuy It does explain how I had a plant that didn’t die down there when I moved. It was behind some boxes when I moved and it took about 2 months before I could get to it to water it. Funny enough. When I moved it upstairs where it was drier, it died, even though I gave it water.
