I have checked on the 2 transparent tubes and there are no holes on the plastic tubes.
Yet sometimes the floor of the basement is moist.
How do I stop the leakage (???) and clean the difficult to remove water marks on the basement floor?
I have a furnace, humidifier and a water heater in the basement.
Martin, without seeing it first hand, it's difficult to say.From looking at the photo, I would question the source of the leak. If, as you said, it isn't the tubes themselves, check the connection at the humidifier and inside the unit for leaks. Quite often these units have a build up of deposits and interfere with the drainage and the proper operation. As to the stains, you can use hydrochloric acid at a ratio of 10% acid to 90% water. (where rubber gloves and mask. Or muriatic acid. Same ratio. this is a tip I've heard of. Key is to rinse and let dry. sorry ... not a great deal of help.
Hard to judge, but try to check if the actual floor drain is maybe somewhat clogged........
or slow the flow to the humidifier a bit .
Check the connections of the hoses to the appliances .
Clean floor with a muriatic acid solution.......and make sure space is vented and you wear gloves and old clothes..........ratio aprox. 10%-90%
If more applications are needed let dry in between coats.
Hope this helps at least a little bit.
