I tried RV antifreeze and that lasts a week. I do not have floor heat. I would think floor heat would make the problem much worse. Has anyone come up with a solution for the problem other than causing a plumbing leak to keep the trap filled? [Reply]   [No Email]

You either have a plugged vent or no vent at all. The vent could also be in the wrong location. The drain is being used as the vent for some reason. [Reply]  [No Email]

Certainly he will stop up the toilet and it will overflow keeping your floor drain adequately filled. Seriously though, if it's really drying out that fast I would be concerned the trap is broken and the water is seeping into the ground under the floor. [Reply]  [No Email]

A roof handles a lot of water. Am I missing something obvious? How would you keep that roof water from backing into your building? As to the original poster - there's got to be a leak in your trap for it to dry up that fast. I know of a church addition that developed a leak in one of the waterlines under the men's bathroom. It was seeping up through a small crack in the concrete floor, and suddenly one Sunday the floor was completely dry. Upon close investigation I discovered a small hole had been drilled in the floor drain trap, allowing the seepage to go directly into the trap instead of coming up into the building first. A brilliant idea, I thought, but after we fixed the waterline leak, we had a perpetually dry floor drain trap because of that hole. I finally managed to get a sheet metal screw in the hole, but it was a bugger, and it still seemed to dry out quicker than the trap in the ladie's room. Thank God for those extendable magnets or I'd have filled the trap with dropped screws. [Reply]  [No Email]
