[QUOTE=GLM;250856]I have several floor drains with trap primers connected. They seem to have a constant flow and have recently started spitting out enough water into the trap to make them gurgle from the splash. Why might this be? I have previously had very high water bills, but could never find a leak and suspected the sprinklers, but now I think it's these floor drains. Why would they need to have such continuous flow? Is there anything to adjust? I don't even know where they would be connected and hope it doesn't involve tearing up concrete floors.
Trap primers should not have a continuous flow, they should have a slow drip. They should be located at a water source next to the floor drains. Look under the sinks in the area of the floor drains. Depending on the make, you should be able to get a rebuild kit to repair them.
