I have to floor drains in my basement and there is a small white tube sticking out for them just below the concrete floor and one of the is dripping water into the drain is this normal

If you have 2 drains and 2 tubes below the floor, sounds like someone put a seepage drain pipe in the gravel under the slab. Turn off the water to the house and see if the drip stops. If not, it's probably a drain line. If it does stop, HMM? Would be strange to have a house leak in 2 drains unless there is a supply pipe in the slab.

HI gates...

Sounds like TRAP PRIMERS to me... ;)

Here, some plumbing codes require that if we install a floor drain we install a trap primer to keep the PTRAP of the floor drain wetted so the PTRAP doesn't dry out and allow sewer gasses into the home.

Most trap primers work by dripping water into the PTRAP every time a fixture is used in the house. If the trap primer is connected to a water heater, for example, it could even cause the trap primer to feed at a pretty constant drip rate.

Anyway, look around for a trap primer somewhere above the floor nearby... could be at a water heater, a boiler, or even under a bathroom vanity. For some models (see 1st pic.) there will be an inlet, an outlet and a trap primer tube that disappears into the wall and then into the floor, or something like that. For other models there will just be an inlet and the outlet will go into the floor and connect to the floor drain undeground (see other images).

Some people that don't understand these valves will hide them in walls and you may never find them... see last image... *UGH*!

Care to discuss more? Let us know...

Definitely something we don't see in ATL. I assume the dripping is to keep the trap full of water, Brian

Hi Brian...

Yup! As stated above, "we install a trap primer to keep the PTRAP of the floor drain wetted so the PTRAP doesn't dry out and allow sewer gasses into the home." You will see these mostly on new construction for say the last 10 years or so although they have been installing them for much longer. Here, codes enforcement has been catching flack for not enforcing them so the last 10 years or so the inspectors have been pushing them on new jobs, anyway... ;)

We use them for water heater pans, washing machine pans and floor drains... pretty much anywhere the trap can dry out periodically.

Happy New Year!

Duh! Read the fine print! Happy New Year to you and your family too, Brian

That white tube, where does it go once it is out of the drain? This could be a condensate pump drain , water softner drain, R/O drain.
