Dripping sound in Basement drain
What might cause a dripping sound in a basement floor drain in a cold cellar. Pretty positive there is no leak in the house plumbing. I see water in the trap, and hear a steady dripping sound almost like water is dripping into the trap. But from where. ????
Google brings up nothing. Strange problem!

From the primer? Which is usually the laundry tub faucet

Could be from the weeping tiles emptying into the drain. No issues.

No, very common problem.
Two guys have already identified the most likely culprit, but they've not bothered to explain. What if OP has never heard of a primer? If you're gonna give advice, at least make an effort.
OP, check your laundry tub faucet. Do you see a small copper or plastic line attached to the faucet?
That line is connected to the floor drain. Its function is to shoot a bit of water into the trap whenever you open the laundry tub faucet. That keeps the trap wet, thereby maintaining a seal that prevents air from travelling up the drain and entering the house.
If you don't close the laundry tub faucet tight, it will drip water continuously into the trap. If it's tight and still leaks, you need to change the washer.
Most people find out about this after they get a horrendous water bill.

The furnace condesate is likely draining into the basement drain, as would any humidifier on the furnace.

Thanks everyone. All these responses have certainly put my mind at ease
I did confirm there is a plastic tube going from my main floor laundry faucet into the floor. I can't see where it goes after there but assuming this is the primer. Just need to make sure it's not leaking.
Thanks

You know I had something funny like this and it took me years to solve it. It turns out it was coming from my plastic hose for my air conditioning drain. For some reason the drain hose wasn't angled right and the water I guess was getting caught somewhere and then dripping down on itself. It was echoing into the drain making me think it was the drain. All I had to do was re-position the plastic (pvc) tubing for a good slope of drain and presto no pop pop pop noises..... Hope this helps...it was making me nuts.

We have that. Between the furnace, the a/c and the humidfier I think the trap is getting plenty of water on a regular basis!
We also have another floor drain in our cold cellar and it has a separate primer line.

Just a quick update to confirm 100% the dripping was from laundry room primer. This morning it was dead quiet in the drain, so I went up and turned on the laundry room faucet for a bit. Went back into cold cellar and could hear dripping again.
Thanks everyone.
