We remodeled our master bath.
The shower, tub,sinks, and toilet were replaced. It was all plumbed identically with the old configuration, but now we have gurgling noises coming from the new slipper tub when the toilet is flushed. It doesn't happen all the time, but the majority of the time. I have run a bit of water in the tub to keep the trap filled, but that doesn't solve the problem consistantly.
Your thoughts, please
