I have a brand new home (well 1 year old now), in Northern California. This time of year (today in fact) it rains. When we have a decent rain, our drain pipes are very loud...loud enough to keep us awake at times (especially the kids).

I was told that placing kitchen sponges in the drains would help ease the noise, but they ended up coming out, or sliding down to where it never helped at all.

Is there something I can do, change, or add to help us all sleep through the rainy nights?
