Looks like most of my interior plumbing is pvc piping and wonder if
its safe to use a little bleach for a bathroom sink to loosen a clog?
It drains but slowly. I'll probably try a plunger first regardless
but I've been meaning to ask if the bleach is safe for interior
plumbing? My house was built in the late 90's if that matters.
thanks.

The bathroom drains in my 8-year old house have gotten slow. I also
have PVC. I saw a drain cleaning recipe in an RV group that has
cleaned them out. It's as follows:
Mix 1 cup baking soda, 1 cup salt, 1/4 cup cream of tartar. Pour
1/4 cup of mixture down the drain and follow it with 2 cups of boiling
water.
I don't know how it works, but it has helped keep my drains clear
without dumping a lot of chemicals down the drain.
