Can you help me ID this movie?

Soooo, 25 years ago or more, I was "playing" at a freinds house. We were passing through the tv room. I was there just long enough to be scared for life ! Just kidding, but yes, there was a movie on, A woman in the shower, and well the drain was clogged, She takes this wire coat hanger, unravels it to make a straight wire, and starts poking it in the drain. Next thing you no, blood is shooting up the drain and out the shower head,

Thats all i saw. I have watch hundreds of old chessy movies and never encortered this one again. but Someone out there must have! THANKS!
