I know this is probably at this website somewhere but I cannot find it. I live in a home that is only 5 years old but whenever someone flushes the toilet when I'm in the shower i get scalded! This never happened in my old home. Is there something I can install easily or would I have to call a plumber? I believe it's called an anti-scald device, but when i looked in the archives at this website I saw only commercials for other plumbing needs. Thank you!!
