I saw a show a few weeks ago where the home owner was complaining about his sink cold water coming out warm, and it turned out to be the shower handle. My daughter went to get water from our fridge and realized the water was coming out warm, after checking all the other faucets in the house the we realized all the water is coming in warm. Is it possible that it is my shower handle, it is a one handled valve. Our house is very small, (around 900 sq ft) So the plumbing is all very close proximity, a lot of our pluming and our faucets are all new (with in the last 6 months) our house was in the Joplin tornado, the water has worked fine till now. Is it just a faulty faucet or something else? our bathroom shower is a Delta multiChoice valve trim 13/14 series. Any advice would be appreciated thanks!
