I’ve been there — last month my shower did the same hot-to-ice routine and I almost slipped trying to escape the blast. A few days later I found out a valve was sticking and it made me wonder what else was acting up behind the walls. If you’re trying to budget for an inspection, this breakdown helped me get a realistic range without any salesy stuff: how much does a plumbing inspection cost near me . Catching my valve issue early saved me from a way bigger repair later.
