The Peerless PTR188700‑IP is a reliable pressure‑balance valve body designed to serve as the rough‑in foundation for your tub & shower fixture. Constructed from durable forged brass, it features female threaded inlets and is engineered to control temperature via a single handle—blending safety, efficiency, and ease of installation. Its integral check valves help prevent backflow, and the body includes a field‑adjustable temperature limiter to restrict handle rotation into the hot‑water zone. If you’re replacing or upgrading shower trim without changing plumbing rough‑in, or building new, this valve ensures stable water temperature even when water pressure fluctuates, offering peace of mind in daily use.
