The Kohler GP500520 is a replacement Pressure Balancing Unit (PBU) designed for Rite-Temp single-handle shower valves. It maintains a constant water temperature by balancing hot and cold water pressures, preventing sudden “shower shocks” if someone elsewhere in the house flushes a toilet or runs a faucet.

“I was very happy with Noel’s Plumbing. I was searching for a fairly rare part and saw it listed on their website. After placing my order, I was informed that the item was actually on backorder. Noel’s Plumbing was upfront and honest right away, letting me know it might take some time to arrive. Throughout the wait, they consistently kept me updated, which I really appreciated. When the part finally came in, they shipped it out immediately. It arrived exactly as described and was precisely what I needed. Excellent communication, honesty, and follow-through. Thank you, Noel’s Plumbing! ”
