“Fantastic! I walked in with parts to the faucet in my vintage sink and walked out with everything I needed. Chain hardware stores suggested I get a whole new sink and/or would not be able to do it without a plumber. The employee at Noels took a quick look, knew what it was, and had it in stock. I was able to fix my sink in two minutes with their help! ”

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.

We can ship anywhere the US Postal Service ships. For orders being shipped outside the US, please contact us at (888) ASK-NOEL, noelsplumbingsupply@fuse.net, or via the text widget on this screen.

“Y'all are amazing. I live in Texas and it's faster to order express from Noel's than go to local parts stores. Customers can text Noel's a picture of the part they need and Noel's will find that part or the equivalent and text the link. They have 2-3 day shipping available. The staff answers the phone quickly, politely and they know their stuff! The unit I needed plumbing parts for was built in the 30s. No matter, Noels has me covered. I highly recommend them. Thank you Noel's for your efficient, old school excellence combined with current technology! You have saved me so much time, money, and aggravation! A++++++ ”
