Farmboy,
Are the stems you replaced original universal rundle parts? there are a lot of imported repair parts for U/R products and we have had a lot of trouble with them. The number you list 14A is not a U/R number and that makes me think you have imported parts. Universal rundle has closed their faucet division and are offering no parts for any of their products. However there are still some original parts available. Take a look at the Universal rundle parts breakdown on our web site to help with the proper identification and we can see what’s still available.
Good luck,
Scott
