I removed a shower diverter stem from a three handle faucet which had Eljer printed on the faucet. The house was built in 1972 so this is an old part. I have attached a picture of the stem which is 4 5/8 long. Can someone help me find this part or an equivalent replacement part.
Your faucet is a Union Brass. Readily available parts and an excellent quality faucet. Replace the stems and seats at the same time and have a great faucet for years to come.
