I experienced localized plumbing issues after the Houston freeze. The plumber said if I wanted to try to fix it step-by-step, I should buy a new faucet first, which they would replace. If that didn't work, JM would replace the stems. If that didn't work, I should repipe my entire house. My faucet is under full warranty and is 2 years old and the stems are the same age. Pipes under the sink can be backflushed before stems are cut. More diagnosis is needed before repiping is done and then my entire house probably doesn''t need repiping for a localized problem.
