So this is a new one on me. New neighbor called and said he is getting a sulfur smell from the COLD water faucet in a single bathroom. Not hot and no other faucets.
This is new construction and new well, maybe 6 months old. All equipment and plumbing lines are new. PEX distribution and has two full house filters. One is a sediment filter and one is an activated charcoal filter. This is faucet closest to the filters.
It has me stumped. Any ideas?
