    upload_2019-2-9_17-20-26.jpeg What is this pex tubing under the bathroom sink? That is an external wall. The other pipe going out the same way is an oudoor faucet. There is a bad small from that tubing. The sink water has been turned off for several years. It is an unused bathroom

    Bad smell means it is probably a vent homeowner added). I would plug it and see if any other drains in the house are affected.
