Performed plumbing maintenance. While flushing water heater floor drain started to back up. Also found when water heater is heating up water heater is leaking through temperature and pressure valve. Also found no sediment trap on gas line for water heater. Gave customer estimate for expansion tank to stop temperature and pressure valve leaking. Also gave option to add sediment trap on gas line for water heater. Customer did not want to go with the options. Also ask customer if they would like drain divisions to reach out to them. They declined option.
