Customer had a drip occurring from the plastic union on the shutoffs for the whole house carbon filter. Attempted to both reseal, or replace the o ring, and neither stopped the leak from occurring. Flushed tankless unit since it hadn’t been serviced in the past year and gave pricing to return with new shutoffs for the filter and replace them. Will call when the part has arrived and schedule a return visit. Noted a gas smell when servicing the tankless. Found a small leak on trac pipe line running to the sediment trap. Isolated the gas line and sealed the leak. Tested all work that was completed to test for leaks, no additional leaks were found.
