Customer had leak on polybutylene water service. Suggested to replace line due to material being outlawed in 90s. Also found TET to be bad and improperly secured. Replaced thermal expansion tank with bracket secured to wall. Also ran new 1” water service and tied back in with new ball valve in crawlspace. In addition, added personal shut off after meter inside new irrigation box. Back filled trench to rough grade to allow for natural settling of dirt. Checked all work for leaks and proper function.
