Came out for water heater not working. Was able to get the water heater lit, but the tank was from 2010. Customer elected to still replace the tank due to the age. Water pressure was at 100 psi. Received approval to replace the PRV as well. Set new pressure to 50 psi. Ensured proper function and a leak free install. No further issue at this time. Thank you for choosing Chen plumbing.
