Customer had an electric tankless that was not getting the water up to the adequate temperature. Went through the manual and checked everything the book said for possible issues. Could not restore proper service to the unit. Customer elected to just replace it with a tank. Purchased material and installed new 40 gallon electric tank. Tied back into existing plumbing. Ran new t&p through the crawlspace and out of the side of the home. Tested to ensure a leak free installation. Customer is going to have an electrician come out to remove the wiring from the old unit and run power to the new water heater. We bled all the air out of the tank so it will be ready to power on as soon as the electrical is connected. No further issue at this time.
