Upon arrival customer wanted water heater replaced due to age. Water heater was 10 years old and had a corroded dielectric nipple on top of tank. We removed and replaced 50 gallon 4500 watt water heater with new 40 gallon Rheem tanked unit .We will placed in new pan and repiped t/p relief. Water heater is backed with a 6 year parts and labor warranty. After installation we tested for proper functionality. Thank you for calling John The Plumber -Shane
