Upon arrival customer had a water heater that was installed in 2013 and wanted an estimate to install a new unit. In order to update unit we will have to install a new main water shut off to home. We provided an estimate to update both main water shut off as well as water heater. Estimate is good for 30 days and we can possibly price match with any competitive pricing with our 6 year parts and labor warranty. Thank you for calling John The Plumber! -Shane
