Easy assembly
Would RecommendBrought a home last year and whoever had hooked up a replacement hot water heater had all kinds of stuff hooked up which made it difficult to hook up our replacement hot water heater then they didn't put a shut off valve on it but we eventually got it (ours) hooked up correctly. So far it haven't leaked or anything but don't want to jinx it at all.
