Installed this Hydrosense myself. Couldn't be better... comes with TP valve and heat nipples already installed. They also include foam pipe insulation so you know attention is paid to detail. User manual instructions are very clear as usual from Kenmore. Unit is ultra energy saver and they use 2 anode rods with double insulation. I'm impressed.
