That is not true, just because the T&P is on the side does not make it "only" for a mobile home. The wattage of the elements is the difference. :doh:Clay -- thanks for taking the time to call me back yesterday, and again my apologies for jumping off the phone so quickly.
Yes, the Whirlpool WH I picked up from Lowe's only has 2 openings on top (hot and cold), 1 part way down the side (T&P), and one all the way down (drain).
Not gonna work. :doh:
So I returned that one to Lowe's and found out that WH's with the T&P on the side are for mobile homes. Why? I don't know. But that's all that they carried. So off to El Cheapo (Home Depot) and an extra $50 for a water heater that I can actually use.
Thanks to everyone for all the help. I couldn't go down this path without it!
Some manufactuers choose to put the T&P on the top and others on the side, there is no difference whatsoever in the tanks, jackets, or constuction of the W/H.
Sorry for the rant, I can't stand it when one of the "EXPERTS" at one of the big boxes make assinine statements.
