"Easy"
Drop in replacement for 2005 White unit that just started leaking leaking. Setting Thermostats on the new Rheem was a little touchy but overall now working as it should. Easy online purchase and pickup same day. Next day purchased hook-up pipes locally, installed it myself and had hot water by noon.
"So Far So Good"
So far so good! Installed 2 of these in tandem for a 5 bedroom 3 bathroom house. 30 minutes heat up time from start. No thrills hot water heaters, so less fault points, but nothing fancy about them. Don't use the HD install kits, junk. Shark bites and an hour later after drain time and removal of the old units - I'm done. I'm not a plumber or an electrician, just a DYI guy and this was a snap. 2 months in with 2 adults and 3 teenagers, haven't ran out of hot water yet!
"Easy to Install"
Highly recommend. Try to do everything I can around the house, so when our hot water heater started leaking I chose to do the same. Looked at a few videos online and very easily done. My previous tank had relief from the side which was the only thing i did not get dueing initial purchase. From the time I started till running hot water through the faucets in the house took around an hour and a half. Easy project with very little mess.
