I've got a 40 gallon Rheem tank. Not too long ago it quit heating as well as it used to, by that I mean in the mornings we're lucky to get more than one relatively quick shower with hot water and it's a good hour before you can get another 10 minutes tops hot shower after. The tank is electric, I've replaced both the top and bottom elements. That did not solve the problem. I've tested both elements and they are both getting 110 volts. The thermostats seem to be firmly positioned on the side of the tank to the best I can tell. At this point I'm stumped on what the problem could be. I'm trying here before I go out and buy a new tank. One last thing, I've noticed brown water occassionaly, maybe once every couple of months. The house is not that old, maybe built in the late 70's or early 80's so I think it's correct to assume most of the plumbing is done with PVC and copper? When I changed the heating elements out (about 3 months ago) I flushed the tank completely. I'm beginning to wonder if the dirty water and the hot water problem are some how related.

Another possibility is a broken or disintegrating dip tube, especially if the tank was made between August 1993 and March 1996, but also if it is older than 10 years. If it is that, it is a fairly simple fix. At the same time, though, you ought to check the anode. The brown water could be indicative of a depleted one. If you let it go too long, you'll need a new tank anyway. Randy Schuyler

Hello: Normally heaters run at 220 or 240 volts, not 110. Check incoming power from the breaker panel and tank specs  Yours, Larry

I had the same issues and it was a broken dip tube. With a broken dip tube, water just flows at the top of the tank, which is the reason for the reduced hot water. For me, one of their "kits" and a couple of hrs to install and I have hot water like a new tank would deliver. See my posts here http://www.thetankatwaterheaterrescue.com/forums/forum3/1505.html
