We just moved into our house. It was built in 2012 and was a Parade winner (so I'm guessing it was built fairly well.) The Home has 2 50 gallon Rheem water heaters, and I *think* a recirculation pump (I don't know what this is, but there's one plugged in next to the water heaters). All sinks, except the kitchen faucet and the showers, have a separate cold / hot water handles. The home is fairly large (6000 sq ft), so there's a lot faucets and bathrooms etc. We just moved in 2 days ago and the hot water is so sporadic. Here's a few of the issues: * Sometimes hot/warm water comes out when it's supposed to be cold. Sometimes the opposite. * Sometimes we get NO hot water (and this is with nobody using any hot water for hours). * Sometimes the water is too hot, sometimes the water is only lukewarm (nobody previously using any). Sometimes it's too cold. No rhyme or reason. * Master shower has 4 heads, all with separate controls. If only one is on, all is well. If we use any of the others while using that one, they both alternate between scalding hot and freezing cold. * All sinks/faucts/showers/baths exhibit this behavior, so it's not limited to a select few. * Sometimes everything works perfectly. We contacted the previous owners and they said they have never had these problems. Pilot lights and burners in both water heaters seem to be functioning normally. I've tried unplugging the recirculation pump, with no improvement or change. I contacted a few plumbers, but the earliest they can get here is Friday (it's Monday). I have 4 girls, plus the wife - so you can imagine my pain and all the complaining I'm getting. I'm not super handy and don't know a lot about this stuff, but If I can fix this myself, I'll do it. I can take some pictures of the utility room if it helps. Thanks for any help!
