Plumbing and Big Brother

You can adjust 'max' heat by removing a 'security' ring, then move it 1 notch hotter.

I adjusted it a couple hours ago . Just took a phillips screwdriver and a small allan wrench . No clue on actual temp , but I like Hot showers . Felt hotter on my hand . They're both Delta faucets . Actually had directions on the valve body . Thanks !

All the showers and tubs in our house have the dual knobs for water, I hate them, much prefer the single knob .

Guess I shouldn't complain, sure don't want anyone getting burned. Thanks everyone

My grandfather would say "let them burn". Today we try to make things better, safer. Not easy to do . Water heaters are much safer today but are a lot more problematic. Half of the water heaters I replace are mainly due to safety features that have been introduced in the last 25 years. I tell customers the government has made you safer but you don't have any hot water because of it. I ask them would you rather have your house burn down or get scalded? They have been inconvenienced but are safer. Guess I would rather be safer.
Didn't mean to hijack your post. AC in SC ,Deltas are good faucets .There is usually a white plastic piece behind the handle with splines. Spring-loaded and you can pull out and rotate a few splines to make it hotter. Sounds like you already figured it out. I adjust them as hot as I can when installing. Our inspectors are not as thorough as Plummerscarrin . They never check for temperature on inspection. Might get one to feel it with his hand .
Might want to check temp on water heater. These new scald proof faucets mix cold and hot weather you want it or not. Govt wants temperatures set low at heater. May need to turn temperature up a little. Be careful though. Handicapped, elderly, infants and mentally Handicapped may not be able to sense temperatures like the rest of us. Also if you fall in shower and hit the lever as you fall you could get scalded or burnt before you can get it turned off . Most of these rules the government throws at us are for our own good, just seems like they overdo it . Especially when you have to take a cold shower.

Most of the changes are trickle down thru the government regulations driven by insurance companies losses from a lawsuit. Not going to change but the problem is its driving the costs up beyond affordability for many and increasing the fail rate with complexity. Bad combination for the consumer/user. Rear view camera mandates in vehicles is from fools backing into people and property. Can not figure out why we need power windows though, never had to replace a manual crank mechanism. Cheaper to make only 1 kind? 

As part of building inspection classes we had to have a plumbing awareness classes to so call spot errors before issuing a certificate of occupancy. 
 The Master plumber instructing that and i butted heads over many things , and then when he started on on-site septic - I found he was a complete IDIOT on systems and how they worked or were installed . Seems my required Pipe Layers certificate for my on-site covered more on plumbing drain systems than he knew .  

We installed a new water heater a few years back.
I had to break off a tab to turn it up.
It still doesn’t get hot enough to suit me.
Always hotter after a recovery than if it’s been sitting a while. Doesn’t seem to maintain heat.
Bought at Homedepot.
I wonder if our faucets are part of the problem?

Just installed a new Rheem at the farm and I swear, I can pee hotter....
