It keeps the hot water coming out of the hot taps in the house at a maximum, below scalding, temperature. That is the reason it is law to have it fitted even to old hot water systems.
@@cameltoehunter It's the law now, here in Ontario, Canada. We have a 4 year old house and I only get luke warm water coming out of the taps. So, now I have to make a decision. New mixing valve or complete removal of the stupid thing. I think I'm going with Door number 2.
Because it’s set at about 50 degrees Celcius and you can’t go higher because of the temper valve, to stop people burning themselves, but most people would like the temperature to be higher
I bought a new townhome mixing valve under one of the vanities in the main bathroom. The mixing valve is a zurn. The water is lukewarm at best. Who ever installed it wore the top off the mixing valve adjustment screw, so I could not adjust it. I bought a brand new one and a plumber told me to put it on backward, H to Cold C to Hot and it would bypass the mixing valve. Well I got zero warm water now. I turned it around and adjusted it to the far left and again I have lukewarm water. Not even hot enough to take a bath. I turned it all the way other direction and it is cold. I have to take a pool noodle and run it from the sink hot tap side with the soaking tub faucet on to fill up the damn tub now so my wife can take a warm bath. Can someone tell me how to bypass this POS! What amazes me is every other faucet in the house will scald you if you turn it to hot? This makes no sense. Even my kids bath tub and shower will scald you but not the parents tub?
