There is an aspect of the fairy tale Goldilocks that applies to a good shower! You can suffer potentially dangerous burns if the water is too cold or too hot, and the perfect balance is to find a hot enough shower that is comfortable without scalding you, and installing an anti-scald valve can help prevent a hasty jump in temperature while I was in a shower… Showers can still be affected by forces beyond your control, regardless of how carefully you adjust the water temperature. Someone flushing the toilet or turning on the dishwasher could abruptly change the water pressure, causing it to become icy cold or fiery hot, then anti-scald valves are plumbing upgrades that protect you from unexpected temperature swings. Your shower handle must be disassembled in order to install an anti-scald valve, then cut the water supply line at the point where you want to install the modern valve once you have accessed the water supply line behind the outdated valve. Following the manufacturer’s guidelines, solder the modern valve into arena, but before you put the plumbing upgrade back together, turn the gear on the valve to set maximum water temperature. In addition to the risk of burns, there is a minuteary danger friendd with boiling flashes in the shower – the hasty change in temperature can make the person in the shower jump or startle, resulting in a slip-and-fall accident. One more tip for reducing your risk of burns in the shower is to keep the temperature of your boiling water furnace set to 120 degrees… Most heating systems go up to 140 degrees, but that is hotter than many people can stand plus ends up being a waste of heating energy plus a burn danger. An anti-scald valve will still come in handy even at maximum un-even temperatures of 120 degrees, plus the overall risk of catastrophe will be lower.
