Because someone has connected the hot water line to the cold service. They are reversed. I'm not a plumber, so I don't know if the first answer is correct or not. However, our landlord replaced our shower fixture with one that could be adjusted so that it prevented burns. He was pretty proud of it because it was supposedly an expensive model & it was safer for kids. The plumber that installed it used the default settings, I think. But I was unhappy with it for the longest time because I could never ever ever get a HOT shower out of the thing. And I didn't want to turn the water heater up because that uses more energy & runs up the utility bill. Eventually, I got brave enough to pop the cover off the shower control handle and discovered the little safety lever to adjust the water from cooler to hotter. Everything worked fine after that.

∙ 16y agoit depends on what type of shower, but the usual mistake that is made is that the cold water supply to the shower has been taken from pipes in the bathroom such as the bath tap but they should be taken from the rising main ( direct supply).

Can hot water bleed into the cold water line through a sing handle shower body?
Yes, it can also cross through a two handled faucet. Both the hot and cold sides of the faucet must be on and the flow of water must be stopped or greatly reduced on the outlet side of the faucet. This can occur when a hose with a spray nozzle is attached to a laundry tub faucet with the faucet on and the spray nozzle off, or when a shower faucet is on but the shower spray head is off. When another cold water outlet in the system is turned on then the pressure on the cold side of the laundry tub or shower faucet in question could be lowered below the pressure on the hot side and hot water can flow into the cold water side. There are faucets which have integral check valves which prevent this from occurring. WWW.WOODBRIDGEPLUMBING.COM

How does an electric shower heat up so fast?
Electric showers only take water from the mains cold water supply. They heat the water when you turn the shower on, by passing it over a heating element inside the shower - in a similar way to how a kettle works. When you shower, you don't use up and stored hot water - so electric showers are ideal for families and households where there is a limited supply of hot water. Electric showers are always ready to use, any time of the day or night
Why do we see water droplets on the outer surface of a glass containing ice-cold water?
That is because warm air outside the glass contains moisture and that moisture condenses on cold surfaces since cold air on the glass surface cannot hold as much moisture as warm air. It is the same effect as fog on the bathroom mirror after running a hot shower.

When you take a shower, you're mixing a combination of hot and cold water to make a comfortable temperature for the shower water. A toilet draws only off the cold water system. In older or poorly designed plumbing systems, when you flush the toilet, the cold water is pulled by toilet, so the water coming through the shower is only drawing from the hot water tank.
