Why is there hot water coming out of my cold tap?
Ventilation Ducts
During the colder months, ventilation ducts can be warm to the touch due to the warm air traveling through them. If the cold-water pipes are touching the ventilation ducts, the water within them can begin to warm up. This can become a concern further into winter as the heating system is used more.
Why do I have hot water in one bathroom but not the other?
What’s most likely happening is a problem with the shower’s mixing valve. The mixing valve is a control valve that creates the balance in the flow of water from the hot water line and the cold water line and blends the two together for your desired shower temperature.
Why am I getting hot water everywhere but the kitchen sink?
There could be a few reasons why your kitchen sink is not getting hot water. It could be caused by a failure in the faucet cartridge, an issue with the water heater, or a blockage in the faucet. Examine each possible issue until you find the one that is causing the problem with your kitchen sink.
Why do I only have hot water in part of the house?
A hot-water deficiency only at one faucet may be because of the temperature-limiting function of the faucet. If you don’t see an adjustment on the outside of the handle, you’ll find it just underneath when you remove the handle.
How do you get rid of an airlock in a hot water system?
The first way to clear an airlock, involves attaching a hose pipe to the hot and cold taps at a sink. Then, turn the cold tap on so that the water flows through the hose pipe and into the hot water tap. This flow of cold water into the hot water tap should clear the airlock.
Where is the mixing valve located?
This is typically attached directly to the shower, or under the sink, to control the water temperature and provide anti-scald protection. There is a specialty type of emergency thermostatic mixing valve, which is specifically designed to provide tepid water for emergency eyewash or shower drench applications.

What does an anti-scald valve look like?
They look similar to ordinary shower and tub valves and are equipped with a special diaphragm or piston mechanism that immediately balances the pressure of the hot- and cold-water inputs, limiting one or the other to keep the temperature within a range of several degrees.
Why am I getting hot water everywhere but the bathtub?
Old pipes sometimes get clogged with mineral deposits due to chemical imbalances in the water. This can block hot water from reaching the bathtub faucet, even though the sink’s hot water faucet is working fine. A clogged pipe may be the culprit if you replace the faucet and still have no hot water.
Where is my shower mixing valve located?
You can see the trim on the shower faucet, but the actual valve is behind the wall and is permanently connected to the plumbing. To replace it, you need an access panel through the shower wall, and if it isn’t designed into your bathroom, you’ll have to cut one.
Why is there no hot water in my shower or sink?
Check Other Faucets in the House
If the temperature of the hot water cools quickly, you may have a burner problem with your water tank. If there is no hot water coming out at all, it could be a faulty dip tube. Now, if all the other faucets have running hot water, then the issue may lie in your shower components.
Why is there only cold water coming out of my shower?
Check the other hot water faucets in the home.
It may be possible that one of the heating elements in the unit is malfunctioning, which causes the appliance to make an insufficient amount of hot water. If all of your faucets are dispensing cold water, the dip tube in the water heater tank may have deteriorated.
Why is my hot water not working but my cold water is?
If you have good water flow (“pressure”) at hot water faucets, but it’s cold, then the water supply piping is not blocked and the problem is in the water heater itself, or in a mixing valve.
Will an airlock clear itself?
An airlock will not clear itself. It acts like a restriction in the pipes and the only way to clear it is by blasting water at high pressure through it. Water pipes are hardly ever straight and that is why an airlock will not clear on its own, as it occupies the highest point of the pipes.
How do I know if my water heater element is bad?
Signs of a Bad Water Heater Element
- Lukewarm water.
- Small amount of hot water.
- No hot water.
- Hot water runs out faster than usual.
- Water heater’s circuit breaker constantly trips.
Do hot and cold water come from different pipes?
Just before connecting with the water heater, however, your main line splits into two different pipe paths. These paths are called the hot and cold service lines (which creates your hot and cold water plumbing system).
Is hot water pipe on left or right?
Cold water should always be on the right side of the faucet and hot on the left. This is an industry standard throughout North America, and applies to single lever as well as dual faucets.
Why are both pipes on my water heater hot?
A: It is normal for the incoming cold water pipe to get a little warm due to convection – that is, hot water rising in the tank. Also copper piping is a good conductor of heat. Many modern water heaters have built-in heat traps to limit the migration of hot water.
