Why would the shower water only get really hot when the cold water is turned on in the tub?
Because someone has connected the hot water line to the cold service. They are reversed. Answer 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.

Answer The mixing valve is messed up...It's easier to fix than figure out.
Answer Do you have hot water at other fixtures in the house? If not you have a water heater problem. If yes the Shower valve needs to be rebuilt if it is a… bressure balanced faucet the concentration should be on the pressure balancing spool area of the faucet.
I have just the opposite problem.. I'm only getting very hot water coming out of shower head. What I've been reading is it's most likely the mixing valve/anti-sca…lding valve. As long as you are getting normal water temps and pressures from your sinks then you should either replace or repair the showers mixing valve. The best I can explain the way the mixing valve works is it uses the pressure of both the cold and hot water to limit the amount of either hot or cold water that it will let pass through it. If the valves don't slide properly do to dirt or any thing that may build up on the valve or valve seats then the mixer valve can't do it's job properly. Hope this helps Ken
your hot water supply line is stopped up.it could be anywhere more than likely at the shower valve remove valve inspect then proceed towards sink and hot water tank
Blcoked piping or defecive valve
Diverter not functioning and depending on which type you have would determine the type of repair or replacement
The answer could be a couple of things, Firstly check that the water heater is switched on at the electrical point. If it is switched on, check to see that, the pipes fo…r the hot line are not blocked, depending whether you have a mixer or a tap installed will also depend on how to fix, check, clear anything blocking by the washer or o ring.
What would cause there to be no hot water in only one bathroom sink tub and shower - Everything comes out cold only?
Either the stopcocks feeding these lines are switched off or the lines could be blocked. Another thing to check is that the headparts are not jammed with debris.
Why would you suddenly get only cold water in your bathroom sink but get hot and cold in the shower?
Depending on whether this is a tap or a mixer. Will depend on the answer. If it is a tap, the washer could be stuck, preventing the water from coming out or it may… be jammed with some form of debris. If its a mixer, the o rings inside could have slipped out of place preventing the mixing of the water properly or it may we jammed with some form of debris. Another option to look at is if the tap or pipe feeding the mixer has its own individual stop cock, it may be either closed or jammed with some form of debris.
When i turn the hot water in the tub on low and introduce a little cold to it it is finebut if i turn the hot on more forceful it turns cold on meSame when i use the shower diverter maybe any ideas?
We had the same problem and all my mom did was turn on the hot water some way shower or sink and wait 10 minutes and bang the heater. If that doesn't work then try calling you…r service person.
You may have temperature-adjustable fixtures installed in that bath. For example, the Delta Monitor series lets you set a maximum hot water limit, to prevent scalding. Try loo…king up your faucet/showerhead model online to see if they are adjustable in this way.
The temperature setting on your hot water heater may be set too high. There is an adjustment behind the panel.
First make sure that the hot and cold supply lines (the plumbing) aren't backwards (hot should be on the left as you are facing the faucet) or that someone accidentally ran tw…o hot lines. For the problem to be in the faucet itself you would have to have a single handle faucet. If this is the case the control valve is broken and should be replaced. Three handle Left= Hot Water Flow. Right= Cold Water Flow Center= Controls whether the water comes out the shower head or tub faucet. Two handle Left= Hot Water Flow Right= Cold Water Flow (Diverter Valve is elsewhere if it's a tub/shower) Single handle One handle controls both water pressure and temperature
Most people much prefer showering with warm water.
How can you stop water leaking through the shower head when both cold and hot water are on but you want the water coming in through the tub faucet and not through the shower head?
You need to replace the valve that redirects water from the tub's faucet to the shower head .
On single handle shower valves, designed to let cold water first and turn handle farther to mix hot water to desired setting. If hot water turned on first, possibility of gett…ing scalded. If seperate hot/cold handles for shower, shower valve needs work.
Why would no water come out of any hot water faucet but if I turn on the cold water in the tub then the sink with the hot water knob on will run cold water I am thinking the pipes can't be frozen if w?
You probably have a blocked or frozen pipe into the H/W tank.
