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.
Was this answer useful?
Thanks for the feedback!
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.
The single most likely reason would be buildup of rust or calcium particles in the valves and inlet. Many showers have a one-handle arrangement wherein the handle controls mov…ement of a ball. That ball has two very small inlet holes, roughly 3mm (1/8 inch) diameter each. If your shower has this type of arrangement (and not a newer maintenance free cartridge) you can turn off the house water supply, take apart the handle and ball device, remove and replace the springs and seats for the inlets, and clean the ball with an old toothbrush and CLR. If your water heater is very old, or if you have old iron pipes for your water supply, you are likely to experience this kind of problem more frequently.
Hot water increases the release of histamines, and makes you itchy...or itchier. If you are itchy after you get out of the hot tub, the water chemistry may not be in order. Pr…oper sanitizer levels and pH levels between 7.2-7.6 are required.
always use copper for any kind of water installation
Low is 90 degrees Fahrenheit, but because your bodytemp is 98.6, a hot tub temperature of less than 98.6 will actually take heat away from your body. 100 degrees is nice and w…arm Many hot tubs will not go higher than 104 degrees, which will feel really hot but soothing when you get in. You will feel you might need to leave the tub after 20 minutes or so. Winni
Is it a central water heater or a local point of use water heater? With the centralized system: . Hot water pipes are more susceptible to corrosion then cold water pipes, the… hot water accelerates the build up of rust. If you have galvanized piping, that can be a major source of slow water. . The hot water heater may also have problems which reduce the rate that water can get into the tank and from there on into the piping system. You might insure that the valves on the hot water heater and along the flow path are all fully opened. With a point of use system, it may be that there is a control valve that won't allow the water to flow unless it is a certain temperature. If it is taking longer to heat the water, it could slow down the flow considerably. When the hot side pressure is bad in all of the house it is going to be a problem with the hot water heater outlet usually. If it is just bad at one location especially when it is the shower and your shower is a single handle unit, it is the cartridge in the valve body. It is a very common problem with Moen valves as well. Simply replace cartridge by removing trim then cartridge and install new one. They should carry your part at home depot. You will be back in business. If it is all over the house try replacing the hot side nipple and supply line coming out of heater,that will usually take care of it. If not it could be build up in piping and you might need a repipe. http://aw-sons.com/slow-hot-water-flow-in-shower/
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
Answer The mixing valve is messed up...It's easier to fix than figure out.
In modern single piece shower controls, the system can break an o-ring or hard water can cause the cold supply line to become clogged at the smallest juncture.
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
Of course it leaks as water has to drain from the shower riser
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.
Why would the hot water side of the bath tub faucet cause the water line to vibrate when turned partially on?
If you have the old style seats and washers type shower valve, the water is trying to squeeze between the seat and the washer. If it was air, it would whistle. Water hammer…s. Usually high pressure contributes to this effect. The only way to solve this problem is to replace your shower valve with a cartridge type shower valve. Or,reduce the pressure in your house. Or do like my wife told me to do. Our pipes in the bathroom sink have been vibrating for months now. We researched everything possible. She said " try turning up the valve a little". Guess what? it worked. Do the 'KISS' method.(Keep It Simple Stupid)
Your shower pours hot water out of the faucet even when off and turned to cold with the knob Any ideas on what this could be?
You don't say whether you are referring to a single handed mixer or an individual faucet. If a mixer then the o rings inside have probably worn away and need to be replaced. I…f a single faucet then either the washer needs replacing inside the tap or the gland nut (if have one) needs to be serviced. Dont forget that in a single knob faucet, there is also an adjustment to be made for the hot water temp. that comes from the shower when turned to hot....it is a sort of dial in system remove the knob handle with a Philips screw driver and see where the settings are if too high adjust down a few clicks(notches).
The valve is not be diverting all the water. This valve may need to be replaced.
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.
