The water turns cold in my tub after tub is about 4'' full.
This is in new construction. We checked the water heater thoroughly, even changed to a new one. Same problem. Now I think it's got to be the faucet. Brand new Grohe Roman tub faucet with sprayer. I turn on to fill up tub and water is so hot it scalds me. It's a 45 gallon tub. With approximately 4" in the tub, the water turns cool. Can it be that something gets warm in the faucet and changes the mix of hot and cold water? Or could it have been installed imcorrectly? This is a one handle faucet. I have pictures of my tub and the actual faucet. Please email me if you would like me to send them. Thank you, Leila

Hot on left. Cold on right. Some single handle faucets have bleed-over where both hot and cold enter mixing valve each time handle is turned on, even when faucet calls for just cold or just hot. Otherwise maybe a do-it-yourself plumber got pipes backwards... or maybe the tub used to be on other side of wall, and tub was moved during remodeling but pipes were not changed.
To fix problem: First of all, turn off shower faucet. Turn on Hot at sink and put ear against shower faucet listening for sound of water flowing through the mixing valve. If mixing valve is working fine, you need to open wall and investigate more. For example if you have access door, reach in and feel which pipe is hot. Pipes might need to be reversed if problem comes up in home inspection, otherwise the problem will not harm anything.
When you filled the water heater did you get all the air out of lines and water flowing before you turned power onto heater. It sound's like the bottom element on the heater is not working. That is if it's the same throughout the house hot then get's cold.
Check the power to the lower element and thermostat.
hot water supply is probably turned off. Is it a rental or did you buy the place? Does it have a crawl space or a basement? Where is your water heater? Start at the water heater and trace the line to the shower. There may be a valve in between that has been shut off. Good luck.
your problem can be fixed by running a loop in the plumbing. If you hired a professional in the first place it would already be done. basically the water pressure isn't enough, i bet your faucet is on the second or third floor, or even just THAT far from the water heater.
When you installed the new tub faucet you probably turned off the water to that faucet of even the whole house. IF IT IS AN OLDER HOUSE, TURNING THE WATER OFF AND BACK ON CAN LOOSEN SOME DEBRIS IN THE WATER LINES THAT CAN FIND THEIR WAY TO YOUR NEW FAUCET. If there is a screen at the end of the water outlet it can be clogged with gunk. Uncrew the screen on the water outlet and clean. You may also want to flush out the hot and cold outlets by turning the water off, removing the cartigages and slowly let water flush them out. Then reassemble. Also when you have the tub handles out you can turn the hot and cold supply valves off and on a few times to loosen more debris if it exsists........Joe
