Shower water are just warm...
I just moved into a new house. Everything suppose to be brand new, including the shower. i have a problem with my HOT water...they are not hot...the sink water right next to the shower are extreamly hot. i dont know what the problem is...also if i take a shower over 20-25 minutes water are starting to get colder. please help me with what are my possible problems. could it be just replacing the faucet? or is it a more serious issue. i do have plastic pipes running to the shower.

Tnx for your help !

They are not hot? You mean like the molecules?

What size heater is it?
Longer then a 20 min. shower:eek:

Is it a gas or electric heater?
If it's electric I'd first check the elements.
Check what the temperture is set at on the thermastat, should not be set at more then 120 degs.
Last I would be checking the anti scald valve in the the shower control.
Some can be adjusted, some need to be pulled apart and cleaned.

The faucet I'd brand new... I think the plumber try to adjust it.... U think getting a new faucet will help get a better adjustment? If so any recommendations for one?

Brand and style will have nothing to do with water temp.

some models are adjustable, get the guy back to readjust it if he tried.
i just bought one that is adjusted to the hottest position from the factory and they have instructions on how to adjust.

The water heater is new as well... And I get extremely hot water anywhere else in the house so I don't think it's the water heater... What other options of problems this could be due?
Tnx for the quick response!

i mean the shower valve itself if adjustable.

If the shower alone does not produce hot water it may need an adjustment of the hot/cold water mixer. It adjusts the water temperature to keep it from getting too hot. This is a very simple procedure that involves removing the handle and plate beyond it and the making an adjustment, No need to shut off the house water supply. Just follow the instructions that came with the tub/shower valve. Or, have your plumber do it. If he installed the tub/shower fixture, he should have made the adjustment as part of the installation.

take the shower head off and see if the screen filter in the back of it is clogged. This will also affect the mixing of hot/cold if there is not enough flow (depending on what type of fixture it is). Happened in a rental of mine this past week.

Thank you all for the reply ! i guess i will give it a try!
so from what i understand no need for a new faucet ! just try to adjust the current one...if its the shower head or the valve.

Google your fixture and download the manual. If it is a single knob fixture it probably has an anti-scald feature that needs adjustment. close and cover the drain. Remove the medallion on the front of the handle, remove the screw under there. and pull off the handle. If you have a lever instead of a knob it will have an Allen set screw. Back it off a few turns and remove the lever. Reset the hot limit. Re-assemble.

ill give that a go as well! thank you! why you think the "hot" water got even colder after 25min...while the sink water are still very hot!

Well, assuming you have a tank type hot water heater, and not an on demand unit, you have a finite amount of hot water at your disposal. As you use up the hot water in your hot water tank, cold water enters the tank to be heated. That new water takes time to heat up, and the temperature coming out the fixture starts to drop when you start to hit the new, not yet hot, water. If your shower fixtures anti-scald device is set real low, you cannot increase the amount of hot water mixing in the valve, so your shower gets cold.
