My taps are new. When the handle is turned full hot , the water is only tepid. I think the anti scald feature is letting too much cold water pass. Please advise

Not sure about your particular valve, but most newer shower valves have an anti-scald limiter that stops the handle from turning too far to the hot water side. Check for a ring or a pin under the handle that can be set in different positions. It will need to be moved clockwise to allow the handle to rotate farther to hot.

Hope that helps. If you have trouble finding it, try looking up a diagram for the valve model.

If some taps have really hot and others luke warm, then you might have defective mixing valve, check valve, or crossover on single handled faucet.

Crossover can also cause stacking event. Stacking could be part of puzzle.

Once crossover or check valve or mixing valve problem is solved, if you have really hot water to some taps, then turn down thermostat to avoid scalding.

taps just pass water --hot or could or both
water not hot enough is from a hot water system that is not heating the water
normally there is an inlet supply tap for the hot water system
if your system has a hot water control valve ( a valve that allows cold water into the hot water line (By law) to prevent scalding and hot water burns , that unit has a have a habit of failing and making the water colder that it is supposed to be
otherwise ,
check the elements for operation

The anti scald is just a limiter on the rotation and you can remove this, if the water still doesn't get hot enough you need to replace the cartridge

Anti Scald Valves have an adjustment under the handle (remove handle) to allow so much hot water in no matter how far handle is turned. Its possible that the adjustment is set to allow only hot water in, this of course defeats the purpose of anti-scalding. Check to see if you can adjust this back. Good Luck have a Great Day. Please give a 4 THUMBS UP if this free answer was of any help.

Behind the handle there is a dial to adjust water temp cold and hot you can remove it and replace it a 1/4 turn til you can get both cold and hot. It is a anti scald it may have been put in wrong.

Make sure the cold water line is not blocked coming to valve and is open .

Your valve has an anti-scald feature which automatically adjusts the water temp if cold water is diverted to another location, e.g., a flushed toilet, washing machine filling, etc. Most valves have an adjustment screw to allow you to set the temp. Since each manufacturer is different you'll need the manual or contact the manufacturers support. BTW, these anti-scald valves are being added to building codes in many parts of the U.S.

Remove the handle,and all the trim rings,and the cartridge cover. take a flat head screwdriver and use it to lift
up the red ring behind everything, this is the hot limit safety stop,
this just stops the handle from turning to full hot.

Once you have the red ring lifted up, notice the numbers and the pointer
on the ring, numbers are on the fixture,

O= hottest 7=cold

See what the ring pointer is set to now, and move it half, before you put this back together, just set the handle on the unit and run the water to see if its to hot or not enough. Once you have found what is the best setting, then replace all covers and trim, handle.

Your Moen valve is equiped with an anti-scald device (as part of the valve cartridge) which prevents someone from getting scalded by hot water if there's a sudden demand for cold water, i.e. a toilet flush, washing machine filling, etc. Fortunately Moen stands behind their products and will provide a new cartridge.
Contact Moen and describe your problem.

look for a scald safety screw adjustment. Remove the handle, and it is underneath. this is for safety of young children, and is factory set.
