Tip & How-To about Plumbing

Adjusting the temperature setting on a Delta single handle faucet 13/14 series.

Delta single handle Tub & Shower faucet temperature control adjustment.

Step 1 - Remove handle to gain access to rotational limit stop. Once handle is off there ia a plastic limit stop disc. Remember where it is to start with. Metal handles require a 1/8" allen wrench to remove handle. Plastic handles require removal of cap to access screw to remove with phillip's head screw driver.

Step-2- To adjust the temperature of the water coming out of the valve, pull the disc back to a position where it is possible to remove the Rotational Limit Stop and readjust the teeth to desired position to acheive temperature. Once moved reinsert it into place to test water

Step-3- Clock wise will decrease the temperature and counter clockwise will increase the outlet temperature to a hotter setting. Temperature setting per tooth (notch) could result in 4 to 16 degree's based on inlet water conditions.

Check water temperatures to make sure it is at a safe temperature to avoid scalding. Safe operating temperatures range around 120 degree's. Some may have to be adjusted based on season's.
Winter season's when it is cold outside you may have to turn temperature up due to water coming into house will be colder than it would be in the summer.

Wateris not hot enough, need to know how to adjust scauldgard on faucetto getmore hot water, and less cold.


Assuming that you have sufficient hot water, you need to adjust the Scald-Guard valve. It's usually quite easy to do. The intent is to limit the amount of hot water that can be fed to to shower head or tub spout. On the 1300/1400 series faucents there is a disk behind the faucet knob/lever called the rotational limit stop. Remove the knob/lever, either by popping the cover off the knob and removing the screw with a Philips head screw driver, or removing the handle with an allen wrench. Next adjust the rotational limit stop disk clockwise to increase the limit on hot water flow. Delta claims each tooth you click past clockwise will increase the maximum water temperature by 6 degrees F.

Delta has a great FAQ on their web site. As of Jan 30, 2011, this link is valid:

If the rotational limit stop disk is already turned to the maximum point (clockwise), then you may have a hot water flow problem (either with the cartridge or to or in the manifold). The cartridges require a little more know-how to replace. You'll need to shut off the main water valve prior to removing the old cartridge. There are a couple of places that detail how to replace and/or service the cartridges, including a short video on youtube. I can post more details on this if you find you need to replace the cartridge.

We have a home that is 3 years old. We never used the 3rd bathroom shower until today. We have a Moen single knobe shower/bath valve. To get water from the faucet you pull the knob out. To adjust the water temp - Left for hot and right for cold. When rotated to the left for hot the water shuts off. When rotated to the right we get only cold water. Could the valve be installed wrong or could the cartridge be installed wrong? Kevin


Remove handle to gain acess to the temperature limit stop. Remove handle and pull out handle adapter kit and next there is a dail that can be adjusted to control the water to balance the temp. It could have been installed wrong, pay attention to where it is now and pull it back to it disengages out of the stem and move it counter clockwise a little and reinstall. Put handle on and test water for correct movement.

Go to link below for a part's diagram if needed.

I have a delta shower faucet that I just repaired and wonder how to adjust a thing called the rotational limit stop?It says see instructional sheet which I don't have.


There is a round ring with teeth. This can be rotated clockwise or counter clockwise to adjust the tempered water temp. This step will have to be repeted until you get the temp that you want. Should be no more that 105 degrees max.
