A blocked or misadjusted cartridge can cause low flow and low temperatures. Moen single-handled shower faucets rely on an internal cartridge to regulate water flow and temperature. When hot water isn't flowing from your shower but the hot water system in your house is otherwise functioning normally, there could be something blocking the cartridge. It's also possible that the cartridge is installed incorrectly or that the temperature limiter needs adjustment. You may need to remove the cartridge to make repairs, and that may require a special tool. Preliminaries Before you begin disassembling the shower valve, it's wise to ensure that you don't have a problem with the hot water heater. Run the hot water in the sink and measure the temperature. It should be 120 degrees Fahrenheit or higher. Once you're sure there's a problem with just the shower valve, you need to find a way to turn off the water. There may be a dedicated shutoff valve for the bathroom, but in most houses, you have to turn off the main water valve.

It's usually located by the water meter or the water heater. The Temperature Limiter Many Moen faucets have a temperature limiter installed on the valve stem that prevents the user from turning the handle too far to the hot side. Grow Lights Indoor Plants WalmartYou access this limiter by removing the handle, which you can do after unscrewing a retaining screw with a Phillips screwdriver or hex wrench.

You usually have to rotate the top piece clockwise to increase the temperature.

Removing the Cartridge If the limiter isn't at fault -- some faucets don't even have one -- the cartridge may be blocked or installed upside-down, and repair involves removing it. The manufacturer intends this to be an easy job: you pull a retaining clip and pull out the cartridge with pliers. It's seldom so simple, however, because the rubber O-rings bind with the metal sleeve of the faucet body. To get it out, you may need a faucet-puller, which is a tool that Moen makes for this purpose. It screws into the stem and lodges against the housing when you tighten it, breaking the cartridge free. Repairing or Replacing the Cartridge It's important to note the orientation of the cartridge before you pull it out. You may be able to restore hot water flow by rotating it 180 degrees and reinstalling it. If not, it's best to replace it. The internal mechanism can get clogged with mineral deposits and other debris, and it isn't easy to clean. Moen makes a number of standard cartridges, and you can find the one for your faucet by looking up the faucet model on the Moen website.

When you install it, be sure it goes in far enough for the retaining clip to fully seat. 114 posts, read 164,811 times My weekend accomplishment, to share with others...

I had one go bad in my shower. Ultimately I dug around online and found some info about fixing it. Found the tool, found the cartridge, was able to fix it that night. Now that I know, I'll be able to repeat it no problem if I ever have to. But it's still a pain! Not sure you'll ever know the why it went bad. These things are prone to failure it seems to me. Best way to prevent is to buy some other brand faucet. 14,533 posts, read 20,877,240 times 1 posts, read 8,466 times need help-no hot water 8,921 posts, read 33,173,370 times Originally Posted by greg goodin Did you turn the hot water shut off back on?- believe me, it happens!
