How to fix a leaky shower faucet single handle. The cartridge is one of the most critical pieces of a shower valve (together with the seal).
This ensures that water flows securely and properly from the valve to the body of the fixture.
However, if you’ve experienced no hot water or a low flow rate when showering, it’s time to replace your Delta single handle cartridge with a new one.
The reason for this is that all components will ultimately wear down, resulting in leaks and a drop in pressure coming through during use.

Look for the cartridge in the valve if your shower faucet has only one handle and is leaking. If it turns out that the cartridge is worn, you’ll need to remove it and replace it with a new one.
If you discover that only one particular lever is leaking rather than both, you may only need to replace one washer rather than both.
Turn off the water in the shower
If you replace a shower cartridge while water is still flowing in the pipes, you risk significant plumbing problems.
Because it lacks a separate shut-off valve, replacing a shower faucet differs from replacing a sink or toilet in your home.
As a result, before attempting to install the new showerhead, you must switch off the complete water supply to your home.
The cartridge should be removed
Remove the sleeve trimmer. It is sometimes threaded on one end and does not require removal. Put it aside for now if it has a spacer.
Remove the cartridge ring from the cartridge. A cartridge ring secures the cartridge in place before attempting to remove it with a wrench. Check to see if it’s merely a hand tight situation.
A strap wrench is advised for removing the cartridge ring if it is very tight. Adjustable and normal pliers should not be used since they may harm the cartridge ring and dent the surrounding plastic.
Clean the Body of the Shower Valve
Examine the interior of your shower valve using a flashlight.
If corrosion, mineral deposits, or dirt are preventing you from using your new cartridge effectively, this may not be the problem and you should contact a plumber instead.
When the replacement cartridge is installed, the shower faucet may leak. Clean the valve body of deposits and corrosion; this may be necessary for each cartridge.
To flush pipes and clean dirt that prevents a fresh cartridge, some individuals fully open the valves.
