1/2" Exposed Thermostatic 32 Point Cartridge 88.30.300

Product 88.30.300 or 18.30.300

COMPATIBILITY

Determining Whether You Need the 20-Point or 32-Point Version

Remove the Temperature Control Handle and count the number of ridges on the brass tip of the thermostatic cartridge. If your existing cartridge has 20 ridges, order the 20-Point Version. If your existing cartridge has 32 ridges, order the 32-Point Version.

How to Remove Temperature Control Handle

1. Turn the temperature control handle so the set screw hole points upward.
2. Use an Allen key to remove the set screw. (Make sure the set screw does not fall down the shower drain.)
3. Position your feet so you have a steady stance. Pull the center of the temperature control handle toward you using both hands. (Do not pull on the ceramic lever, because you can break it apart from the metal portion of the handle assembly.)
4. If the temperature control handle does not pull off, spray Liquid Wrench or WD40 three to four times into the set screw hole. Wait between each spray so the lubricant seeps into the set screw hole.
5. Wait 10 minutes, so the lubricant can soak in between the parts.
6. Position your feet so you have a steady stance. Pull the center of the temperature control handle toward you using both hands.

If the existing thermostatic cartridge has 20 points on the brass tip, click the link below to purchase the 20 point version:

This thermostatic cartridge is part of a mixing valve that mixes hot and cold water to achieve a desired water temperature. It prevents very hot water from scalding your skin.
