Benefits of Replacing the Cartridge
Leaking bath fillers or showers. Poor water flow. Difficulty controlling water thermostat. These are just three of the usual problems with shower valves. One of the reasons this happens is due to a broken thermostatic cartridge.

By replacing a thermostatic cartridge gone defective, you can enjoy adequate water flow from the shower head or bath tap and ease in regulating water temperature. Plus, you can save money and conserve water with a drip-free tap.

Ultra DC70T32-M Installation
DC70T32-M Ultra Valquest spare part is an easy fit thermostatic cartridge. It can regulate water temperature with precision based on a showerer’s preference. This “how-to” refers to the Ultra, Hudson Reed, and Premier dual control shower valve.

1. Turn off hot and cold water supplies.
2. Take out the decorative hot and cold indicator. Use a screwdriver to remove the centre screw.
3. Unscrew the flow handle prong. It can be done by hand or wrap it with a rug and use tongue-and-groove pliers.
4. With the prong out, there is a grub screw. Use a 4mm Allen key to unscrew it.
5. Remove the valve cover by hand. Turn it anti-clockwise to remove. Force might be needed if the cover is tight. Or you can use rubber gloves.
6. Note down the position of the stop ring. Take a picture of it, so you can return it in the same position when you reassemble the valve.
7. To remove the stop ring, take the chrome nut out. If it is tight, try using rubber gloves or a rag and large grips.
8. Slip the stop ring out.
9. Remove the brass retaining collar. You can do this by placing 2 screwdrivers in 2 of the collar’s indents and then loosen the collar. You can also use grips.
10. Remove the nylon washer.
11. Lever the faulty push-fit cartridge out. Insert a screwdriver in the small opening above and below the valve body.
12. Use silicone lubricant on the O-rings of the DC70T32-M replacement cartridge.
13. Push the cartridge in the valve unit.
14. Proceed to reassemble the valve by following, in reverse, steps 1 to 10.
