130156 Cartridge: 3/4" Exact Temp System (Prior to 2009)

This article will give step-by-step instructions on how to replace a 130156 cartridge in a multi-handle vertical spa using the 3/4" Exact Temp valve system.


  • The water supply shut off valves must be turned off- see article How to Turn Off the Water Supply to the Faucet.
  • Recommended Tools: Phillips Screwdriver, Pliers
  • The following instructions assume the handle and associated handle pieces have been removed. For additional details, visit and select the type you are repairing. The faucet guide will contain specific information on handle assemblies associated with that style of product.



  1. Use a Phillips screwdriver to unthread the screw (#1) counter-clockwise.
  2. Remove the override actuator (#2) by rotating it clockwise until it stops and then gently pull it off. Slide the spring (#3) off.
  3. Remove the temperature limit stop (#4) by pulling it off.
  4. To avoid damaging the retainer nut (#5), position pliers on the flat edges of the retaining nut (#5) and unthread it counter-clockwise to remove.
  5. To remove the cartridge (#6), use pliers on the hexagonal sides (see Image 1) and unthread it counter-clockwise approximately 12 times. Pull the cartridge (#6) out.

1. Insert the cartridge into the valve body (#7) pushing it back as far as it will go. Use pliers on the hexagonal sides of the cartridge (#6) and rotate clockwise until tight.

2. Place the retainer nut (#5) on the valve body (#7) with the flat edges away from the valve body (#7). Position pliers on the flat edges of the retainer nut (#5) and rotate clockwise until tight.

3. Position the temperature limit stop (#4, see Image 2) and push it onto the front of the assembly.

4. Before proceeding, take notice of the tab on the back of the override actuator (#2). The tab will need to be positioned to the right of the raised lip (see Image 2) on the front of the temperature limit stop (#4). To make Step 5 easier, position the screw (#1) inside the override actuator (#2).

5. While holding the spring (#3) in place and with the override actuator (#2) positioned (as explained in Step 4) over the front of the assembly, tighten the screw (#1) clockwise.


To reassemble the handle, see Shower Handle: 3/4" Exact Temp-Thermostatic Lever.

If after reassembling the handle you notice that the water temperature is over 120 degrees, you can adjust it by viewing How to Re-calibrate a 3/4" Exact Temp System.
