What happens here

After removing the faceplate, temporarily turn the valve to the 'on' position to verify that no water flows from the shower head, confirming the main water supply is successfully shut off. The bonnet nut, which secures the cartridge in place, can often be tightly seized. To remove it, use a specialized DIY tool: attach a 'firmko' (a flexible rubber coupling with metal hose clamps) around the bonnet nut. Tighten the hose clamps on the firmko using a screwdriver to create a secure grip. Then, insert a 2-inch ABS pipe into the firmko and use it as an extended lever. Twist the entire assembly counter-clockwise to loosen and remove the bonnet nut.

Goal: Unscrew the bonnet nut to allow for cartridge removal.

Tools and materials

  • 2-inch ABS Pipe — Providing extended leverage to loosen the bonnet nut
  • Firmko — Creating a strong grip on the bonnet nut
  • Screwdriver — Tightening the hose clamps on the firmko

What they say

Hide

Show that off, and that's off too. Turn this full on. We've got nothing coming out. So sometimes these bought it nuts on these Delta monitor valves are really hard to get off. What we're doing here is just taking a firm coat. We're gonna stick that band right there, right around the night. And grab a piece of 2 inch ABS pipe, get that tightened up. Just twist counterclockwise. And that came out like butter. Pull out the old Knipex Cobra's.
