I’m not sure Home Improvement is the correct sub for this, but I’m looking to replace my dual flush actuators with metal ones instead of these chromes plastic ones that corroded due to the bleach fumes from using bleach bricks in the tanks. I’ve stopped using them, but I still need to replace the actuators or buttons and I want something more robust.
Edit: went ahead and ordered duplicate replacements.
I don't have a product you are looking for but advice to find a replacement.
Measure the length of the sticks from button mechanism inside the tank.
Measure the height of the button from lid to the sticks.
Measure the hole diameter when you take these out. If your lid is unusually thick, measure the thinkness of the hole.
Look in the tanks. If there is a gap of the internal buttons more than a few millimeters, measure that too.
All of these measurements will make find a replacement easier. A lot of the replacement buttons have really short sticks. Watch out for that.
