Geberit UP170 Replacement Outlet Valve

Is this the right valve for your Geberit? Geberit cisterns look similar from the outside, so you must perform the Sticker Test to ensure compatibility. Look inside your cistern tank for these specific codes:

• Model Codes: 224.383.00.1 or 110.70X.00.1.

• The Configuration: This valve fits the UP170 Twinline, whether it is Mechanical (rods), Pneumatic (hoses), or Electronic.

• Pneumatic Check: If your system uses hoses, they should be Green and Clear.

• Don’t Get Confused: This valve is often mistaken for the Kappa (240.638.00.1) because they share the same pneumatic lifter. Check your cistern model number carefully!

Genuine Geberit Engineering The Geberit UP170 is a robust system, but over time, the internal seals and plastic housing can degrade. Replacing the outlet valve is the most effective way to solve two common bathroom headaches:

1. The “Ghost Flush”: If water continues to run into the pan after the flush, the valve is failing to seal.

2. Weak Flush: If the toilet isn’t flushing as powerfully as it used to, the valve is likely not lifting to its full height.

Technical Partner Parts:

• For Pneumatic Systems: We highly recommend replacing the Pneumatic Lifter (240.574.00.1) and the Hose Pack (240.575.00.1) at the same time to ensure the air pressure triggers the flush perfectly.

• The Inlet Valve: If your tank is filling too slowly or overfilling (spilling into the pan through the overflow), you need the Geberit 222.013.00.5 Inlet Valve with Flexi Hose.

• Q: My old valve doesn’t look exactly like the photo. Will it work?

  • A: Geberit occasionally updates the color or plastic mold of their valves, but as long as your cistern sticker matches the codes listed above, this genuine replacement is 100% compatible.

• Q: Should I replace the hoses too?

  • A: Yes. Over years of use, the clear and green hoses can become brittle or develop microscopic cracks, leading to a loss of air pressure. The 240.575.00.1 Hose Pack is a cheap insurance policy for a perfect flush.

• Q: Do I need a plumber to install this?

  • A: Geberit valves are designed to be serviced through the flush plate hole. If you are handy with DIY, it is a straightforward “clip out, clip in” process.
