FAQ
Q: What's the difference between this and just the cartridge alone?
A: This kit includes both the cartridge AND the mixer cap. The mixer cap can wear separately and cause temperature control issues even with a new cartridge. Replacing both ensures a complete fix.
Q: How long does a Kohler cartridge typically last?
A: 5-10 years depending on water quality. Hard water or high chlorine content can reduce lifespan to 3-5 years. If your home is 10+ years old and the cartridge has never been replaced, it's due.
Q: Do I need plumber's grease for installation?
A: The cartridge comes pre-lubricated. However, applying a thin coat of silicone plumber's grease to the O-rings before installation ensures smooth insertion and prevents seal damage.
Frequently Asked Questions
Q: What exactly comes in this combo kit?
A: You get three items: the GP76851 pressure balancing unit cartridge, the GP500520 cartridge, and the GP77759 mixer balance cap — everything for a complete Rite-Temp rebuild.
Q: Do I need all three parts, or can I buy just the cartridge?
A: If you're experiencing temperature fluctuations AND handle stiffness/leaking, replacing all three at once ensures a complete fix. For cartridge-only issues, we also sell the GP500520 individually.
Q: How do I know which Rite-Temp model I have?
A: Remove the handle and trim plate — look for "Rite-Temp" branding or the K-304/K-8300 valve body. If you see a single brass stem with a plastic body, this kit fits.
Q: Will this stop my shower from going cold when the toilet flushes?
A: Yes! Temperature fluctuations during other water use is the #1 symptom of a failing pressure balancing unit — the core function this kit restores.
Q: What tools do I need?
A: Phillips screwdriver, adjustable wrench, needle-nose pliers, and optionally a cartridge puller tool. Most DIYers have everything they need.
