It had been dripping about 5 drops per minute for years. And when I turned on hot water in a nearby faucet, the dripping became much worse. This had been puzzling me for a long time. Some of the YouTube videos suggest the rubber O-rings are bad so I bought some and replaced them all but the dripping issue did not get any improvement. I then replaced this pressure balancing unit cartridge and it completely fixed the dripping issue. When I carefully examined the old cartridge, I noticed that a small gap between the left and right parts can move slightly if I press them together. Kohler uses 4 rivets to join the left and right parts, and during the long run, they become loose eventually and causes leaking. I believe this is a design flaw in Kohler. I guess Kohler just wants to save a few cents by using rivets instead of screws, and this is causing slow dripping issue on old shower valves world widely.BTW, this cartridge is pressure balancing unit (PBU). This is NOT a temperature balancing unit. It only compensates the water flow rate in the left and right side water inlets based on the pressure in them are changed, not based on the temperature in them are changed. Kohler shower valve does have the temperature limit stop, but it's on the mixer cap unit, not on this PBU cartridge.So I suggest if your shower valve has the same slow dripping issue, replace this PBU first. If the issue is not resolved, then replace the mixer cap. ### ⭐⭐⭐⭐⭐ Excellent *by A***. on Reviewed in Canada on 3 June 2021* Perfect fit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/334514687-ifjf-pressure-balancing-unit-cartridge-shower-replacement-the-model-gp500520](https://www.desertcart.tn/products/334514687-ifjf-pressure-balancing-unit-cartridge-shower-replacement-the-model-gp500520) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-28*
