Emergency Plumbing? Call KP First.
Plumbing issues don’t wait until it’s convenient. They strike on weekends, holidays, and in the middle of the night.
That’s why KP Plumbing offers 24/7 emergency plumbing. No matter the time, we’ll respond quickly and get your system back under control.
We know how fast water damage can spread. The sooner we act, the more we can save—your floors, your walls, and your money.
What About Water Conditioning or Soft Water?
At KP Plumbing, we believe in giving customers the facts about water conditioners. These units are often marketed as a solution for hard water, but the truth is—they don’t soften water. If you test the hardness levels before and after the unit, you’ll find no reduction in minerals. That means scale can still build up inside tankless water heaters and appliances. Unfortunately, many homeowners only realize the difference after installation, especially if they’ve had real soft water before.
We don’t make false promises. Performance depends on many factors—like water quality, flow rate, and daily usage. No professional should claim a water conditioner will last a certain number of years without understanding those details first. At KP Plumbing, we install systems that actually solve hard water problems, and we’re upfront about what works—and what doesn’t. You deserve real results, not gimmicks.
