Garbage disposals are an integral part of today's kitchen. We offer service on all brands and carry the Insinkerator on our trucks for installation or replacement. We can also install any brand that you supply. To maintain your disposal:

  • Put ice cubes in the disposal to sharpen the blades between uses
  • Grind up citrus fruits in disposal for a fresh citrus smell

Instead of guessing where the pipe is or where the leak is coming from and ripping up your walls, digging up your yard, or jack hammering your floors/driveways/patios, R.K. Knight Plumbing can electronically locate and trace most pipes. It doesn’t matter if they are in the wall or in the ground, we can find them. By doing this we will be able to fix your leaky pipe with as little harm to your home, yard, floor, driveway or patio as possible. Thus, not only saving you time and money, but also the worries of how much damage is going to be caused to your home when trying to guess where the pipe is.


Thermal expansion is the term used to describe the circumstance of water expanding in volume as it is heated. The installation of a thermal expansion tank in the cold water line of the water heater can protect the system from the damaging effects of thermal expansion and increased pressure. R.K. Knight Plumbing can install and service all bands, sizes and models of expansion tanks for your home or business. Thermal Expansion and Your Water Heater.


A faucet should operate smoothly and shut 100% of the water off with minimal effort. If your faucet requires more strength to turn it off or if it leaks (even a little) it's time to have it looked at by a professional. We offer service on all brands of faucets and carry Wolverine Brass and Premier Faucets on our trucks for installation or replacement. We can also install any brand of faucet that you prefer or provide. Wolverine Brass and Premier Faucets are only available to the professional plumber. They are available in a multitude of styles and finishes. Ceramic Disc technology allows for effortless operation and are backed with a 100 year manufactures' warranty against leaks.


RK KnightDid you know that for a fraction of the cost of bottled water you can have a clean fresh glass of quality filtered water from any faucet in your home? If each person in family of 4 replaced drinking one bottle of water a day with a glass from the tap, there would be 1,460 less plastic bottles going to landfills and the family would save almost $3,000 a year from buying bottled water.

We offer a variety of solutions from point of use filters such as inline ice maker and refrigerator dispensers to whole house filtration systems. Whether you want to filter out bad taste, foul odor, heavy minerals or other contaminants we have a solution for you.

Did you know that shut off valves should be a durable style to allow for repeated use to allow for water filter replacement? Did you know some appliance installers use an inferior self piecing saddle tap type valve that is prone to leaking and could cause severe property damage when the leaks occur?

R.K. Knight Plumbing doesn't use this type of valve, instead we will install a full sized 1/4 turn solid brass body shut off vale to allow maximum flow to the appliance and ensure years of trouble free service. We will professionally install a water line to your refrigerator.

Water lines should be installed to allow for the refrigerator to be pulled out for proper cleaning. So we use only 1/4 soft drawn copper tubing, no plastic tubing so you don't have to worry about a leak.


RK KnightThink about all the wasted water that runs down the drain while you are waiting for hot water so you can shower, shave, wash your face or do dishes. How many gallons of cold water are wasted while the water runs waiting for hot water to be delivered to the faucet? We can calculate the monetary cost of the water waste but what about the impact on our environment?

The good news is that through modern technology advances in the plumbing field we are able to deliver hot water to any faucet in your home immediately. It may sound too good to be true, but it's not.

We offer products like:

  • Instantaneous hot water dispensers. These dispensers mount to your kitchen sink and can instantly deliver 190 degree water for an instant cup of hot soup, coffee or tea.
  • Comfort service hot water re-circulation system from Grundfos. With the installation of a pump at your water heater and inconspicuous bypass valves at fixtures furthest from the water heater can deliver hot water in seconds, not minutes.

Hot water recirculation means a continuous flow of hot water in the hot water supply line of your home. Without a "recirc" system, unused hot water in the line cools and must be evacuated before hot water from your water heater can reach the desired faucet. As a result, gallons of water are wasted - and so is your time.
