  • Tips & Tricks

  • What to Do if You Have No Water Pressure
    If you're losing hot water pressure in your house don't just assume you need a new water heater. A bad water heater installation can cause the hot water outlet on your water heater to corrode and clog up, restricting water flow. You don't necessarily have to replace your water heater. Removing the infected piping on the top of your water heater should solve this problem. Whether you live in Oak Creek or Greenfield, water heater installations and repairs should be performed by a professional from Knight Plumbing, Inc.
  • How to Increase Your Water Pressure
    One of the most common complaints people have with their residential plumbing systems is a lack of water pressure. If you are experiencing this problem at one or more of your plumbing fixtures, don't just assume it's the pipes. There are a variety of simple problems you can check before calling a plumber. Take the screen off of the spout of the faucet and clean it out. Remove your showerheads replace them or clean them. Rust and calcium build up inside these parts giving you the impression your water pressure isn't what it should be. If you are experiencing plumbing issues, contact the plumbers Oak Creek and surrounding cities rely on for on-time, professional plumbing services.

    It's nice to have hot water in your house when you want it. One day, that hot water is not going to come out of the tap and you may have to repair or replace it. There are some things you can do to push this day off far into the future. The most important of these things is to drain your water heater every year, especially if it's more than five years old. The second most important thing is to remove and check the anode rod inside the water heater. By performing these two maintenance steps on your water heater, you will certainly extend the life of your water heater by 5 to 10 years. Contact the South Milwaukee area plumbers today for professional water heater maintenance.
  • How to Maintain Your Disposal
    Keep your garbage disposal clean and healthy by remembering these tips. Run a strong flow of cold water through the disposal whenever it's in use, and then for at least 20 seconds after turning it off. To freshen your disposal, periodically grind a half lemon or lime while running cold water. To keep the blades sharp, periodically grind ice cubes while running cold water. Never put fibrous foods like celery, corn husks, and potato or onion skins in the disposal. The disposer might handle it, but your drain may not. Never use liquid drain opener in a clogged disposer drain, and NEVER stick your hand down there! Use tongs or pliers to remove obstructions. For garbage disposal maintenance that requires a professional Greenfield plumber, contact Knight Plumbing, Inc. today.
  • Got Smells? Check for Block Sewer Gas Entries!
    Occasionally homeowners complain about a musty smell coming from their bathrooms or basements. This musty smell could be sewer gas coming from various sources. Most commonly from floor drains. In your basement, you most likely have a drain on the floor. Sometimes these get covered up or otherwise hidden from view for various reasons. After a while, the water will evaporate and it needs to be refilled with water. It's the water in the trap that keeps the sewer gases at bay. Also, if your toilet rocks or moves around, a damaged wax ring seal may not leak but allow sewer gases to enter your bathroom. The wax ring will need to be replaced. If you are experiencing any of the above issues, contact the plumbers Oak Creek and surrounding areas rely on for musty odor control and other various plumbing issues.
