Good Information Makes for Better Decisions.

If plumbing were as simple as replacing a shower head or a washer, pretty much anyone could be a plumber.

Obviously, that’s not the case. In fact, plumbing is a highly complex profession that requires many years of study, training, experience, and then continuing education to stay up-to-date on the latest plumbing technologies and products.

Our purpose here is not to teach you the business, but to help you make more informed decisions when it comes to your family’s improved comfort, convenience, and safety. If you’ve come to our Resource Center today looking for something in particular but don’t see it here, send us an email. We’ll answer your question directly and add the information to our web site.

We hope you find your time here well spent.

Frequently Asked Questions

What causes water discoloration?

Discolored water can reflect more than one problem. Iron and magnesium buildups, for example, lead to black water. Although not dangerous, these and other minerals and chemicals can be eliminated with a water filtration system.

Is it a good idea to use chemical drain cleaners?

Homeowners often turn to chemical drain cleaners because they’re right where you buy all your other household cleaning products, groceries, and more. They’re easy to get to. But that doesn’t make them a good buy, especially over the long haul. They’re hazardous and also dreadful for the environment. They all contain warning labels because they’re harmful. You certainly wouldn’t ingest them because they’d kill you. They do the same thing to your plumbing system. Ask Norhio Plumbing about Bio-Clean, a safe and effective organic substitute. Bio-Clean has no warning label and is safe to be around your family and pets.

How can I find a leak that I can’t see?

If you suspect that your toilet tank is leaking, put a few drops of food dye into it and then check your bowl roughly a half hour later. If the water is tinted with the same color as the food dye, you’ve located the leak. Underground or in-wall leaks are harder to pinpoint and most likely will require the services of a professional plumber.

What causes the foul odor in hot water?

Storage tank water heaters come equipped with a magnesium anode rod that attracts magnesium, sulfur and bacteria. So if your hot water suddenly develops an unpleasant odor, the solution might be as simple as replacing the anode rod. At Norhio Plumbing, we also have ways in which we can remove the bacteria fromnyour water to prevent the problem in the first place.

Why is my faucet “clunking” when I turn it on?

Most of the time, that irritating noise is caused by a loose washer, one of the easiest fixes of all.

How can I stop or prevent unpleasant odors coming from my garbage disposal?

Step one: grind up a bunch of ice cubes in the disposal. Step two: grind up a half lemon, peel and all.

What should I not put into my garbage disposal?

Fibrous foods like lettuce, celery, potato peels, corn husks and meat bones should all be thrown out with your trash; otherwise, they can jam up and/or cause damage to the unit’s blades. Grease is another item to keep out of your garbage disposal and drains as it adheres to pipe walls and eventually will cause a clog.

What do I do if I’m losing water pressure in my sink?

First, check the emergency shutoff under your sink to make sure it’s fully open. Check your washers, too. If they’re cracked or showing signs of wear, water pressure can be reduced. Water pressure can also be affected by built-up deposits of calcium and lime.

How does a tankless water heater work?

As soon as you turn on a hot water faucet, cold water enters the system’s wall-mounted unit. There, a flow sensor detects the water and automatically ignites the burner. The water then circulates through the heat exchanger which in turn instantly heats the water. When the hot water faucet is shut off, the system shuts down until the next time there is a demand for hot water.

Do water leaks get bigger with age?

Yes! So wherever you spot a leak or signs of a leak, take quick action to get it fixed. Plus, keep in mind that the “out of sight” water leaks are usually the most destructive of all. And one great hiding place for leaking water is under your refrigerator, caused by a crack or leak in the line leading to your ice maker. To keep an eye on things, pull your refrigerator away from the wall once a month during normal cleaning. It’s also to note that the smaller the puddle (if you find one), the greater the potential for structural damage, as that could mean that water is leaking into your floor boards and beyond. While your back there, dust your refrigerator coils, too, to help prevent the appliance from freezing up.
