Why Go Tankless?

Rather than heating an entire tank of water 24/7, tankless water heaters only heat water when it’s needed. This green solution saves energy, money, and space since the units are only about the size of a kitchen cabinet.

Compared to standard hot water heaters, the tankless water heaters that ServiceMark installs offer several advantages, including:

  • Water heating costs that are typically 50% lower
  • Efficiency ratings that are up to 94% higher
  • Compact designed units that can be installed virtually anywhere

What Causes Water to Become Discolored?

Discolored water can be associated with a variety of different plumbing problems. Iron and magnesium buildups lead to black water. Although these minerals are not dangerous, homeowners can contact a company that specializes in water softening, such as ServiceMark, to discuss how to filter these minerals out of their water.

Can Chemical Drain Cleaners Take Care of a Clog?

Homeowners often turn to chemical drain cleaners available at retailers to remove clogs. One disadvantage to using chemical cleaners instead of contacting a plumber is that they pose a danger to children and pets because of the toxicity of the chemicals. Cleaners can also erode pipes and cause damage that will need to be addressed by a professional plumber in the future.

How Can I Find the Source of a Leak that is Not Apparent?

Leaks do not always have to occur at the site of a faucet or the visible portion of a pipe. The leak can involve the toilet, which can be determined by adding food dye to the toilet tank and observing whether the dyed water leaks into the toilet bowl within a one-hour span. Underground leaks are harder to pinpoint than those that occur at a visible site, and the assistance of a professional plumber, like those at ServiceMark, is necessary to determine the site of the leak and fix it.

What Causes Hot Water to Have a Foul Odor?

Odors that are associated with hot water are caused by a combination of magnesium, sulfur, and different kinds of bacteria. Since all of these must be present in order to cause the odor, the magnesium rod that is being used to protect pipes may be a factor. Homeowners can replace this rod in order to keep odors under control. However, killing bacteria present in the pipes can better control the odor. Let the plumbers at ServiceMark assist you with this process.

How Can Homeowners Prevent Pipes from Freezing in the Winter?

Pipes that freeze in winter often do so because they are located in unheated areas of a home, or are exposed to cold winds. Homeowners can ensure that pipes do not freeze by having a plumbing inspection and replacing insulation where necessary.
