"We awoke to a completely blocked/backed-up Kitchen Sink, with the water backing up on both sides of the sink. I called Hosack Plumbing Cooling & Heating (NOTE: It is the SAME BUSINESS as SC Hosack Plumbing & Excavating listed on Angie's), and they scheduled me for an afternoon appointment the same day. Steve actually arrived at the START of the 4-hour service window, which was REALLY nice so I didn't have to wait half the day. Steve quickly determined where the blockage was in the drain pipe, and he got it removed. It was the first-time in 35-years we had this problem with our kitchen sink, and Steve explained how over time the blockage accumulated until it finally closed off all drain flow. Steve then gave us some good maintenance information for us to do once a month to help future blockages from forming. It's well-worth the cost of a bottle of Dawn Dish Soap once a month to help make sure it doesn't happen, again, and avoid the cost for this type of service in the future. :) "

Water Heaters questions, answered by experts

An average-sized empty water heater weighs around 150 pounds. Tankless water heaters are much lighter, weighing between 10 and 50 pounds. The smaller size and added convenience come at a price, though—tankless water heaters average about twice the price of their traditional counterparts.

According to the U.S. Department of Energy, tankless water heaters are anywhere from 8% to 34% more efficient than regular water heaters. Exactly how much energy you’ll save depends on your household’s water usage. When you purchase a tankless water heater, you’ll also likely upgrade to more efficient technology than your current water heater, which can add to energy savings.

The average cost to replace a water heater is $1,325. How much your replacement heater costs depends on the type, size, and complexity of installation. Gas and electric heaters may cost a similar amount out of pocket, but one type may cost more to operate than the other, depending on the cost of utilities in your area.

If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home. 

Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.

Choosing between an electric water heater vs. a gas water heater comes down to personal preference. Overall, electric heaters are more energy efficient than their gas competitors. They’re also quieter to operate, take up less room, and don’t come with a risk of gas leaks. 

The downside is that electric water heaters cost more to operate than gas. They might also struggle to heat water fast enough for households that use large amounts of hot water. Lastly, a power outage could cause your electric water heater to stop working, whereas gas water heaters may still function.
