FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for. Just going in circles with them and FedEX. If they shipped after 14 days it would be 22 days from that point, 32 days from the date of order if they shipped it that day.

"I got six estimates for replacement of my 12-year-old water heater. I went with Advanced Water Systems of Coastal NC-VA. I’m extremely happy with the purchase and installation of my new water heater. Advanced Water Systems of Coastal NC-VA impressed me at every step of the process. They provided a fair estimate, professional communication and installation, answered all my questions during the process, and cleaned up after they were done. The installation team installed a new gas shut off valve and an expansion tank, in addition to the water heater, and didn’t add on extra charges like some companies. They also insulated the pipes. I’m thankful that everything is now up to code. The plumber explained the purpose of the expansion tank, other companies didn’t even mention one. Both of the people doing the install were highly knowledgeable and efficient. I highly recommend Advanced Water Systems of Coastal NC-VA."

Water Heaters questions, answered by experts

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

When investing in a new furnace, it’s smart to do a home energy audit. That will give you a list of any projects that would help with efficiency, such as sealing or replacing windows and insulating the attic. You can also take this time to install a smart thermostat if you don’t already have one to make heating your home a breeze.

Signs that your water heater may explode include rust-colored water coming from hot water taps, the smell of sulfur or rotten eggs coming from the water, shaking or rumbling in the tank, and a leaky temperature and pressure valve. If the water heater feels excessively hot to the touch, it could also indicate the prospect of an explosion. If you suspect your water heater might explode, call a pro immediately to address the problem.

Tank-style hot water heaters need replacing about every six to 15 years, while a tankless model can last 20 years or more. Over time, water heaters fill up with sediment that can start causing issues. If your unit is ten years old, start thinking about a possible replacement. Flushing your tank-style water heater annually and having routine maintenance done can increase the life span of the unit.

You don’t have to replace expansion tanks at the same time as your hot water heater. You may be able to go six to 12 years or more before needing to replace your expansion tank. At $150 to $450, hot water heater expansion tanks are usually much more affordable than the cost of hot water tanks themselves, which average about $1,190.
