"The Delaware Plumbing Professionals (DPP) that installed my products were Ryan and Anthony. I was very happy with the products and services provided to me. Here are things I want to express in no particular order. 1. Ryan/Anthony were on time. 2. They answered all of my questions. 3. I feel good knowing that my water hardness has decreased and the amount of chlorine in my water is less. (Artesian adds a lot of chlorine.) 4. I now get suds when I shampoo my hair. 5. My water tastes better. 6. I don't get orange rings in my toilet. 7. Ryan/Anthony are nice guys and a pleasure to talk to. 8. I was not pressured into buying anything. 9. I am definitely going to call DPP the next time I have a plumbing issue/need. 10. I will recommend DPP to my friends and family. Thank you, Alfred (Chad) Alspach"

"My hot water heater was replaced the same day. Old hot water heater was installed in 2000 so it didn't owe us anything. Done Right Today was courteous, professional, and offered a reasonable price. My wife and I were very pleased with their work. David and Jan Magaha"

"They demonstrated excellence in understanding the need, responsiveness, communicating every action to be taken ahead of time, calculating a fair estimate, explaining options for replacement, timeliness, and exceeding all expectations. Our technician, Zach Womer was outstanding in diagnosing the issues with my water heater, recommending replacements by listing the strengths and limitations of each choice, explaining the installation, confirming the availability of the replacement, estimating installation timing accurately, completing the job thoroughly and neatly, and most of all always staying in touch including after the services were provided. Poseidon and Zach are outstanding and deserving of customers' confidence."

"The men worked very hard...VERY . I have nothing to compare it to but it seemed that a broader auger might have boared thru the roots more efficiently.I believe it was only 2.5 inches vs the wide variety of water jet heads which you use primarily. Nomatter....I am satisfied that my drain s open. I can't comment accurately o bang for my buck as I have nothing to compare with;however I am happy to not be mucking thru the flooded basement and compliment the fellows on their determination!"

"I was nervous to check on water systems for our house and am happy I found Purfect Water Solutions. After checking through Angie's list I got an immediate response and scheduled a time to meet with Scott. He came in and tested the water, he educated us on where our water quality is now (not great) and even tested our bottled water we got from the store (which was also not great). Great financing program if you worried about $ and referral program. W/ what we pay for water this was a no brainer. John came by our house in days with the system and had it hooked up the same morning. He was very nice, punctual, respectful and knowledgeable with what he is doing. I don't usually write reviews... but we want safe water for our kids and family and Scott & John did such a great job I want to write a good review and share our experience. Water is so important everyday. Do yourself a favor and at least get your water tested so you know what your family is drinking/washing with."

Water Heaters FAQs, answered by experts

Unusual noises, lack of hot water supply, efficiency loss, and visible leaks are signs of necessary replacement beyond mere repair.

Examples include gas stoves, ovens, and water heaters. Confirm with your provider for specific items.

The good news is that most home warranty plans cover hot water heaters, regardless of whether you have a tank or a tankless model. Your hot water heater should be covered by your home warranty because it's considered an essential home appliance.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.
