"Rude angry little Jamaican man with his young son. Called bc my toilet isn't working properly. Came down to charge me $150 just to tell me wat I already told him. Then told me he had another job so he just came to look at this one. I paid him just to leave my house. Would never recommend these people."

Full service pump and well service. We service all makes and models well pumps, tanks, pool pumps, sprinkler pumps, water softners, any well equipment. 24 hour service. Call for free estimates over the phone. All major credit cards accepted.

"When I called, they answered right away and when I explained the problem, I was told that they would be at my house between 12 - 1 pm. They were at the house before 12:30, and fixed the problem right away (the water tank bladder had broken). Now we have a bigger perfectly working tank - and our water pressure is better than it's ever been (I have a feeling the bladder had damage to it when we moved in, because the pressure was never good). The only problem is that when the phone was answered, I heard a voice say it was an Angie's list customer. However, we didn't get the 5% discount. Although, I did not print out the coupon and forgot to tell my husband about it. Either way, their service was prompt and well done. Thank you!"

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
