"Perfect! Doug is an expert Plumber that knows private water system. He removed the old equipment and installed the new. Everything is still working great. The work was done almost 13 years ago. We used all Top of the line Gould Equipment. I probably should call Doug to replace it again because breakdowns with the water system can leave you stranded."
Do you know if your sump is still working? We also have sump pumps avialable to protect you from power outages. That’s right no power no problem forget about the “battery back up” sump pumps if you have municipal water supply this is the way to go call today for details !

"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."

"Darren, the Salesman, was extremely knowledgeable and helpful. Very low pressure sale tactics, but laid out all of the options for you. The crew came and finished installing a new heat pump and heat exchanger in a half day and then another individual returned the next day to install a new water heater. Great communication and attention to detail every step of the way! Would highly recommend!"

"I met Jeff at my daughter's house to have several things done: replace her ultraviolet bulb, replace her water filter, hook up her water softener (she had recently purchased her home), and her washer needed the P trap put in which she had purchased. Jeff did all those things and checked her well system (the tank needed air). I was so pleased with Jeff's work and so glad there is an Angie's list! I had an appointment with a water treatment co. to change my ultraviolet light and cancelled it. Jeff came and changed the bulb, checked out my water softener, and put air in the water tank (which was not done ever by the repair guy from the water treatment co. I've used for years). Jeff listed things that would need to be replaced on the well gauge and switch and softener down the road. My husband appreciates the pressure in the shower! Excellent work. Considering the water conditioning guys charge $196 for only changing the bulb, we will definitely use Jeff's American Clean Water each year."

Water Heaters questions, answered by experts

We recommend you turn off the unit, the power, and the water supply as soon as you notice a leak. Your water heater tank should have a dedicated shut-off valve located on the cold inlet pipes. If the valve is broken or inoperable, use the shut-off valve to your home's main water supply to stop the flow to the entire house.

Avoid touching valves or pipes directly without confirming if they are hot. Wear gloves and other safety gear to keep from coming into contact with hot levers or components when turning off your leaking water heater.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.

Basements, specifically those without any air conditioning, are the best location for a hybrid water heater. These rooms are less likely to experience extreme temperature fluctuations, which can affect your hybrid water heater’s efficiency and performance. Basements often have more than enough space for their tanks and proper air circulation. Hybrid water heaters can also be a bit noisy, but putting them in your basement will keep the noise away from your main living areas.

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.

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.
