"SwiftPro was excellent. When our hot water heater went out (at nearly 20 years old, we were neither upset nor surprised!) we reached out to a few places but SwiftPro was the most responsive and had the price was fair. Zabi, the service technician was fantastic. I can’t say enough good things about him. He was prompt, provided excellent communication, took meticulous care with the work and work space, and was just a great person to talk to. The install went great and there was no aggressive sales tactics or upselling. Just a genuine cut and dry hot water heater removal and install experience. I highly recommend SwiftPro. Thanks Zabi!"

"RightNow Plumbing reliably provides competent, scrupulous, trustworthy service. Recently I engaged Andy to service our well-water acid neutralizer tank, because I questioned the reliability of service by another company 13 months earlier. Andy tested our water and found that its pH value was 6.97, which was consistent with previous readings over the past six months when he did other work for us. Because our well-water pH is essentially neutral, Andy explained the acid neutralizer tank is not necessary. He offered two options: 1) remove the tank (thus leaving us with only the water softener tank) or 2) empty it, which option I selected. He also reduced the cost of the service call. Andy’s approach starkly contrasts with the other company that for years took advantage of an unsuspecting customer by charging almost $300 to “service” the tank and unnecessarily adding expensive calcite. For competent, scrupulous, trustworthy service, call RightNow Plumbing. Posted May 14, 2025"

"Jamie our plumber arrived right on time & very efficiently performed three jobs for us. These included replacing a kitchen disposal, installing a vanity water faucet, flushing the water heater. He patiently explained each task and stayed until all were completed. We were so pleased we've entered into a service contract with Beacon Home Services."

"The company technicians, Steven, James and Zack were very professional and competent. They did excellent job in both removing the old unit and installing the new one. In addition to this job, we have used Appleton Campbell for several projects over the past couple of years, to include, installing a back up propane generator, installing replacement electrical lighting, and replacing a hot water heater. The company and their personal, to include both field and office individuals, were very competent and courteous. We highly recommend this company to other individuals."

"This company went above and beyond working to get us water without digging a new well as other companies suggested. I will hire for any and all plumbing I may have in the future because I know they will do the job right and not walk away until completed."

"They were very prompt and courteous. They were very efficient and had our water heater and water pressure values replaced with less than hour of work. Best of all , the cost was 60% less than the amount the large A/c and Plumbing company was going to charge us."

Water Softeners FAQs, answered by experts

Generally, it is safe to bathe in yellow water, as the color is often caused by iron, tannins, or rust, which won't harm your skin. Soap will still clean you effectively, though the water might leave stains. However, if the water has an unusual smell or you suspect contamination, avoid bathing and contact a plumber for an inspection. A professional can also help if you find bathing in yellow water problematic and want to determine how to get your water clear again.

Because it’s been through the water cycle, evaporating and becoming slightly acidic thanks to dissolved carbon dioxide in the atmosphere, rainwater tends to be naturally soft compared to groundwater, which has just been in contact with limestone. However, the natural hardness level of water always depends on where you are and other factors.

Some shower water softeners are effective, but this isn’t always the case. Most shower filters only filter out chlorine, not hard minerals like calcium. Other shower filters can't handle the demand in homes with very hard water. It's also important to change the filters on your shower filters. Failure to regularly swap out old filters will make the filter ineffective over time. 

While it depends on how complicated the unit and installation is, it takes two to four hours to install a water softener unit, on average. It might take longer if pipes need to be replaced. You should make sure the installation area is clear of any objects that might get in the way before you begin.

Hard water isn’t necessarily bad for you. In some ways, it’s good for you. If you’re deficient in magnesium or calcium, hard water can give you a mineral boost that you wouldn’t get with soft water. However, this is where the benefits of hard water pretty much stop. Hard water can cause many minor inconveniences and lead to costly, premature replacements of your water-using appliances.
