"Long Holiday Weekend and my hot water heater quit. We had just moved in too. That should have been caught in inspection. Oh well. By chance we had HVAC repair scheduled and they offered to look at the water heater, but My Guy already squeezed us into his schedule. I'm so glad he did. His price came in lower than the HVAC service person's quote. My Guy provided options for repair vs replacement. Knowledge is power, and I feel we were given all the information up front. We opted to replace. He showed us how to operate the water heater and told us the schedule for maintenance to get the longest use of our new water heater. I highly recommend My Guy. We'll have him back again when we replace the sink and dishwasher."

"

My son-in-law installed a new faucet I had purchased a couple years ago, but never installed.  He did a great job but when he turned it on the water just trickled out.  He was unable to determine the problem so I called Noble Plumbing.  I found his listing on Angie's List.

He was able to find that the hose running through the faucet was plugged with something, clear it, and put it back together.  It works great now.  He even found a leaking supply line and replaced it.

I asked him if he had time for another small job, fixing the loose faucet on my jetted tub.  The only access was through an access under my sink.  It was a very tight squeeze and around plumbing lines, but he was able to get it tightened and working fine.

He is great to work with and very professional at his job.  He did great work.

"The first technician believed what we thought, that our old hot water heater was leaking. He did a very professional job and quickly replaced it. Sadly, that wasn't it. And the 2nd techincian had some ideas of cause of leak, but it's been over one week and I've not gotten any quote of ideas to fix. The first technician did such a nice job he helped out weigh the cost and 2nd guy's lack of follow through."

"The tech showed up as promised and had provided me with a notification that he was on his way. He spent considerable time trying to locate the problem with the water pipes. Ultimately he determined that there wasn't a significant problem, but did recommend a permanent solution to the issue. He provided me with an estimate to take care of the pipe issue and additional estimates for two other projects that need to be done in the house. I was very happy with the entire process."

"From start to finish Plumbline Pro is amazing. He walked me through all the parts needed. But never felt once I was being upsold or lied to. He's right to the point no nonsense. I hope I don't ever need to call him but I know that he is reliable and will be there if I need help at any time."

Water Softeners FAQs, answered by experts

No, hard water isn’t dangerous. The added calcium in hard water can contribute to good bone health. However, it can also cause dry skin and hair. If you have dry skin or hair, consider using a water-softening system to help minimize the minerals in your water. Plus, these systems can also add some sodium to your diet. 

Softener systems extend appliance life spans, improve skin and hair health, and reduce pipe buildup by removing minerals like calcium and magnesium.

A water softener is a worthwhile investment if you live in an area with hard water. While hard water is safe to drink, it contains minerals like calcium and magnesium that can cause significant problems over time. These minerals build up inside pipes, reducing water flow and eventually corroding the plumbing system, which can lead to leaks and a shortened lifespan. Hard water also damages fixtures and appliances, potentially resulting in costly repairs. Additionally, it makes soaps and detergents less effective, meaning you'll use more product to get things clean. By installing a water softener, you can prevent these issues. The initial investment is often recouped through long-term savings, including lower energy bills, reduced appliance and plumbing maintenance, and spending less on soap and cleaning supplies. Other benefits include cleaner linens, dishes, and clothing, as well as softer water that is gentler on your skin and hair. In some areas, a water softener can also increase your home's value, making it a valuable long-term investment.

You can install a water softener system by turning off the water supply, draining the water, and then connecting your device to the waterline. Next, you’ll fill your tank with the recommended amount of salt or brine (whichever your unit calls for; be sure to read the instructions). Turn the water supply on and check for leaks. You can opt to let your water run for a few minutes, then test it using strips. 

The process of inspecting your water softener system is similar.

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.
