"We needed all the pipes replaced in our house. We also switched to a tankless water heater. Dustin came to give us an estimate and advise when they could start the project. We had gotten a couple of estimates but something just felt different with them. We liked that we received an email with who would be coming to give us an estimate as well as a picture of the technician we should expect. It was so refreshing working with this company it reminded me of company's 50 years ago with values and a caring staff. Dustin, Mike and Anatoily had what I will refer to as the three P's. They were professional, punctual and personable. They laid drop cloths and cleaned up everyday after themselves. They even finished the job a day early than projected as we were scheduled to go out of town for five days. I would highly recommend Honest Sewer & Drain. By the other positive reviews you guys are doing a fantastic job. Keep up the good work and it was a real pleasure doing business with you."

"Nathan was sent to help my 80-year-old mother replace the angle stops under her kitchen sink. She called me afterwards and explained that she really liked Nathan. He was polite and did a nice, clean job. Remaining tidy during a house project was important to her. The only miss was that he forgot to turn the hot water angle stop back on."

"This company was very professional. Once they arrived the installation went very smoothly. We were very pleased with the result. We love the system that Don recommended. It did not disappoint. This company was available and truly helpful with any questions we had about our new system. The maintenance service they provide is on time and very efficient. One thing that was a standout for me was I did not know they had even been on my property. I have had other companies not clean up after themselves which was not the case with 2 plumbs up. I highly recommend this company."

"Called via phone, asked for an estimate and was quoted a great price. I called another company prior to calling 5 Star Plumbing and another company wanted to charge me 4 times the amount. Peter arrived early, installed the part, and tested the water heater. Provided excellent work and customer service. Highly recommend and would use his services again. Peter also came out within 10-15 minutes after speaking to him since we're located nearby. Thanks!"

Water Softeners questions, answered by experts

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.

You can decide whether you need a water softener or water filter based on how your bathing or laundry experience is. If you notice issues like limescale buildup, dry skin, or stains on dishes—all telltale signs of hard water—you'd likely benefit from a water softener. However, if your main concern is over chemicals or bacteria in your tap water filter, and not just comfort, a filter is a better option.

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.

Yes, you can have both a water softener and a water filter. In fact, some manufacturers sell dual water softening and filtration systems that treat hard water and provide clean drinking water. If you’re unsure about what you need or want to discuss your options, reach out to a local water softener installation company.

Yes. To get soft water, you can install a water softening system, which will replace the calcium and magnesium ions in the water with sodium or potassium ions. Water softeners cost anywhere from $200 to $6,000, depending on the size and complexity of the system. You can either install a water softener for the whole house or just at your shower heads. If you’re sensitive to sodium or potassium, you can install a salt-free water conditioner.
