"This company is good about making service calls in a timely manner. However, I was very disappointed in the work. I believe they mis-diagnosed the problem with my refrigerator by not taking the proper time and thoroughness required to make an accurate diagnosis. So, I was charged $95 for the service call and $330 for the repair that did not fix the problem. I called them out again and they did waive the service charge since it was within 30 days. This time they diagnosed a different problem quoting me $960 to fix it. So, basically, I am out $430 for a fridge that still has a broken ice maker. No way am I going to pay another $960. Ridiculous."

Advanced Plumbing Systems was started in June of 2015 by Ricky and Kristin Hinson. Although we are a new company, I have been a Journeyman Plumber serving the Franklin County and surrounding areas for over 15 years. I have worked for a few and select reputable contractors in the area. After years of working for others, it was time to better serve the area personally.

"Excellent!! Eric and fellow coworker did a great job. I will use Advanced Plumbing from here in out and highly recommend them to all my friends. Thank you so much!"

Owner operated since 2015 serving all of your Plumbing and Electrical needs. New construction, repair and installation. No job is too small or too big. Great customer service and competitive pricing.

"LCS Plumbing & Electrical LLC installed new waterlines, tub and fixtures in my bathroom during our recent remodel, they also cleaned our water heater and installed new elements. Their response time and workmanship were excellent! I'm like most people, I hate calling repair services, because you always seem to get someone that wants to run through the job and over charge, but not LCS! I definitely recommend them for any plumbing or electrical needs."

Water Softeners questions, answered by experts

Choosing involves understanding water hardness levels, household size, desired features, and consulting professionals experienced in suitable system types.

Drinking hard water is not known to have any negative health impacts. Using hard water can lead to dry skin and hair, and the minerals in hard water can build up in pipes, faucets, and appliances. Hard water is more of a threat to your plumbing than it is to your health.

The main difference between water softeners and water filters is that softeners remove hard minerals from the water, while filters have more of a blanket effect, removing all contaminants above a certain size. Filters are also much less expensive to install and protect against bacteria and other impurities. Depending on your water supply, you may need both.

No, a water descaler won't descale pipes. The charged water running through the pipes may very slowly dissolve mineral deposits and hold them inside the water, but it's a very gradual process. If your pipes do need descaling, it's much better to get a local plumber to descale your pipes.

A tankless water heater should be at least 10 feet away from a water softener, although the pros you hire for water softener installation can help you determine the correct distance. These two units need to have some distance between them to prevent hot water from the tankless water heater from flowing backward into the water softener when it runs a regeneration cycle.
